abstract = {This study empirically examines the determinants of heterogeneous firm-level cooperative R&D commercialization strategies. While the volume of interfirm collaboration has increased dramatically in recent decades, the determinants of firm-level choices among alternate modes of such cooperative activity remain relatively understudied. We develop a conceptual model of factors determining collaborative mode choice at the organizational portfolio level. These factors include the firm-level appropriation environment, in which deal-level choices have portfolio-level spillover implications, as well as governance capabilities developed by the firm over time. Using a random sample of innovating biotechnology start-ups, we assemble a firm-year panel dataset that aggregates transaction-level collaboration data to the firm-year level, allowing us to characterize firms' portfolios of collaborative deals. We find broad empirical support for our model, suggesting that a firm's appropriation environment and governance capabilities strongly influence portfolio-level collaboration mode choices. In addition, we explore the implications of governance capability development, finding that experience with particular modes, as well as deviations from existing capabilities, impact firm valuation.},

thicket_stance_extract={A firm’s patent portfolio can enable the firm to mitigate appropriation concerns that arise across multiple deals. This occurs when patents are not specific to an individual deal, but rather apply across multiple technology commercializa- tion projects. Such an intellectual property port- folio can thus act as a ‘patent thicket’ (Shapiro, 2000), making it more difficult for collaborative partners to expropriate the innovating firm’s tech- nology.11 The degree of protection afforded by such a portfolio will, of course, necessarily be dependent on the degree to which patents are rel- evant across multiple commercialization projects.},

abstract={Internet business method patents have been roundly criticized by most observers as being singularly inferior to most other patents. Many have even argued that business methods should not be patentable subject matter. As a result, Congress and the Patent and Trademark Office (“PTO”) singled them out for special treatment. All of these criticisms were, however, voiced without empirical support. We gathered data on most Internet business method patents issued through the end of 1999 and compared them with a large contemporaneous data set of patents in general. We also compared them with patents in fourteen individual technology areas within the general patent data set. Our comparison focused on several metrics that we believe serve as good proxies for patent quality and value. We found that Internet business method patents appear to have been no worse than the average patent, and possibly even better than most. They also appear to have been no worse, and possibly even better, than patents in most individual technology areas. These findings lead us to question the conventional wisdom that Internet business method patents were uniquely deficient. We briefly explore some possible explanations for the chasm between the accepted view and what we believe to have been the reality, including the possibility that negative opinions about these patents may have been the result of an information cascade. More importantly, we believe that efforts to single out these patents for special treatment not only lacked sound justification in the particular case but also reveal more fundamental problems associated with ex ante definitions to carve out any particular technology area for different treatment.},

abstract = {It is commonly asserted that innovation markets suffer from excessive intellectual property protections, which in turn stifle output. But empirical inquiries can neither confirm nor deny this assertion. Under the agnostic assumption that we cannot assess directly whether intellectual property coverage is excessive, an alternative query is proposed: can the market assess if any "propertization outcome" is excessive and then undertake actions to correct it? This process-based approach takes the view that innovator populations make rent-seeking investments that continuously select among innovation regimes that trade off securing innovation gains (which tends to demand more property) against reducing transaction costs and associated innovation losses (which tends to demand less). If we can identify the conditions under which privately interested investments in lobbying, enforcement, and transactional arrangements are likely to yield socially interested propertization outcomes, then the underlying datum at issue—whether there is "too much" intellectual property—can be determined indirectly at some reasonable degree of approximation. This approach identifies a "property trap" effect where, under high coordination costs, the regime selection mechanism is prone to fail: litigation risk and associated transaction cost burdens drive innovators to overconsume state-provided property rights. Conversely, under low coordination costs, the regime selection mechanism is prone to succeed: adversely affected entities that rely substantially on outside sources for innovation inputs have incentives to undertake actions that weaken property-rights coverage, including constrained enforcement, forming cooperative arrangements, or even forfeiting intellectual property to the public domain. Counterintuitively, these relationships imply that large firms that rely substantially on outside sources for innovation inputs tend to have the strongest incentives and capacities to take actions that correct overpropertization outcomes. Preliminary evidence is drawn from the semiconductor, financial services, and information technology industries.},

abstract={This article compares the relationship between patent quality and patent value in discrete and cumulative innovation. Using factor analysis and a set of various commonly used patent quality indicators including claims, citations and family size, we build a quality factor jointly driving all indicators for 9255 patents. We then test the significance of this quality factor for predicting patent renewal after 4, 8 and 12 years in an ordered logistic regression. Whereas we establish a robust and significant link between patent quality and value in samples of discrete and complex technology patents, there is no significant link for patents that are essential to technological standards. Consistently, neither the quality factor nor any single indicator allows predicting litigation on an essential patent. We conclude that while there is a robust link between patent quality and value in discrete innovation, this link is much weaker in cumulative innovation. Nevertheless, this affects only narrow, yet highly relevant, technological fields. There is no evidence that cumulativeness affects the relationship between quality and value in whole technological classes classified as “complex” by the literature.},

Building upon theoretical propositions drawn from Dequiedt and Versaevel (2007) and a database of 64.619 declarations of essential patents to major international Standard Developing Organizations (SDO), we investigate how patent pools influence the number of patents on a standard over time. While the high number of patents in ICT technologies is increasingly recognized as hampering the implementation of standards, this is the first thorough empirical analysis of the driving factors of this patent inflation. We control for a wide array of factors relating to standardization and the technological field to isolate the incremental effect of patent pools. We find that patent pools increase the number of essential patents especially through patent races in view of patent pool creation.

abstract={The emergent field of nanotechnology (NT) is currently very active worldwide with respect to intellectual property rights (IPR), especially patents, with both developed and developing countries joining in the nano-patents race. With the emergence of any new technology, nanotechnology creates opportunities as well as challenges in adapting the patent regime to its particular context. There is some consensus that patenting NT innovations poses more porblems than other technologies, owing to their multi-disciplinary character, cross-sectoral applications, broad claims as well as difficulties in fulfilling the patentability criteria of novelty, non-obviousness and industrial application. This is aggravated by a lack of standardized terminology which impedes easy identification of nano-patents and also the fact that patent offices may not be well-equipped to handle nanotechnology. These problems are likely to be compounded for developing and least developed countries, which irrespective of their state of technological advancement, and capacity of the domestic regime, are obliged to confed IPR in the new technology. This paper seeks to examine the challenges which patenting of NT entails for the patent regimes of nations and how these could be addressed. it relies on a study of the patent regimes and case laws of other countries, namely, the United States to draw lessons for India. The low volume of NT patent applications and grants at the Indian Patent office and lack of Indian case laws on teh subject make the discussion anticipatory and suggestive in nature. The paper finally arrives at certain recommendations, to help reconcile the need to incentivize innovation in the new technology, with the imperative of ensuring that the public interest is served and access to the patented knowledge is not hindered.},

It indicates that vigorous oligopolistic competition, particularly in high-tech industries, forces firms to keep innovating in order to survive. This leads them to internalize innovative activities rather than leaving them to independent inventors, and turns invention into an assembly-line process. The bulk of private R&D spending is shown to come from a tiny number of very large firms. Yet the revolutionary breakthroughs continue to come predominantly from small entrepreneurial enterprises, with large industry providing streams of incremental improvements that also add up to major contributions. Moreover, these firms voluntarily disseminate much of their innovative technology widely and rapidly, both as a major revenue source and in exchange for complementary technological property of other firms, including direct competitors. This helps to internalize the externalities of innovation and speeds elimination of obsolete technology. Some policy implications for industrialized and developing countries are also discussed.},

abstract={During the past decade, a swarm of patent applications pertaining to nanotechnology has been arriving at all the major patent offices of the world, including the US Patent and Trademark office (USPTO). As companies develop products and processes and begin to seek commercial applications for their inventions, securing valid and defensible patent protection will be vital to their long-term survival. In the decades to come, with nanotechnology further maturing and the promised breakthroughs accruing, patents will generate licensing revenue, provide leverage in deals and mergers, and reduce the likelihood of infringement. Because development of nanotech-related products is extremely research intensive, without the market exclusivity offered by a US patent, development of these products and their commercial viability in the marketplace will be significantly hampered. In this paper, effects of 'nanopatent gold rush' that is underway by 'patent prospectors' as start-ups are highlighted whereby corporations compete to lock up broad patents in these critical early days. In fact, the entire US patent system is under greater scrutiny and strain, with the USPTO continuing to struggle with evaluating nanotech-related patent applications.

abstract={There is enormous excitement and expectation regarding nanotechnology's potential impact. However, securing valid and defensible patent protection will be critical here. Although early forecasts for nanotechnology commercialization are encouraging, there are bottlenecks as well. One of the major hurdles is an emerging thicket of patent claims, resulting primarily from patent proliferation, but also because of issuance of surprisingly broad patents by the U.S. Patent and Trademark Office (PTO). Adding to this confusion is the fact taht the U.S. National Nanotechnology Initiative's widely-cited definition of nanotechnology is inaccurate and irrelevant. This has also resulted in the PTO's flawed nanotechnology patent classification system. All of this is creating a chaotic, tangled patent landscape in vairous sectors of nanotechnology (e.g., nanoelectronics and nanomedicine) in which competing players are unsure as to the validity and enforceability of numerous issued patents. If this trend continues, it could stifle competition, limit access to some inventions and simply grind commercialization efforts to a halt. Therefore, reforms are urgently needed at the PTO to address problems ranging from poor patent quality and questionable examiniation practices to iinadequate search capabilities, rising attrition, poor employee morale, and a skyrocketing patent application backlog. Only a robust patent system will stimulate the development of commercially viable nanotechnology products.},

In addition, there are several thousand additional patent applications typically in the process of review.' 4 As a result of these extant and forthcoming patents, it is virtually impossible for a firm to know, ex ante, whether a given microprocessor innovation will infringe a patent held by another firm.

But when technologies are complex, this property right is defective: ownership of a product’s technology is shared, not exclusive. In that case I show that if patent standards are low, firms build “thickets” of patents, especially incumbent firms in mature industries. When they assert these patents, innovators are forced to share rents under cross-licenses, making R&D incentives sub-optimal. On the other hand, when lead time advantages are significant and patent standards are high, firms pursue strategies of “mutual non-aggression.” Then R&D incentives are stronger, even optimal.},

abstract = {One of the most revolutionary legal changes in the past generation has been the "propertization" of intellectual property (IP). The duration and scope of rights expand without limit, and courts and companies treat IP as absolute property, bereft of any restraints. But astonishingly, scholars have not yet recognized that propertization also can lead to the narrowing of IP. In contrast to much of the literature, which criticizes the propertization of IP, this Article takes it as a given. For the transformation is irreversible, sinking its tentacles further into public and corporate consciousness (as well as the IP laws) with each passing day and precluding the likelihood that IP will return to the prepropertization era. This Article therefore ventures onto a new path, one that follows property into unexpected briar patches of limits. The secret here is that property is not as absolute as it is often claimed to be. After surveying fifty doctrines in property law, Professor Carrier synthesizes limits based on development, necessity, and equity. He then utilizes these limits to construct a new paradigm for IP. The paradigm facilitates the reorganization of defenses that courts currently recognize as well as a more robust set of defenses, which include (1) a new tripartite fair use doctrine in copyright law, (2) a new defense for public health emergencies and a recovered experimental use defense and reverse doctrine of equivalents in patent law, (3) a development-based limit to trademark dilution, and (4) a functional use defense for the right of publicity. By adopting the paradigm of property, IP has reopened the door to limits. Rediscovering these limits offers significant promise for the future of innovation and democracy.},

The model is calibrated to aggregate data of the US economy. Under parameter values that match key features of the US economy and show equilibrium R&D underinvestment, I find that optimizing the profit-sharing rule of blocking patents would lead to a significant increase in R&D, consumption and welfare.

Thepaper then assesses the current level of patent protection, exploiting estimates of the private and social returns to R&D taken from the empirical literature and other available sources. Although more research is needed for a more precise assessment, the evidence available suggests that patents do not overcompensate innovators.},

The proliferation and fragmentation of intellectual property rights creates a 'patent thicket' that is often viewed as an obstacle to innovation. Two main problems may emerge. First, a proliferation of patents held by different owners increases transaction costs and might even prevent manufacturers from obtaining the right to develop the new products, creating the tragedy of the anticommons (Heller and Eisenberg, 1998). Second, with complementary patents there may be a problem of Cournot complements (Shapiro, 2001) that increases the deadweight loss to profit ratio. },

A proprietary platform has a single provider that solely controls its technology (for example, Federal Express, Apple Macintosh, or Google). With a shared platform such as Visa, DVD, or Linux, multiple firms collaborate in developing the platform's technology and then compete in offering users different but compatible versions of the platform.

In this paper I study the previously neglected dynamic trade-off between litigating and cross-licensing that firms face to protect their intellectual property. I present a model of bargaining with learning in which firms’ decisions to litigate or crosslicense depend on their investments in technology specific assets. In particular the model predicts that where firms’ sunk costs are higher, their incentive to litigate and delay a cross-license agreement is lower. In addition, the bargaining game shows how firms with intermediate values of asset specificity tend to engage in inefficient "persuasive litigation". Using a novel dataset on the US semiconductor industry I obtain empirical results consistent with those suggested by the model. Combining model intuition with some empirical figures, I evaluate possible effects of the currently debated patent litigation reform.},

journal={Economia e Politica Industriale},

publisher={FrancoAngeli Editore},
abstract={Inventors and users of technology often enter into cooperative agreements for sharing their intellectual property in order to implement a standard or to avoid costly litigation. Over the past two decades, U.S. antitrust authorities have viewed pooling arrangements that integrate complementary, valid and essential patents as having procompetitive benefits in reducing prices, transactions costs, and the incidence of legal suits. Since patent pools are cooperative agreements, they also have the potential of suppressing competition if, for example, they harbor weak or invalid patents, dampen incentives to conduct research on innovations that compete with the pooled patents, foreclose competition from downstream product or upstream input markets, or raise prices on goods that compete with the pooled patents. In synthesizing the ideas advanced in the economic literature, this paper explores whether these antitrust concerns apply to pools with complementary patents and, if they do, the implications for competition policy to constrain them. Special attention is given to the application of the U.S. Department of Justice-Federal Trade Commission Guidelines for the Licensing of Intellectual Property (1995) and its companion Antitrust Enforcement and Intellectual Property Rights: Promoting Innovation and Competition (2007) to recent patent pool cases.},

Recognizing that intellectual property rights and competition law can interact in many different ways, the presentation focuses on several key issues. The economic literature on the interaction between competition law and intellectual property rights shows that these regulatory systems are consistent in terms of basic principles. Significant tensions exist, however, and it is difficult to balance IPR and competition law in practice. The significant differences in approach between the United States and the European Union simply reflect the underlying reality that efforts to achieve a sensible balance do not result in policy harmonization.},

Preemptive patenting has traditionally been practiced by the private sector as a competitive strategy, being driven by economic considerations. Recently, academics and patients/consumers have instituted preemptive patenting strategies as a way of ensuring access to genomic sequences for, respectively, research study purposes and life-enhancing access to diagnostic gene testing. To reduce this non-economic motivation for preemptive patenting by these nontraditional competitors, it is recommended that the biotechnology industry initiate a strategy of its own which will: (1) relax firm patent enforcement of genomic sequences that are essential for academic researchers to use in their studies; and (2) provide for a ‘means-test’ approach that incorporates a ‘staggered’ fee-schedule for academic researchers to charge their subjects, i.e. patients, for gene tests and diagnostic results.},

Congress has set the legislation aside for the time being, but will likely revisit the issue again shortly. The biotechnology industry, one of the fastest growing sectors in the United States economy, strongly opposes many of the proposed reforms. This paper considers the Congressional testimonies of the Biotechnology Industry Organization (“BIO”) and other representatives of biotechnology’s interests, and finds that the industry’s adamant opposition to many of the proposals is driven largely by a belief that biotechnology patents function primarily as tools for securing investment funding, and the fear that investment in biotechnology will be adversely impacted if investors perceive that patent reform has weakened the rights of patent owners and inventors. The paper also considers how the biotechnology sector might be impacted if the proposed reforms are enacted into law, and describes some recent biotechnology cases wherein the outcome might have been different if the reforms had already been in place.},

Human gene patent litigation invariably has involved an alleged infringer engaged in substantial commercial activities focused specifically on the single gene that is the subject of the asserted patent, the antithesis of a patent thicket scenario (14). Some have speculated that DNA microarray technology is particularly at risk of becoming entangled in a thicket (6). However, I found no instance in which a human gene patent was asserted against the manufacturer or user of microarray technology, although microarray companies have experienced substantial patent litigation involving nongene patents since the mid-1990s.},

abstract={The pharmaceutical and biotechnology industries have long relied on pat- enting as the primary means of allocating ownership and control over new discoveries. Yet, patent protection is a double-edged sword that has major implications for the future of innovation in biomedical science in the United States. Excessive “upstream” patenting of genes and molecular targets could hinder further research by creating a need for expensive and inefficient cross-licensing. However, limiting such basic science patenting could allow pri- vate entities to use the results of years of costly publicly funded research to produce and market lucrative products without compensating university- or public sector–based innovators. Academic and other nonprofit research cen- ters would, therefore, be deprived of revenue for pursuing novel therapeu- tics or other seminal research work that may not be patentable. Recent court cases illustrate the inherent conflicts in allocating ownership and control of basic biomedical discoveries. Several options exist to avoid the complex prob- lems of overlapping basic science patents while still rewarding pivotal discoveries and encouraging further innovation. These include establishing ba- sic science patent pools and mandating arbitration arrangements that would assign credit and royalties for biotechnology innovations that depend on prior research that was performed, financed, or both in the public sector.},

abstract = {Commentators have poured forth a loud and sustained outcry over the past few years that sees property rule treatment of intellectual property (IP) as a cause of excessive transaction costs, thickets, anticommons, hold-ups, hold-outs, and trolls, which unduly tax and retard innovation, competition, and economic growth. The popular response has been to seek a legislative shift towards some limited use of weaker, liability rule treatment, usually portrayed as “just enough” to facilitate transactions in those special cases where the bargaining problems are at their worst and where escape hatches are most needed. This essay is designed to make two contributions. First, it shows how a set of changes in case law over just the past few years have hugely re-shaped the patent system from having several major, and helpful, liability-rule pressure-release valves, into a system that is fast becoming almost devoid of significant property rule characteristics, at least for those small entities that would most need property rule protection. The essay then explores some harmful effects of this shift, focusing on the ways liability rule treatment can seriously impede the beneficial deal-making mechanisms that facilitate innovation and competition. The basic intuition behind this bad effect of liability rules is that they seriously frustrate the ability for a market-challenging patentee to attract and hold the constructive attention of a potential contracting party (especially one that is a larger more established party) while preserving the option to terminate the negotiations in favor of striking a deal with a different party. At the same time, liability rules can have an additional bad effect of helping existing competitors to coordinate with each other over ways to keep out new entrants. The essay is designed to contribute to the literature on IP in particular, as well as the broader literatures on property and coordination, by first showing how a seemingly disconnected set of changes to the legal rules impacting a particular legal regime like the patent system can have unintended and sweeping harmful consequences, and then by exploring why within the more middle range of the spectrum between the two poles of property rules and liability rules, a general shift towards the property side may be preferred by those seeking an increase in access and competition.},

This paper uses the example of the first patent pool in U.S. history, the Sewing Machine Combination (1856-1877) to perform the first empirical test of the effects of a patent pool on innovation. Contrary to theoretical predictions, the sewing machine pool appears to have discouraged patenting and innovation, in particular for the members of the pool.

We find that litigation risk is much higher for patents that are owned by individuals and firms with small patent portfolios. Patentees with a large portfolio of patents to trade, or other characteristics that facilitate “cooperative” resolution of disputes, are much less likely to prosecute infringement suits. However, postsuit outcomes do not depend on these characteristics. These findings show that small patentees are at a significant disadvantage in protecting their patent rights because their greater litigation risk is not offset by more rapid resolution of their suits. Our empirical estimates of the heterogeneity in litigation risk can help in developing private patent litigation insurance to mitigate the adverse affects of high enforcement costs.},

They are an attractive option for fragmented patent landscapes, where they are created in hopes of avoiding the high cost associated with acquiring numerous licensing agreements, avoid widespread patent disputes, and help create a standard, amongst other reasons. This issue is especially relevant to the emerging scientific field of nanotechnology, where there is widespread concern about the fragmentation of the intellectual property landscape. This paper aimed to develop a general list of criteria to aid in determining whether patent pools are a viable option for a market by examining relevant literature and conducting interviews; it was then applied to the dendritic nanotechnology’s drug delivery and pharmaceutical applications. The completed list had nine criteria and, when applied to the dendritic nanotechnology market, concludes that a patent pool will not be necessary for the continued advancement of this application. The primary reason is that a huge amount of patents are in control of one company alone, Dendritic Nanotechnologies, and seem to be the primary source for the most highly sought after dendritic patents.},

year={2006},
abstract={We study several interconnected problems that arise under the current U.S. patent system when a patent covers one component or feature of a complex product. This situation is common in the information technology sector of the economy. Our analysis applies to cases involving reasonable royalties, but not lost profits. First, we show using bargaining theory that the threat to obtain a permanent injunction greatly enhances the patent holder’s negotiating power, leading to royalty rates that exceed a natural benchmark range based on the value of the patented technology and the strength of the patent. Such royalty overcharges are especially great for weak patents covering a minor feature of a product with a sizeable price/cost margin, including products sold by firms that themselves have made substantial R&D investments. These royalty overcharges do not disappear even if the allegedly infringing firm is fully aware of the patent when it initially designs its product. However, the hold-up problems caused by the threat of injunctions are reduced if courts regularly grant stays to permanent injunctions to give defendants time to redesign their products to avoid infringement when this is possible. Second, we show how hold-up problems are magnified in the presence of royalty stacking, i.e., when multiple patents read on a single product. Third, using third-generation cellular telephones and Wi-Fi as leading examples, we illustrate that royalty stacking can become a very serious problem, especially in the standard-setting context where hundreds or even thousands of patents can read on a single product standard. Fourth, we discuss the use of “reasonable royalties” to award damages in patent infringement cases. We report empirical results regarding the measurement of “reasonable royalties” by the courts and identify various practical problems that tend to lead courts to over-estimate “reasonable royalties” in the presence of royalty stacking. Finally, we make suggestions for patent reform based on our theoretical and empirical findings.},

abstract={Universities and companies are rushing to the patent office in record numbers to patent nanotechnology inventions. This rush to the patent office is so signficant that many law firms have established nanotechnology practice groups and the U.S. Patent and Trademark Office has now created a new technology class designed to track nanotechnology products. Three big differences between the emerging science of nanotechnology and other inventions make the role of patents more significant in this arena than elsewhere. First, this is almost the first new field in a century in which the basic ideas are being patented at the outset. In many of the most important fields of invention over the past century - computer hardware, software, the Internet, even biotechnology- the basic building blocks of the field were either unpatented or teh patents were amde available to all users by government regulation. In others, patents were delayed by interferences for so long that the industry developed free from their influence. In nanotechnology, by contrast, companies and universities alike are patenting early and often. A second factor distinguishing nanotechnology is its unique cross-industry structure. Unlike other new industries, in which the patentees are largerly actual or at least potential participants in the market, a significant number of nanotechnology patentees will own rights not just in the industry in which they participate, but in other industries as well.This overlap may signficantly affect thier incentives to license the patents. Finally, a large number of the basic nanotechnology patents have been issued to universities, which have become far more active in patenting in the last twenty-five years. While universities have no direct incentive to restrict competition, their interests may or may not align with the optimal implementation of building-block nanotechnology inventions. The result is a nascent market in which a patent thicket is in theory a serious risk. Whether it will prove a problem in practice depends in large part on how efficient the licensing market turns out to be.},

Second, even if other firms agree to license their patents at a modest rate, a hold-out problem may result if a single firm then sets a high license fee for its technology Finally, the very process of arranging the needed licenses may prove to be time consuming.

This paper examines the reduction of software copyright protection in the Lotus v. Borland decision.

We find that the firms affected by the diminution of copyright protection disproportionately accelerated their patenting in subsequent years. But little evidence can be found for any harmful effects on firms' performance and incentive to innovate: in fact, the increased reliance on patents is correlated with growth in measures such as sales and R&D expenditures.},

As a consequence the patent system affects both the revenues and the cost of the innovator. We construct a model of sequential innovation in which an innovator uses n patented inputs in R&D to invent a new product. We ask three questions: (i) what is the net effect of patents on innovation as technologies become more complex (n increases)? (ii) are patent pools welfare enhancing? (iii) what is the optimal response of patent policy as technological complexity increases? We find that the answers to these questions depend on the degree of complementarity and substitutability between the inputs used in research.},

On the other hand, when the inputs are substitutes, the profitability of the innovation is increasing in technological complexity.

year={2011},
abstract={Many key industries (e.g., biomedical, pharmaceuticals, telecommunications, and information technologies) are characterized by cumulative innovations, where the introduction of a new product or service often requires many complementary technologies. When these technologies are protected by intellectual property rights owned by many firms, patent thickets exist, which researchers have argued may hinder the development of cumulative innovations. Specifically, patent thickets may lead to excessive royalty burdens for potential licensees, which is called ‘‘royalty stacking,’’ and if such costs are passed on to consumers, prices of products based on cumulative technologies will be driven up, dubbed as ‘‘double marginalization.’’ The literature, however, does not address these issues under different forms of licensing contracts. This article develops a game-theoretic model where a downstream firm seeks to license N patents that read on its product from upstream firms. It discusses a variety of licensing forms widely used in practice and attempts to discover whether royalty stacking and double marginalization occur under these forms of licenses. It also studies the impact of bargaining power between parties. It is found that when patent ownership becomes more fragmented, neither royalty stacking nor double marginalization occurs under profit-based royalty, fixed fee, and hybrid licenses. Such problems occur only under pure quantity-based or pure revenue-based royalty licenses when the downstream firm’s bargaining power is low. It is also shown that no matter how fragmented the ownership structure of patent is, hybrid licenses consisting of a fixed fee and a quantity- or revenue-based royalty rate lead to the same market outcomes as a fully integrated firm that owns all the patents and the downstream market. This article has interesting implications for both research and practice. First, the results show that even under the same patent ownership structure, different forms of licenses lead to quite different market outcomes. Therefore, it is suggested that firms and policy makers pay more attention to contractual forms of licenses when trying to minimize the negative impact of patent thickets. Second, the extant literature has largely assumed that quantity-based royalties are used, where double marginalization is the most severe. In practice, revenue-based royalties are most common, under which double marginalization is much milder. Third, the results show that patent pools can be most effective in mitigating royalty stacking and double marginalization when quantity-based or revenue-based royalties are the sole or primary payment form, especially when downstream firms have low bargaining power.},

abstract={Patents are effective tools for promoting innovation in the pharmaceutical sector. Originator companies should be able to recoup their R & D investments during the term of the basic patent / SPC on an active pharmaceutical substance. Generic competition should be available immediately after expiry of that term. The chances of market entry for generic medicines companies in all markets the day following expiry of the main basic patent in all European Union markets is, however, not possible or, at best, is extremely diffi cult. Due to a diminishing number of newly registered products and contracting product pipelines, originator companies may be tempted to unjustly prolong the patent monopoly of existing products. The result is known as the ‘ evergreening ’ of a basic patent with the help of follow-on patents to keep generic competitors off the market. These follow-on patents are often weak or trivial and, upon careful examination, it is clear that they should never have been granted. Patent quality is therefore of the utmost importance. The European patent system should only reward true inventions and should discourage patent applications for ordinary innovation. An important way of reducing the incidence of poor quality follow-on patents is to remedy certain structural defi ciencies and weaknesses in the current examination procedure. Priority must be given to ensuring that the European Patent Offi ce (EPO) has the resources it needs to continue to improve the quality of patent examiners, along with their training and remuneration, and to increase the number of more experienced senior examiners in order to give every patent application the deliberate, expert review it deserves. This would lead to a more stringent application of the patentability requirements and fewer trivial patents. Applicants should be more rigorously required to provide patent applications of the highest quality accompanied by all relevant information at the start of the examination process. Similarly, they should be under obligation to disclose all information known to them that is material to the patentability of their invention. Furthermore, better third-party participation would also help to avoid inappropriate follow-on patents from being granted. When such patents are granted, an immediate review should be possible to avoid the assertion of ultimately invalid patents to hinder generic competition. This would require an acceleration of the current opposition proceedings that today can take many years. The structure established under the European Patent Convention only provides for a common and single European patent application and granting system by the EPO. A European patent is not a unitary patent, but essentially a bundle of national patents. As a result, questions of patent infringement and validity are governed by various national laws and are handled by the national courts operating under different procedural rules. This purely national litigation system results in a complex arena of multiple patent litigation involving high costs, forum shopping and diverging, even contradictory, court decisions. The lack of a central judiciary composed of experienced patent judges is regarded as one of the major defects in the current patent system. An effective solution would be the creation of a central European patent court that would deal with questions of invalidity and infringement at a pan-European level. Until this has been achieved, specialised national patent courts should be created with technically skilled judges with powers to reach a decision within an acceptable timeframe. Furthermore, the standard for obtaining an interim injunction should be returned to its roots as an equitable remedy since injunctions today are often used simply as a litigious tactic. This change would require a litigant to establish the existence of irreparable harm that cannot be compensated by monetary damages before a court would take the far-reaching step of enjoining a product. Finally, measures should be taken to ensure that originator companies do not use other means to unjustly prolong their monopoly by, for example, introducing a system of patent linkage, obtaining improperly granted SPCs, deploying inaccurate marketing campaigns for promoting ‘ new ’ products with no substantial added therapeutic value as innovative products, etc.},

abstract={The patent system was initially designed to provide incentives to develop stand-alone innovations in fi?elds such as mechanics, chemicals or pharmaceuticals. Its application is therefore problematical in more recent ?elds such as biotechnology and ICT industries, where innovation patterns are different. A well-known problem concerns cumulative innovations. Patent law must then trade off the rights granted to upstream patent owners with the incentives to develop subsequent innovations (Scotchmer, 1991; Donoghue, Scotchmer and Thisse, 1998; Denicolò, 2000). Another issue concerns complementary innovations, which are the focus of the paper. When ?final products embody several complementary innovations, the scattering of patents between various owners jeopardizes the commercial exploitation of the products because of negotiation and royalty stacking issues (Merges & Nelson, 1990; Heller & Eisenberg, 1998; Shapiro, 2001). In biotechnology, this is the case of therapeutic proteins or genetic diagnostic tests that require the use of multiple patented gene fragments (Heller & Eisenberg, 1998). It is also very frequent in ICT industries such as electronics, computer hardware and software, where ?firms have to navigate "patent thickets" (Shapiro, 2001). Shapiro (2001) reports, for example, that in the semi-conductor industry ?rms receive ?thousands of patents each year and manufacturers can potentially infringe on hundreds of patents with a single product". The situation is similar in the U.S. software industry, where there are ?potentially dozens or hundreds of patents covering individual components of a product?(FTC, 2003). I study the problem of the production of complementary innovations in a model of dynamic R&D competition between two ?firms, and argue that in some cases complementary innovations should not be patentable as such, but bundled with other innovations prior to patenting. To do so I consider two complementary innovations and examine whether they should be patented separately or as a bundle. This approach echoes several papers on cumulative innovations where patentability requirements are de?ned as the need to develop two or more successive innovations before obtaining a patent (Scotchmer and Green, 1990; Hunt, 1995; O?Donoghue, Scotchmer and Thisse, 1998; Denicolò, 2000). As regards complementary innovations, the optimal patenting rule depends on a trade-off between the pro?fit loss due to scattered complementary patents, and the possible bene?fit of patent disclosure. The scattering of complementary patents between different owners creates a double marginalization issue. Since each patentee behaves as a monopolist, the Cournot (1838) theorem predicts that prices do not maximize the ?rms?pro?ts (Shapiro, 2001; Lerner & Tirole, 2005)1 . The requirement that complementary innovations be bundled prior to patenting can be a way to prevent this pro?t loss. However, small innovations are not disclosed when innovations have to be bundled prior to patenting (Scotchmer and Green, 1990). As a result, ?firms lose the possibility to quit the race after a ?first innovation has been patented, which leads to R&D cost duplications. I show that patent disclosure has a positive social effect, although it does not permit a fully effi cient coordination between ?firms. In this context, bundling innovations prior to patenting can be more effi cient if innovations can be devel- oped quickly. As I argue in the Conclusion, this condition is consistent with the legal de?nition of the "inventive step" patentability requirement. The paper is structured in six sections. First, the model is introduced in Section 2. Section 3 then considers the case in which innovations can be patented separately, while Section 4 focuses on the case in which they must be bundled prior to patenting. Section 5 compares the social outcomes of the two require- ments. Finally, Section 6 concludes and discusses the policy implications of the model.},

In 1996, to compound the rapid change of technology, the U.S. Supreme Court affirmed that business methods are also patentable. Hence in the current environment, scores of patents, assigned to many different parties, may cover a single electronic device or software—making it increasingly impossible to manufacture an electronic device without receiving a cease and desist letter or other notice from a patentee demanding a large royalty or threatening an injunction. Companies, particularly those in the high technology sector, have been asserting for some time now that they are under constant threat of lawsuits that threaten to shut them down. As a result, numerous radical changes to the U.S. Patent Act and patent practice before the U.S. Patent & Trademark Office have been proposed. Certain proposed changes, however, are meeting with resistance because of a reliance on long term patent protection and exclusivity of patent rights by different industries. Notwithstanding, certain foreign governments have already enacted provisions making it possible to obtain a compulsory patent license in the event that a patentee is not practicing his invention or is simply refusing to license the rights to his invention for a reasonable royalty fee.},

abstract={Nanotechnology is an emerging technology, and as an emerging technology, there are certain intellectual property issues surrounding the appropriate protection for nanotechnology. Broadly speaking, nanotechnology is the manufacture of structures and manipulation of matter within dimensions below 100 nanometers, where unique phenomena enable novel applications. At the nanoscale, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter.' Researchers and companies are attempting at applying these novel properties to a wide-range of applications and industries.' One important intellectual property issue in addressing nanotechnology is the patenting of innovative techniques and compositions of matter which are necessary for downstream innovation. The notion of a patent thicket is where an overlapping set of patent rights requires that those seeking to commercialize new technology obtain licenses from multiple patentees. If you get monopoly rights down at the bottom, "you may stifle competition that uses those patents later on and so the breadth and utilization of patent rights can be used not only to stifle competition, but also have adverse effects in the long run on innovation." The patent thicket problem in nanotechnology has been suggested by a recent report by LuxResearch (hereinafter "LuxReport"), indicating that many patents have been filed relating to nanomaterials with their claims overlapping.While many companies will want to use these nanomaterials, the LuxReport states these companies will be forced to license patents from many different sources. Potentially, there will be significant transactional costs for further nanotechnology developments due to these overlapping claims. Moreover, the quality of these nanotechnology patents has been repeatedly called into question," so the navigation of a patent thicket will have to be around these questionable patents. The legal principles in the written description requirement could clear some of this patent thicket by narrowing overlapping claims in nanotechnology during examination, litigation, and especially in postgrant procedures. This paper generally discusses 1) the background of the nanomaterials in the LuxReport and the patent thicket; 2) the legal principles within the written description requirement; 3) why the written description requirement should be used; 4) the application of the legal principles within the written description requirement to nanomaterials discussed in the LuxReport; and 5) proposals for the written description requirement for the USPTO, the Federal Circuit, and postgrant procedures.},

Although the Federal Circuit's approach may be justified by the fact-finding and policy application deficiencies of the trial courts and the Patent and Trademark Office (PTO), it has had a negative impact on innovation policy and has resulted in a patent system that is sorely in need of reform. This Article argues that because of the interdependence of the various institutions within the patent system, reform of the system must be both multi-institutional and closely attentive to the institutional competence of the system's actors. Although Congress should clearly bolster the PTO's fact-finding abilities, giving plenary responsibility over factual questions to the PTO would not be cost effective. Accordingly, Congress should endow the system with improved fact-finding expertise through the institution of specialized trial courts. As for actual policy formulation, each of the available institutional options--the legislature, the PTO, and the courts--has substantial associated liabilities. On balance, however, the Federal Circuit is probably best positioned to formulate patent policy, so long as the fact-finding expertise of inferior institutions is bolstered and additional appellate mechanisms are instituted. By paying attention to institutional design and revising our institutions accordingly, we can achieve the patent system we should have had all along.},

abstract={This paper examines the impact of the licensing policies of one or more upstream owners of essential intellectual property (IP hereafter) on the downstream firms that require access to that IP, as well as on consumers and social welfare. The paper considers a model in which there is product differentiation downstream. License fees and fixed entry costs determine the number of downstream competitors and thus variety. We first consider the case where there is a single upstream owner of essential IP. Increasing the number of licenses enhances product variety, which creates added value, but it also intensifies downstream competition, which dissipates profits. We derive conditions under which the upstream IP monopoly will then want to provide an excessive or insufficient number of licenses, relative to the number that maximizes consumer surplus or social welfare.When there are multiple owners of essential IP, royalty stacking can reduce the number of the downstream licensees, but also the downstream equilibrium prices the consumers face.The paper derives conditions determining whether this reduction in downstream price and variety is beneficial to consumers or society. Finally, the paper explores the impact of alternative licensing policies. With fixed license fees or royalties expressed as a percentage of the price, an upstream IP owner cannot control the intensity of downstream competition. In contrast, volumebased license fees (i.e., per-unit access fees), do permit an upstream owner to control downstream competition and to replicate the outcome of complete integration. The paper also shows that vertical integration can have little impact on downstream competition and licensing terms when IP owners charge fixed or volume-based access fees.},

abstract={Patents, patent litigation, and patent settlements increasingly influence competition. Settlements of patent disputes come in many forms,including licensing and cross-licensing agreements, patent pools, mergers, and joint ventures. While frequently procompetitive, such settlements can stifle competition and harm consumers. I propose a specific antitrust rule limiting such settlements: a settlement must leave consumers at least as well off as they would have been from ongoing patent litigation. After establishing that profitable settlements satisfying this constraint generally exist, I show how this antitrust rule can be used to evaluate three types of settlements: mergers, patent pools, and negotiated entry dates.},

abstract = {Abstract Production requiring licensing groups of complementary patents implements a coordination game among patent holders, who can price patents by choosing among combinations of fixed and royalty fees. Summed across patents, these fees become the total producer cost of the package of patents. Royalties, because they function as excise taxes, add to marginal costs, resulting in higher prices and reduced quantities of the downstream product and lower payoffs to the patent holders. Using fixed fees eliminates this inefficiency but yields a more complex coordination game in which there are multiple equilibria, which are very fragile in that small mistakes can lead the downstream firm to not license the technology, resulting in inefficient outcomes. We report on a laboratory market investigation of the efficiency effects of coordinated pricing of patents in a patent pool. We find that pool-like pricing agreements can yield fewer coordination failures in the pricing of complementary patents.},

abstract={The collective management of intellectual property rights is a term used to describe methods of managing large portfolios of intellectual property assets, including patents, copyrights, trademarks, know-how and data. Patent pools are one such mechanism. A “patent pool” is an agreement between two or more patent owners to license one or more of their patents to one another or to third parties.2 In its 2001 White Paper on Patent Pools, the USPTO said, “A patent pool allows interested parties to gather all the necessary tools to practice a certain technology in one place, e.g, ‘one-stop shopping,’ rather than obtaining licenses from each patent owner individually.”3 The following paper provides a summary of features of 35 patent pools organized or proposed from 1856 to the present. Each of the patent pools was organized in response to a particular set of policy objectives and circumstances. Their purposes were heterogeneous. Some were organized in order to promote the interests of monopolists or cartels. Others were organized to promote competition and benefit the users of patents. There are pools that manage the patents on standards for new information technologies, that enhance R&D for new biomedical or biotechnology agricultural products, or that seek to promote other objectives. Some pools are organized by patent owners, others by manufacturers, and yet others by non-profit institutions, including governments. There is no single reason for creating a patent pool and no single way to manage a patent pool.},

abstract={Nanotechnology's potential impact on worldwide industries has nations around the world investing billions of dollars for research in order to capture a part of the projected trillion dollar market for nanotechnology products in 2010. The current rush to patent nanotechnologies may lead to an overcrowded nanotechnology patent thicket that could deter critical innovation and continued product development in the United States. At this early stage of nanotechnology's life cycle, increasing numbers of broad and potentially overlapping patents are being issued--while few nonexclusive licenses are being offered. Furthermore, the lack of significant case law provides little guidance on proper nanotechnology patent scope and validity, while the decline of legal defenses such as experimental use leaves innovators exposed to potential infringement liability for even the most fundamental of scientific research studies. In this Comment, the author proposes that the U.S. government exercises the full extent of its rights under the twenty-five year old Bayh-Dole Act and develop the government license defense to create a limited patent compulsory licensing regime for the fruits of federally funded research. The author argues that recipients of the billions of dollars in federal nanotechnology research funds should provide broad, nonexclusive licenses to the privatized patent rights they obtain as a result of public funding. Ultimately, a well-formulated government license defense, which assesses the extent to which an "infringing" act against a federally funded patent falls along a spectrum of fair use, would provide a means for overcoming the innovation-impeding effects of absolute exclusion rights.},

Such an overlapping set of patent rights may have restrictive effects on further research and development of diagnostic tests, and the provision of clinical diagnostic services. Currently, two models that may facilitate access to and use of patented genetic inventions are attracting much debate in various national and international fora: patent pools and clearing houses. In this article, we explore the concept of clearing houses. Several types of clearing houses are identified. First, we describe and discuss two types that would provide access to information on the patented inventions: the information clearing house and the technology exchange clearing house. Second, three types of clearing houses are analysed that not only offer access to information but also provide an instrument to facilitate the use of the patented inventions: the open access clearing house, the standardized licences clearing house and the royalty collection clearing house. A royalty collection clearing house for genetic diagnostic testing would be the most comprehensive as it would serve several functions: identifying patents and patent claims essential to diagnostic testing, matching licensees with licensors, developing and supplying standardized licences, collecting royalties, monitoring whether users respect licensing conditions, and providing dispute resolution services such as mediation and arbitration. In this way, it might function as an effective model for users to facilitate access to and use of the patented inventions. However, it remains to be seen whether patent holders with a strong patent portfolio will be convinced by the advantages of the royalty collection clearing house and be willing to participate.},

In addition, this Essay shows that perfect control of propertized information--an animating assumption in much of the contemporary criticism--is both counterfactual and likely to remain so. These findings suggest that increasing the appropriability of information goods is likely to increase, rather than diminish, the quantity of "open" information.
