PTLR Core Papers

• This page is referenced in the Patent Thicket Literature Review

This page details the 'Core' papers of the Patent Thicket Literature Review (PTLR). A paper is 'core' if it explicitly models or studies patent thickets.

Pages containing previous versions of papers are indented below their subsequent version. Write-ups will only be done for the subsequent versions. The BibTex entries for these papers are available as a list on the PTLR Core Group Processed BibTeX page, and each paper page has its own BibTeX entry in its reference section.

Non-Core Papers

The following papers do not explicitly discuss patent thickets but are vital to an understanding of thickets or their measures:

1. Hall (2005) - A Note On The Bias In Herfindahl Type Measures Based On Count Data

The following papers were erroneously classified as core:

1. Cockburn Wagner (2007) - Patents And The Survival Of Internet Related Ipos

Paper Origins

The vast major of these papers were contained in the first download. However, the following four papers were found during the convergence process:

1. Merges (1999) - Institutions For Intellectual Property Transactions
2. Merges Nelson (1990) - On The Complex Economics Of Patent Scope
3. Murray Stern (2007) - Do Formal Intellectual Property Rights Hinder The Free Flow Of Scientific Knowledge
4. Walsh Arora Cohen (2003) - Effects Of Research Tool Patents And Licensing On Biomedical Innovation

And the following paper was added as it was referenced in the review done by Kirti Gupta, deemed to be directly about thickets, and we didn't have it:

1. Epstein Kuhlik (2004) - Is There A Biomedical Anticommons
