'''Elimination of Competition''' Opponents criticize patent pools for the potential of anti-competitive behavior and collusion, primarily with regards to substitute patents. Substitute patents cover competing technologies that can be developed in parallel without risk of infringement [http://www.wipo.int/export/sites/www/ip-competition/en/studies/patent_pools_report.pdf]. Patent pools formed between entities holding substitute patents eliminate competition in that particular technological sector, reinforcing the parallels drawn between patent pools and cartels [http://www.wipo.int/export/sites/www/ip-competition/en/studies/patent_pools_report.pdf (WIPO)]. Patent pools potentially create a way for companies to share competitively sensitive information, such as pricing, marketing strategies, or R&D information among its members." [http://www.wipo.int/export/sites/www/ip-competition/en/studies/patent_pools_report.pdf (WIPO)] For example, R&D information and developments could be shared in grant-back provisions, a requirement that companies share new or downstream technologies and innovations with members of the pool without additional fees.
