This page and its sub pages provide the raw materials and derived 'data' for a literature review on patent thickets.
##The Down group consists of 47 papers that underpin the thicket literature while not explicitly discussing thickets. This group includes theory models for complementary or substitute innovations, for sequential innovation, for 'probabilistic patents', or for patent races, discussions of the relative importance of various aspects of intellectual property (such confering rents vs. providing information), and econometric papers on the use of patent statistics.
##The Up group consists of 97 papers that use patent thickets in some fashion. This group essentially takes patent thickets as given and builds from there. This groups consists of papers concerning mechansisms for addressing the consequences of thickets, such as Pools, SSOs and Standardization, Licensing arrangements, Trolls, Clearance Houses, Joint Ventures, and so forth; papers on IPR Reform, which advocate changes to patent policy, antitrust policy, the Bayh-Dole Act, etc.; papers on firm strategy, which includes strategic responses to thickets, the effects of thickets on portfolio values, and other advocation of firm-level responses; and a considerable amount of industry specific commentary. This last category generally overlaps with the others - for examples there are papers written for genome researchers informing them of the consequences of thickets in thier area, or that patents on segments of the genome are either invalid or not blocking.
#45 of the 59 Core papers could be 'ripped' to text files and were. The references from theses these files were then extracted in 41 instances. The remaining 4 papers were law papers with their references scattered in footnotes that could not be reliably extracted by computer software. The references for these 41 papers were then matched against on another to produce counts of the most cited papers within the core group. This process led to 313 papers that were cited by more than one paper in the core group. Of these 239 were not in the original sample of 251. Each of these 239 papers was briefly checked to see whether it should be added to the core group and 8 papers were added.
