==Definitions==<pdf>File:McN-PatentThicket-Egan-092215.pdf</pdf>
A) '''Saturated Invention Spaces:''' The earliest definition of a patent thicket that we found is in Teece (1998), who points out a simple issue with patents. We refer to this as ‘saturated invention spaces’ and describe it as when a single firm, or a small number of firms, successfully patents an entire technological area. (p.15)* '''''Coordination: Imperfect competition: a small number of firms hold all possible patent rights in an area'''''==Codification==
Terms like “cluster”, “related”, “adjacent”, or “coherent group” to describe either patents or inventionsSee the [[Patent Thicket Strategic Planning]] page for future steps. However, we also included several definitions that described patents as “minor” or “marginal” provided that there was no suggestion of bad faith
B) '''Diversely-held Complimentary Inputs (DHCI):''' 1) products require complementary patented inputs; 2) these inputs are diversely-held (i.e. held by N patent-holders); and 3) patent-holders set their license prices independently. (Shapiro, pg.17)* '''''Coordination: patent holders determine licensing rates independently'''''See the [[PTLR Codification]] page for details
“Diversely-held” and “complementary inputs,” or clear synonyms like “dispersed” or “fragmented” pertaining to ownership and “Cournot problem”, “multiple marginalization”, etc. in See the context of licensing of patents held by multiple parties[[PTLR Process]] page for details
C) '''Overlapping Patents:'''#The second most common foundation for a patent thicket issue relies on overlapping patents. Patent overlaps can be horizontal (i.e. though patents that are largely adjacent to one another) or vertical (i.e. when patents are related through cumulative innovation). Horizontal overlaps arise because patent rights are imperfectly defined property rights. (p.20)#Refinement patents and research tool patents could result in vertically overlapping patent rights (or at least contractual rights). (p.21)* '''''Imperfectly defined property rights: wasteful duplication of licensing expenditure'''''==Test Run==
Any sense of patent overlaps including “overlapping claims” or “similar claims”, and/or uncertainty over whether multiple patents may simultaneously be infringed D) '''Gaming the Patent SystemExample BibTeX:''' There are information asymmetries between a patent applicant and the patent office and a patent applicant may take some inappropriate action, for example by applying for a patent that is not novel or is obvious. Such an inappropriate action can impose costs on the patent office and may generate negative externalities, imposing costs on genuine innovators. We refer to this situation as ‘gaming the patent system’. (p.21)*'''''Imperfect competition: a small number of firms hold all possible patent rights in an area''''' Primarily descriptions of patents as “questionable” “dubious” “bad”, “likely invalid” and “junk,” and phrases congruent with “impeding genuine innovators” or “rent-seeking activities”, as well as other indications of bad faith ====Modern Terms==== E) '''Transaction Costs:''' Patent applications are subject to transaction costs in the form of prosecution costs and renewal (‘maintenance’) fees. These costs and fees are supposed to de-incentivize low value patents. However, they may also de-incentivize invention by small firms and individuals. (p.13) F) '''Probabilistic Patents:''' Lemley and Shapiro (2005, 2006) emphasize that patents are ‘probabilistic’. They suggest that “there is no way to determine with certainty whether the patent is valid and infringed without litigating to judgment." Enforcement of patent rights - observing and redressing infringement of patent claims - is therefore both costly and uncertainty. (p.11) G) '''Unspecified/Extended Use:''' Kiley (1992) claims that applying for a patent based on an inventive step that does not have a clearly articulated stand-alone commercial value creates economic inefficiencies. But often it can be difficult to foresee which particular use of an invention will be profitable and which won’t. (p.8)

==Latest Progress==
The PDF-to-Text converter, the key terms finder, and phrase extraction scripts all work well and have been tested. The Google Scholar Web Crawler is being worked on by Christy Warden, current status unknown.
192 text versions of papers have been assembled in "Candidate Papers by LB." These were used as a test set for developing an analysis protocol for the entire paper. An analysis protocol has been developed that involves taking the counts of each term by topic per paper to assign each paper 1-4 topics. The process also counts the number of key terms in each paper for relevance, the number of modern terms, the year of the paper, the number of cost terms, the area of the paper, and the mentions of particular authors. All of this analysis is then dumped into artifacts. The analysis protocol is currently hardcoded. Once a set list of terms has been established, a soft-coded version should be able to be developed (in progress).
Larger test set desired to be analyzed and soft-coded on.
