Patent Studies by John Allison

John R. Allison, Mark A. Lemley & Kimberly A. Moore, Valuable Patents. Forthcoming 2003, Georgetown Law Journal. This study draws from the 1996-98 Allison-Lemley patent data and Prof. Moore’s data on patent litigation, plus additional data that I generated from (a) the original 96-98 set, (b) over 300 patents randomly selected from approximately 1,200 that were in litigation that terminated in 1999 and 2000 (that had been issued during 1996-98 time period), and (c) a National Bureau of Economic Research database containing certain data from almost 3 million patents. We found that patents that become involved in infringement litigation are far more valuable than those that do not.

John R. Allison & Emerson H. Tiller (MSIS Dept.), Statistical Analysis of Internet Business Method Patents, Final Statistical Findings (Oct. 22, 2001). I identified over 2,800 patents issued through 1999 using an over-inclusive Lexis search, studied all of them multiple times, and produced a data set of 1,093 Internet-related business method patents. I extracted an enormous amount of data from these patents dealing with essentially all measurable characteristics of patents. Bivariate and multivariate analyses were used for comparisons within this data set for different types of Internet patents and, with data on patents-in-general from the published Allison & Lemley study of 1996-98 patents. Emerson Tiller and I received one of 7 grants (out of 75 proposals nationwide) from the National Academy of Sciences’ Board on Science, Technology, and Economic Policy (STEP). We presented our findings at NAS on Oct 22, 2001, and a 104-page final report in December 2001.

John R. Allison & Mark A. Lemley (UC-Berkeley), The Growing Complexity of the United States Patent System 82 BOSTON UNIVERSITY LAW REVIEW 77-144 (2002). This statistical study compares the results of the published study reported immediately below based on the 1996-98 patent data set with results from a comparable study of 1,000 randomly selected patents from 1976-1978, resulting in findings demonstrating how and why the patent system has grown far more complex in many dimensions over a 20-year period.

An Empirical Exploration of Patent Prosecution (with Mark Lemley, Univ. of Cal.-Berkeley Law School), 53 VANDERBILT LAW REVIEW 2099-2174 (2000). This is a statistical analysis of 1,000 randomly selected patents issued during 1996-98, examining evidence of relationships among areas of technology, country of inventions origin, and numerous variables in the patents). This study was assisted by a grant from the McCombs School in summer 1999.
