Three-Year Rise in Patent Lawsuits
Table 1: Patent Civil Filings
The latest available data from the federal courts show that during January 2013 the government reported 530 new patent civil filings.
According to the case-by-case information
analyzed by the Transactional Records Access Clearinghouse (TRAC), this number
is up 46 percent over the same period one year ago, and is nearly two and a half times the level reported in January 2010 (up 147 percent).
Patent lawsuits are brought to enforce provisions of the Patent Laws under Title 35 of the U.S. Code
(35 U.S.C. 271,
35 U.S.C. 281 and
35 U.S.C. 145, among others)
as well as
28 U.S.C. 1338
and 15 U.S.C. 1126
and other statutes related to intellectual property protection.
The comparisons of the number of civil filings for patent-related suits are based on case-by-case court records which were compiled and analyzed by TRAC (see Table 1).

The long term trend in patent civil filings going back five years
is shown more clearly in Figure 1. The vertical bars in Figure 1
represent the number of patent civil filings recorded each
month. The superimposed line on the bars plots the six-month moving average so that natural
fluctuations are smoothed out.
One, three and five-year change comparisons are based upon the moving averages.
Top Ranked Judicial Districts
Relative to population, the volume of civil matters of this type filed in federal district courts during January 2013 was 1.7 per every million persons in the United States.
One year ago the relative number of filings was 1.2.
Understandably, there is great variation in the per capita number of patent civil filings in
each of the nation's ninety-four federal judicial districts.
