Lex Machina, a provider of patent litigation data and analytics, released “Lex Machina 2013 Patent Litigation Year in Review” today. The free report is the first of a series of annual reports on U.S. patent litigation, according to Owen Byrd, the company’s chief evangelist and general counsel.

The report draws on public data obtained from U.S. federal courts (PACER, or Public Access to Court Electronic Records) and the International Trade Commission (EDIS, or Electronic Document Information System), analyzed using Lex Machina’s Legal Analytics, and reported on the company’s Web application.
