The number of patent cases filed in federal court jumped up in 2015, and the Eastern District of Texas emerged as the single most popular place to file cases by a large margin, according to a report scheduled for release on Wednesday.
Issued by data analytics company Lex Machina, the report looks at intellectual property litigation in U.S. District Courts, using data mined from PACER, the federal courts database.
The report found there were 5,819 total patent cases filed in 2015. That’s up 14.7 percent from 5,070 in 2014 but still lower than the previous high of 6,113 in 2013.
