MENLO PARK, Calif., May 19, 2022 /PRNewswire/ -- Lex Machina, a LexisNexis company, today releases its annual Patent Litigation Report. The report examines patent litigation trends in federal district and appellate courts, as well as the Patent Trial and Appeal Board (PTAB). It focuses on the three-year period from 2019 to 2021 and surveys emerging trends in case filings (including ANDA and PTAB case filings), active districts, judges, law firms, parties, timing metrics, case resolutions, findings, and damages. This is the first report to showcase the newest federal appellate analytics and trends in patent litigation in the federal courts of appeals.

"The increasing role of Judge Albright and the Western District of Texas in patent litigation is a major topic of discussion among litigators," said Elaine Chow, Lex Machina's patent legal data expert and author of the report.

It becomes possible to understand and anticipate evolving patterns in patent litigation."
