The District of Delaware remained one of the country’s top venues for patent cases in 2020, despite case filings decreasing from the previous year, Lex Machina found in its annual patent litigation report, released Thursday.

COVID-related restrictions, a drop in Abbreviated New Drug Application filings and plaintiffs’ strategizing on where and how frequently to file all played a role in Delaware seeing 26% fewer patent filings in 2020 and losing its place as the top venue for patent litigation to the Western District of Texas, said Geneva Clark, a Lex Machina legal data expert and the author of the report.
