Copyright filings declined significantly over the last two years, according to a new report by Lex Machina, which found that overall cases had dipped from a 2018 peak that was driven primarily by surges in file-sharing litigation.

According to the report, there were 5,031 and 3,485 new copyright cases filed in 2019 and 2020, respectively, down from a high of 6,536 three years ago.

File-sharing cases, which accounted for 41% of all copyright filings from 2018 to 2020, involve infringement claims brought against anonymous John Doe defendants or IP addresses and often tend to be filed in droves, according to the report.
