Antitrust cases weren’t filed quite as frequently in 2023 as they were for most of the previous decade, but the 534 cases that were filed represent a year-over-year rise, the legal analytics company Lex Machina said Thursday in its annual antitrust litigation report.

The report showed that number is up 19% from 2022, but 2022 and 2023 were the two slowest years for antitrust filings in the last 10.
