As IP Edge’s Litigation Pause Persists, Its Downward Pull on NPE Numbers Has Lessened

In the fourth quarter of 2023, NPEs added 442 defendants to patent litigation campaigns, or 17% less than Q4 2022—falling 28% short of the trailing three-quarter Q4 average, but exceeding Q3 2023 by 15%. This dropoff was less pronounced than in Q3, which saw over 30% less NPE litigation than the same quarter the year prior.

That narrowed gap was partly the result of the mere passage of time since the once-prolific monetization firm IP Edge LLC stopped filing new litigation after November 2022, largely the result of ongoing pressure over transparency in Delaware—and a resulting investigation into its business model by Chief Judge Colm F. Connolly. Since the firm filed no litigation in either December 2022 or December 2023, there was no IP Edge-related decrease during the latter month.

Meanwhile, operating companies added 283 defendants in Q4, a 19% increase compared to the fourth quarter last year. Operating company filings last quarter were 21% lower than in Q3 2023, though they exceeded the trailing Q4 average by 23%.

Overall, plaintiffs added 725 defendants to patent litigation campaigns in Q4, down by 6% from the same quarter one year prior, 2% less than Q3 2022, and 10% below the trailing average.
