Q1 2021 Patent Dispute Report

Overview

The one lesson learned in 2020 is that not even a pandemic can stop patent litigation. This again is proving to be true as the world starts the recovery process, patent disputes have not skipped a beat. In fact, the first quarters numbers are in-line with the previous of 1,256 combined patent litigation and PTAB disputes. While litigation remains high, the PTAB appears to be taking a 7% decrease versus last year. This is partially due to the fact more companies are using the re-examination process due to the uncertainty of discretionary denials. 

Highlights:

  • Western District of Texas now accounts for 25% of all patent disputes, with NPE-related litigation out pacing any other jurisdiction. 

  • NPE-related litigation appears to be on track with a projected 2,336 cases, which is a 1.75% increase from last year.

  • Samsung, again, is the most prolific PTAB filer (49 filings) and at the same time are the most targeted defendant in patent litigation (19 cases as first-named defendant).

  • Ericsson was the most attacked patent owner at the PTAB with 30 petitions filed against them. 

  • Unified, still remains the 5th overall filer with 226 and has expanded its efforts with 9 re-examinations and 8 Chinese oppositions this year. In addition, last year Unified also filed 6 EPO oppositions, 1 UK opposition and 2 Japanese oppositions from last year.

Figure 1: If the first quarter is any indication of how 2021 will play out, patent litigation in general appears to be matching the previous plateau trend from the past few years. Interestingly, it would appear that PTAB activity will also be down this year, possibly due to companies taking advantage of Re-Exams with the uncertainty of the discretionary denials.
