Overview

A new venue is beginning to emerge this quarter for NPEs as they continue their assault on the High-Tech sector. Over the past few years, filings for both the District Court and PTAB proceedings have steadily declined but are now beginning to level off.

Highlights:

While Delaware is a preferred venue for patent litigation outside of the PTAB, the Western District of Texas has not only become a hotbed for patent litigation, but a preferred venue for NPEs. The Western District of Texas is on pace to have over 600 patent related cases, which NPEs comprise 80% of all cases. This is partly due to Judge Alan D. Albright, a former patent litigator appointed to the bench.
Filings for both PTAB and District Court appear to be leveling off, with a similar amount of cases as compared to last year.
Small-to-medium enterprises (SME) made up 32% (270 cases) of all patent litigation defendants, primarily sued by NPEs, and were responsible for less than 10 of all Q1 PTAB challenges.
NPEs continue to bring the most patent disputes in the High-Tech sector for both District Court and PTAB proceedings. NPEs accounted for 85% of patent assertions in District Court and were responsible for 68% of all PTAB proceedings in the High-Tech Sector.

Figure 1: Assuming current trends continue, 2020 disputes are expected to be nearly the same as last year. View all District Court and PTAB litigation on Unified’s Portal.

Figure 2: The quarter-by-quarter analysis shows a decline in both PTAB and District Court filings. As mentioned above, Q1 saw 841 District Court filings and 329 PTAB filings compared to 799 District Courting filings and 340 PTAB filings in Q1 of 2019. Again, this illustrates that filings for both PTAB and District remain flat since Q3 of 2017. View all District Court and PTAB litigation on Unified’s Portal.

Figure 3: Although the PTAB remains the most popular venue for patent disputes overall, the Western District of Texas has become the most popular venue for NPEs in 2020. On the other hand, the District of Delaware had more filings by both NPEs and operating companies combined. View all District Court litigation on Unified’s Portal.

Figure 4: Assuming this trend continues in the Western District of Texas, the venue will have increased 700% in the last 4 years to become almost equal in patent cases (632) as the District of Delaware (696). View all District Court litigation on Unified’s Portal.

Methodology

This report includes all District Court and PTAB litigations between January 1, 2015 and March 31, 2020.

Total number of reported cases can vary based on what is included. Unified made its best attempt to eliminate mistaken, duplicative, or changes in venue filings, hence the totals may vary slightly compared to other reporting entities. Statistics include litigations initiated by NPEs or Declaratory Judgments (DJs) initiated by operating companies against NPEs.

Unified strives to accurately identify NPEs through all available means, such as court filings, public documents, and product documentation.
