In the first six months of 2025 – as Unified had flagged last quarter – discretionary denials increased sharply at the PTAB, the result of changes by USPTO Acting Director Coke Morgan Stewart to the PTAB’s rules and procedures for evaluating inter partes review (IPR) and post-grant review (PGR) petitions. These changes include a bifurcated process for deciding whether to institute an IPR or PGR, emphasizing director discretion, and the expansion of the considerations for discretionary denial, including the reinstatement of the Fintiv factors and several new factors, including “settled expectations,” compelling public interests, and the extent to which the petition relies upon expert testimony.
In the federal district courts, the Eastern District of Texas remains the predominant venue for patent case filings, followed by the Western District of Texas and the District of Delaware. The E.D.Tex. continues to be the most popular venue for NPEs.
Additionally, requests for ex parte reexamination are currently on pace to match 2024’s level.
Key takeaways:
Based on the first six months of 2025, PTAB, ex parte reexamination, and district court filings are currently on pace to slightly exceed 2024’s numbers.
The W.D.Tex is increasing in popularity. Last year, it was the fourth most popular venue for patent filings and the second most popular for NPE filings; it is currently the second most popular venue for patent filings and NPE patent filings.
Combined, the Eastern and Western Districts of Texas accounted for 40% of all patent cases filed in the first six months of 2025 and 63.7% of all NPE cases filed during the same time period.
It remains to be seen how the increase in discretionary denials at the PTAB and the new bifurcated process emphasizing director discretion for determining institution on the merits will affect the number of IPR and PGR petitions filed in the rest of 2025.
In the Unified Patent Court, the number of infringement actions filed in the first six months of 2025 are projected to match 2024’s total.
Procedural Denials in PTAB Increase: The PTAB has issued 45% more procedural denials in the first six months of 2025 than it did in the entire year of 2024, and is well on pace to be one of the highest years on record. In June 2025 alone, the PTAB issued 75 procedural denials, an all-time high.
