The PTAB has an all-claims invalidation rate of 70%, which has raised alarm within patent circles. This rate reflects the percentage of challenged claims deemed invalid during inter partes reviews (IPRs). Over time, this invalidation rate has varied, growing from 55% in 2019 to 70% in 2024. Recent statistics from FY2025 show a slight decrease to 64%, still indicating a problematic situation. In contrast, the invalidation rates for ex parte reexamination are much lower, indicating a difference in how validity is assessed across different processes.
The PTAB's 70% all-claims invalidation rate indicates that when a patent is subjected to an IPR, a significant percentage of challenged claims are found invalid.
The all-claims invalidation rate has fluctuated over the years, increasing from 55% in 2019 to 70% in 2024, highlighting ongoing concerns about patent validity.
Despite a decrease to 64% in FY2025, the PTAB's all-claims invalidation rate remains high, raising questions about the reasons behind such a trend.
The lower invalidation rates in ex parte reexamination by the USPTO suggest contrasting approaches to patent claims validation compared to inter partes reviews.
