A recent report from patent data powerhouse RPX Corp. shows that
inter partes review (IPR) filings have increased significantly over
the last three quarters, pointing to increased litigation over the
last year. One possible driving factor? Non-practicing entity
litigation, which increased by 24% in Q1 2024 alone, according to
RPX. As noted in Foley’s recent PTAB Year in Review, 2024
promises to be a year filled with exciting developments at the
PTAB, and the substantial increase in IPR filings will be a further
catalyst for change.
The Patent Trial and Appeal Board (PTAB) saw 328 petitions for
America Invents Act (AIA) review in the first quarter of 2024,
including 322 petitions for inter partes review (IPR) and six
petitions for post-grant review (PGR). Filings were down by 5%
compared to Q1 2023, which saw 345 petitions filed; but were up by
18% compared to Q4, during which 278 petitions were filed.
