Intellectual Asset Management writes "One of the standout US patent trends from last year, at least in terms of disputes, was the drop in new petition filings at the Patent Trial and Appeal Board (PTAB). Overall, according to Lex Machina, the number of post-issuance proceedings fell from 1,720  to 1,322, with the number of new inter partes reviews decreasing to 1,271 from 1,608 in 2018."

After a "stellar" performance in 2018, Intellectual Asset Management highlights the continued prevalence of Sterne, Kessler, Goldstein & Fox P.L.L.C. at the Patent Trial and Appeal Board (PTAB). Despite a 2019 drop in new filings at the PTAB, Sterne Kessler ranked first in the top 20 firms acting for patent owners, second overall, and third by the number of cases handled for petitioners.
