Unified Patents has performed an analysis of data aggregated from the Patent Trial and Appeal Board (PTAB) and ranked White & Case the Number 1 US law firm for institutional success in inter partes review (IPR) petitions. White & Case's top position appears in Unified Patents' Institutional Success Index (ISIX) – Petitioner Law Firm.
The ISIX shows US law firms' success rate at getting reviews instituted and having at least one claim in a patent invalidated. The analysis omits firms with fewer than 50 decisions.
White & Case's top ranking was highlighted in a blog entry on IP business media platform IAM: "White & Case and Fitch Even revealed as the top law firms at the PTAB, according to new research."
