Duane Morris LLP Ranked Among Top Patent Trial and Appeal Board Law Firms

May 17, 2017

PHILADELPHIA, May 17, 2017—Duane Morris LLP has been ranked as the nation’s second most successful law firm among those representing petitioners before the Patent Trial and Appeal Board (PTAB). The institutional success index (ISIX) scoring mechanism, devised by IP service Unified Patents, ranks the top firms representing both petitioners and patent owners. The score is based on a firm’s success in getting reviews instituted and having at least one claim in a patent invalidated. A firm receives one point for any successful institution, but loses one for a non-institution, and drops two points for any final written decision in which all of the challenged claims are found patentable.

Created in 2012, the PTAB serves as an administrative law body of the United States Patent and Trademark Office (USPTO). The Board has become an important forum for patent cases, conducting trials, including inter partes, post-grant, and covered business method patent reviews and derivation proceedings, hearing appeals from adverse examiner decisions in patent applications and reexamination proceedings, and rendering decisions in interferences.

Inter partes review (IPR) is a popular procedure for adjudicating patent validity, and the ISIX rankings place Duane Morris among the best at winning these proceedings. Introduced by the America Invents Act (AIA) in 2012, IPR allows a petitioner to challenge the validity of a patent claim after a patent has been granted by the USPTO. Duane Morris attorneys advise clients on the merits and desirability of instituting proceedings before the USPTO, and also has substantial experience defending patents on behalf of patent owners during these proceedings. The firm has established a group focused specifically on IPR practice, comprising attorneys with the extensive procedural, technical and litigation experience, as well as oral advocacy skills, required to manage the challenges of this specialized area of intellectual property law.
