Osha Liang has experience preparing and arguing appeals before the Patent and Trial Appeal Board (PTAB) in all technical disciplines. Drawing on experience from prosecution and litigation, the Appellate Practice Group uses a combined approach of technical and legal analysis to advocate on behalf of our clients. The Appellate Practice Group also reviews PTAB decisions in order to determine trends from the judges that might further enhance our client’s success on appeal. Significant and/or influential opinions from the PTAB that might impact appeals practice, as well as prosecution in general, can be found on the PTAB Review page.
