PTAB Post-Issuance Proceedings


At Haug Partners, we have a wide range of experience representing clients in matters before the Patent Trial and Appeal Board (PTAB), including proceedings such as post-grant reviews, inter partes reviews(IPR), and covered business method reviews. Our PTAB Post-Issuance Proceedings team includes attorneys and scientific advisors with advanced degrees in specialized technical fields and hands-on industry experience. Many of our attorneys and advisors are licensed to practice before the U.S. Patent and Trademark Office, and our team includes a former PTAB Lead Trial Judge who has presided over nearly two hundred post-grant trials, including interlocutory discovery and motion proceedings, and authored more than sixty substantive decisions. Our PTAB Post-Issuance Proceedings team regularly represents sophisticated global companies as both petitioners and patent owners in critical IPRs, and consistently achieves exceptional results for our clients due to our proficiency in patent law and our understanding of the nuances of PTAB procedure. We are experienced in the challenges of simultaneously navigating a PTAB post-issuance proceeding alongside a pending district court litigation. We pride ourselves on our effective representation of our clients across a wide range of industries, including pharmaceutical, biotechnology, automotive, medical device, computer science and software, and mechanical and electrical device.
