Patent Validity Challenges

Irwin IP’s intellectual property litigators are experienced and well-versed in all aspects of intellectual property litigation, including pursuing and defending against patent validity challenges before the Patent Trial and Appeal Board such as Post-Grant Review, Covered Business Method Review.  Inter Partes Review (commonly known as “IPR”) proceedings, in particular, are a relatively recent, but rapidly growing, development in the field of intellectual property law, and provide an expedited and economical means to challenge the validity of a patent through review by the Patent Trial and Appeal Board (“PTAB”) outside of the narrow window of time afforded by the PGR proceeding.

Irwin IP has a proven track record of successful practice before the PTAB.  Recently, the PTAB instituted IPR proceedings based upon a petition prepared by Irwin IP attorneys against a patent that was not only touted by its Fortune 50 owner to be the foundation of a billion-dollar-per-year business, but had survived invalidity challenges in two prior litigations and an IPR action. Despite this substantial body of adverse history, the PTAB instituted IPR upon Irwin IP's client's petition, determining that there was at least a "reasonable likelihood that [Irwin IP's client] would prevail."

Irwin IP litigator’s knowledge of PTAB proceedings, as well as substantive patent law, allow them to design sound and successful strategies for clients’ intellectual property challenges using all of the tools in the intellectual property litigator’s toolbox, including proceedings challenging or defending patents before the PTAB.
