Post-Grant Proceedings | McDermott IP Lawyers

Post-Grant Proceedings


Our team of business-savvy intellectual property (IP) lawyers can guide you through the complex web of administrative practices and trial procedures involved in Patent Trial & Appeal Board (PTAB) proceedings to protect and enforce your patents and structure the strongest possible case on your behalf. Whether you are involved in an inter partes review (IPR), post-grant review (PGR), covered business method review (CBM) or ex parte reexamination (EPR), the complex nature of these proceedings can make them difficult to navigate.

Proceedings before the PTAB are an effective strategy in combination with—or instead of—traditional litigation. We understand the necessary policies and procedures at the PTAB, and we fight fearlessly and relentlessly for our clients. That includes developing trial strategies that take into account any parallel district court litigation, US International Trade Commission (ITC) actions or appeals before the US Court of Appeals for the Federal Circuit.
