Post-Grant Review (PGR)
Post-Grant Review: A Broader Approach to Patent Challenges
Post-Grant Review (PGR) offers an extensive process for challenging newly issued patents within nine months of their grant. PGR allows petitioners to argue that a patent is invalid based on a wider range of issues than Inter Partes Review (IPR) and Ex Parte Reexam, including indefiniteness, lack of enablement, and unpatentable subject matter. Collier Legal’s patent attorneys provide skilled representation in PGR cases, leveraging our deep understanding of PTAB procedures to build strong, evidence-backed cases for our clients.
During PGR proceedings, our attorneys carefully review the patent’s claims and investigate any issues that may impact its validity. We work with experts to gather comprehensive evidence, draft persuasive petitions, and provide representation during hearings.
Common Issues for PGR Proceedings
- Enablement and Written Description – Arguing lack of sufficient description.
- Indefiniteness – Highlighting unclear or vague claims.
- Patentable Subject Matter – Challenging claims that cover unpatentable subject matter.
