Inter Partes Review (IPR)

Inter Partes Review: Challenging Patent Validity Through PTAB

Inter Partes Review (IPR) provides a pathway to challenge the validity of existing patent claims based on prior art. IPR allows third parties to file petitions within the PTAB to review and potentially invalidate patents, serving as a cost-effective alternative to lengthy patent litigation. Collier Legal represents clients in IPR proceedings, from petition preparation through to final decisions, ensuring that each argument is backed by a solid understanding of patent law.

During an IPR, we analyze the patent’s claims and identify prior art that may render the claims unpatentable. We assist with drafting detailed petitions, responding to oppositions, and, when necessary, representing clients during PTAB oral hearings. Our strategic approach is grounded in a deep understanding of patent prosecution and the nuances of prior art application.

Common Issues for IPR Proceedings

  • Prior Art Analysis – Identifying strong prior art to support the challenge.
  • Claim Construction – Arguing for a claim interpretation favorable to your position.
  • Amendment Requests – Handling requests to amend claims during IPR.
