IPR (Inter Partes Review)

Inter Partes Review (IPR) is a legal process used to challenge the validity of a patent after it has been granted. It allows a third party to request the Patent Trial and Appeal Board (PTAB) to re-examine the patent’s claims based on existing prior art—previous inventions, publications, or disclosures that could render the patent invalid. IPR provides a streamlined, cost-effective way to dispute patents, promoting innovation and competition by ensuring only truly novel inventions are protected. The process is an alternative to traditional court litigation and aims to resolve patent validity issues efficiently.
