Post-grant review

Post-grant review is a legal process that allows interested parties to challenge the validity of a patent after it has been granted. Typically initiated within a specific time frame, it provides a formal procedure to argue that the patent should not have been issued, often due to issues like lack of novelty or obviousness. This process helps ensure that only valid patents remain enforceable, maintaining fairness in innovation and competition. It is a more efficient alternative to traditional court litigation, providing a way to scrutinize patents through an administrative review.
