Patent Validation / Invalidation Search patent-art.com

Patent invalidation is the process of challenging and ultimately cancelling the legal validity of a granted patent. This can be done for various reasons such as prior art, lack of novelty, obviousness, lack of utility, or noncompliance with formal requirements. Invalidation proceedings can be initiated by a third party or by the patent owner themselves and can take place in a court of law or in front of a patent office.
