Litigation Support - Invalidity Contention Report

Invalidation proceedings may be initiated against a patent for a variety of reasons. For example, in a patent infringement case, the alleged infringer of a patent may desire to show that the patent-in-suit is invalid or unenforceable. A person/ company may also want to invalidate a patent if the patent can cause loss of freedom to operate. As all patents are entitled to a presumption of validity, it is necessary to demonstrate invalidity by clear and convincing evidence. These evidences may include patent as well as non-patent literature.

We at Anindus can prepare invalidity contentions where we search for and map prior art against the claims of a patent to provide evidence for invalidating the patent.

We also have a team trained in providing a response to invalidity contentions by identifying the differences between the patent under contention and the prior art cited by the opponent, in a format as desired by the client.
