The Key to Invalidity, Strength Analysis & Patent and Design Busting!
Have you been accused of violating a patent or concerned about an existing patent? Our invalidity search can help you determine if that patent is valid. This can provide valuable information to support your defense. If you are being targeted by a patent (accused of infringing a patent), this search (also known as a patent-busting search), can assist you in attempting to invalidate the patent.
Our search can also be used to evaluate the strength of your own patent before launching your product or enforcing your patent. It can also be used to assess the worth of a patent you are considering purchasing. (These searches are also referred to as Validity searches).
