Reassert the Strength of Your Patent’s Claims
An invalidity/validity search is an exhaustive, date-limited prior art search conducted against the claims of a patent to verify its validity or render it invalid by uncovering relevant art filed before its earliest priority date.
This type of search is conducted in order to challenge a patent using pre- or post-grant opposition options, or as a defence when facing a patent infringement lawsuit. An invalidity search also helps establish the strengths and weaknesses of a patent’s claims for fair licensing and acquisition negotiations.
Our Process
During an invalidity/validity search, our experts go through the file history of the patent in question and conduct a prior art search that takes into consideration the arguments raised by the examiner and the applicant/attorney.
We take a close look at the specific claims in the patent that need to be verified, consider the patent’s priority date, and target the prior art that is not listed on the face of the patent. Based on the results of our prior art search, and with the help of our search experts’ knowledge of patent laws, we aim to call into question the novelty or nonobviousness of the patent claim.
Common grounds for invalidating a patent include: prior public knowledge or use, or sale or publication of the product, process, or service before the priority date of the patent in question. Our team leaves no stone unturned and conducts thorough searches directed at each of these possible grounds.Once the search is concluded, we then provide an insightful, customer-friendly report that clearly maps out the prior art against the asserted claims. Our invalidity/validity search reports have been instrumental in overturning allegations of patent infringement and in helping clients take a stronger, better-informed stance in patent litigations or negotiations.
