An invalidity search is a comprehensive review conducted to determine whether a patented invention is valid or if prior art exists that could invalidate the patent. This search typically examines existing patents, scientific literature, and other public disclosures prior to the patent filing date. It helps identify potential weaknesses in a patent�s claims, which can be crucial for legal challenges, litigation, or strategic business decisions. By assessing the novelty and non-obviousness of the patented invention, an invalidity search provides essential insights for stakeholders.
An invalidity or opposition search is to identify patent and patent documents which may impact the claims of a specific patent. This can help block patents and establish solidity of a patent portfolio which may be useful for licensing or company acquisition.
“Impact the claims”- means challenge the novelty and inventiveness (i.e. demonstrate obviousness) of the claims of the patent.
