Patent Validity / Invalidity Search

An Invalidity Search, also known as a Validity Search, is an extensive investigation conducted post-patent grant. This search aims to identify patent and non-patent literature filed or published before the earliest priority date of the subject patent. It serves as a foundational step for legal opinions on infringement or as due diligence before patent licensing, acquisition, or sale.
