This document discusses different types of prior art searches including patentability searches, validity searches, freedom-to-operate (FTO) searches, and state-of-the-art searches. It explains that a prior art search aims to identify any publicly available information, publications, or knowledge that existed before the filing date of a patent application. The document outlines when each type of search is typically conducted, the scope and focus of each search, and whether patent or non-patent literature is searched. It also provides a brief overview of how prior art searches can help inventors, companies, and patent holders by avoiding infringement, strengthening patent applications and defenses, and keeping up with competition and technology developments.
