The term "prosecution history" refers to the entire record of the prosecution of a patent, trademark or copyright application. There are several synonyms for this term, including "file wrapper," "prosecution file," or "prosecution record." Regardless of which term is used, they all refer to the same thing - the complete history of a legal proceeding. This history can include everything from initial filings to final decisions to any amendments, arguments, or decisions made along the way. Understanding the prosecution history is important in evaluating the strength of a patent or other intellectual property protection as it can shed light on the claims and their scope.
