The prosecution history refers to the comprehensive documentation of all events that occurred during the application process for a patent or trademark, starting from the initial submission until its approval. This encompasses all the correspondence, documents, and exchanges between the applicant and the Patent and Trademark Office. It is also known as the file history or file wrapper. A file-wrapper continuation occurs when additional information is added to the file history subsequent to the initial application.
The prosecution history encompasses the entire set of proceedings that occur in the Patent and Trademark Office, starting from the initial application and concluding with the issuance of a patent or registration of a trademark. This comprises all forms of documentation, correspondence, and other records of the proceedings that took place before the PTO regarding the application. For instance, if an individual files for a patent, the prosecution history would comprise all the documents and correspondence exchanged between the applicant and the Patent and Trademark Office, as well as any decisions or actions taken by the PTO concerning the application. The prosecution history holds significance as it can be utilised to interpret the scope and meaning of the claims made in the patent or trademark. It can also be employed to determine the legality of the patent or trademark in legal disputes.
