What is Patent Filing?
A legal document Filed under United States Patent Law in The United States Patent and Trademark office (UPSTO) is called Provisional application. Provisional application establishes an early filing date, but does not mature into an issued patent. For that an applicant has to file a regular non-provisional patent application within one year. Thing as a Provisional Patent does not exit.
It includes a specification but does not require formal Patent claims, inventors’ declarations or oaths or any IDS (Information Disclosure Statement). By filling the application, it will establish an early effective filing date in one or more continuing patent application later claiming the priority date of an invention disclosed in earlier provisional applications by one or more of the same inventors.
