Question

what is the main purpose of a provisional patent??

Answer 1

Solution:-Here provisional patent is a legal document oriented filled application.The main purpose of a provisional patent is a quick and inexpensive way for inventors to establish a U.S. filing date for their invention. Provisional application is a legal document filed in the United States Patent and Trademark Office(USPTO), that establishes an early filing date, but does not mature into an issued patent unless the applicant files a regular non-provisional patent application within one year. There is no such thing as a "provisional patent. A provisional application can establish an early effective filing date in one or more continuing patent applications later claiming the priority date of an invention disclosed in earlier provisional applications by one or more of the same inventors.A provisional application includes a specification, i.e. a description, and drawing(s) of an invention (drawings are required where necessary for the understanding of the subject matter sought to be patented), but does not require formal patent claims, inventors' oaths or declarations, or any information disclosure statement (IDS). Furthermore, because no examination of the patentability of the application in view of the prior art is performed, the USPTO fee for filing a provisional patent application is significantly lower than the fee required to file a standard non-provisional patent application.
