Patent typically includes Drawings suitable for filing, Legal and Technical specification and all necessary Formal Papers required for filing by the U.S. Patent Office in order to achieve a Patent Pending status as stated in https://www.techtimes.com/articles/249715/20200518/how-inventhelp-gets-new-inventors-onto-the-right-path.htm article.
6 to 8 Weeks After Filing
The first official action sent to you is a filing receipt; date, application number, art group, name of applicant and title of invention. It will also give you the preliminary class number as well as the status of “Foreign Filing License” with an explanation on the back portion of the receipt.
Approximately 6 to 12 Months After Filing
The typical next step, if necessary, would be to receive an “Office Action.” This is when the Patent & Trademark Office (PTO) states that other known art was found in their patent search. The PTO can make objections, request clarification and point out obviousness concerning your patent application.
Approximately 6 to 18+ Months After Filing
If no other office actions are received, you will obtain either a “Final Notice” or “Notice of Allowance.” If not already submitted, you must submit formal drawings to the PTO along with the required issuance fee. After satisfying this fee, you will receive an “Issue Notification” in approximately four to six weeks; your final patent will be sent in about three to five day from the date listed on you issue notification.
