Due to the enactment of the America Invents Act on September 16, 2011, the USPTO now has two separate forms pages, one page containing forms for patent applications filed on or after September 16, 2012, and one containing forms for patent applications filed before September 16, 2012. Please click the appropriate hyperlink below to access the applicable patent forms for your patent application.
Please note the following:
- Some forms may appear on both pages.
- For patent applications filed under 35 U.S.C. 111(a), the actual filing date, and not an earlier effective filing date based on one more more domestic benefit claims, is used to determine which forms should be used.
- For applications entering the national stage under 35 U.S.C. 371, the international filing date of the international application is used to determine which forms should be used.
