An ADS isn’t needed for a provisional patent application. You should fill out for SB/16, a provisional cover sheet and submit it with your application. Otherwise the intake people will send you a message for an incomplete submission and charge you extra money to fix it. Here’s a link to the USPTO’s forms page: https://www.uspto.gov/sites/defa... . If you have a digital certificate with the USPTO you can fill this form out online using the EFS Web (this is the preferred method, less likelihood of errors). If you need instructions on how to fill out the form, visit: Forms For Patent Applications Filed On Or After September 16, 2012 and search for SB/16. It has the link above for the form and a link for the instructions. Good luck.
