To register a trademark with the U.S. Patent and Trademark Office (USPTO), you will need to fill out and submit a trademark application. You can do this online, using the Trademark Electronic Application System (TEAS), an online trademark filing service, or you can submit a paper application.
One can go to the USPTO official website and file a patent online. Publication: The Patent Office publishes the application on their official website after some time. Then, the application is ready to enter for the examination stage. Prosecution: During examination, the examiner may ask for a few clarifications.
