Summary

Decisions about what an international patent application that names the United States covers, and how to handle its process, will be made the same way as for regular U.S. patent applications filed at the Patent and Trademark Office, as allowed by the treaty and Office rules. If the international application names the U.S. but did not originate here, the Director may recheck the application’s form and content under the treaty and rules; may reexamine unity of invention under section 121 within those limits; and may require verification of a translation if any part was filed in a language other than English.
