FAQs Patent Questions
Question:Can I obtain international patent protection for my invention?
Answer: Since the rights granted by a U.S. patent extend only throughout the territory of the United States and have no effect in a foreign country, an inventor who wishes patent protection in other countries must apply for a patent in each of the other countries or in regional patent offices.
Question:Is it necessary to go to the USPTO to transact business concerning patent matters?
Answer:
No. Most business with the Office is conducted by written correspondence. Interviews regarding pending applications can be arranged with examiners if necessary and are often helpful.
Question:The Official Gazette contains information on Expired patents, Patents reinstated and Reissue Applications
Answer:
No. The Official Gazette contains a section at the front of the book called "Patent and Trademark Office Notices." Each week, the following information is published: a. Expired Patents: Patents that expire due to failure to pay required maintenance fees. These patent numbers are published approximately 3 months after expiration. b. Patents Reinstated: Patents reinstated due to the acceptance of a late maintenance fee. c. Reissue Applications: Patents filed as reissues. d. Reexams: Patents requested to be reexamined. e. Certificates of Correction: Patents granted certificates to correct previously published material. f. Summaries of final decisions issued by the Trademark Trial and Appeal Board.
