FAQs Patent Questions
Question:What is the Official Gazette?
The Official Gazette of the United States Patent and Trademark Office for Patents (OG) is issued every Tuesday and summarizes that week's patented inventions.
Question:How are patents accessible in the Electronic Official Gazette - Patents?
Patents are accessible by patent number, classification, a range of classes, patent type, and patentee name. There are also indexes by geographic location of the inventor, both by state and country.
Question:Can I obtain international patent protection for my invention?
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.
