FAQs Patent Questions
Question:A Patentee who makes or sells patented articles is required to mark the articles with the word “Patent”
Answer: A patentee who makes or sells patented articles, or a person who does so for or under the patentee is required to mark the articles with the word “Patent” and the number of the patent. The penalty for failure to mark is that the patentee may not recover damages from an infringer unless the infringer was duly notified of the infringement and continued to infringe after the notice.
Question:How can I get Land Entry file information for patents?
Answer:
Land Entry files were created when a person claimed land under an act of Congress. They first had to fill out an application, and sometimes provide other information(marriage or immigration documents), at the local General Land Office.
Question:Will the USPTO advise me as to whether a certain patent promotion organization is reliable and trustworthy?
Answer:
No. The Office has no control over such organizations. The Office will publish complaints regarding invention promoters and replies from the invention promoters. The Office will not undertake any investigation of the invention promoters.
