FAQs Patent Questions
Question:Once the patent is granted, it is outside the jurisdiction of the USPTO
Answer: Once the patent is granted, it is outside the jurisdiction of the USPTO except in a few respects. The Office may issue without charge a certificate correcting a clerical error it has made in the patent when the printed patent does not correspond to the record in the Office. These are mostly corrections of typographical errors made in printing.
Question:The requirements for filing a substitute specification is stated under the 37 CFR 1.125
Answer:
When applicants file a substitute specification, the following are required under 37 CFR 1.125: (1) a statement that the substitute specification includes no new matter; (2) a marked-up version of the specification with markings to show all the changes relative to the immediate prior version; and (3) a clean version of the substitute specification.
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.
