FAQs Patent Questions
Question:Where Can I get a Copy of a Patent?
Answer: Copies of patents can downloaded (for free) from the following websites: The USPTO The European Patent Office These sites only allow one to download patents one page at a time (although you can get the text, without images, from the USPTO all at once) and can be time consuming to obtain. In some instances, it may be easier to order a patent from the USPTO, or from one of many commerical sources such as Dialog and Micropatent.
Question:What are Credit Patents?
Answer:
Credit patents are similar to Cash; lands could be purchased under the Land Law of 1800 from the General Land Office. This credit system allowed purchasers to pay in installments over a four-year period. A delinquent payment or non-payment of the full balance resulted in forfeiture to the U.S. Because of the economic hardship Congress quickly abandoned the credit system and through the Act of April 24, 1820 required full payment for land to be made at the time of purchase.
Question:How can I view the patent images?
Answer:
The PTO Web Patent Full-Text Database includes the full text of all patents granted since 1976, and the patent number, issue date, and current US classification for all patents granted from 1790 through 1975. At the top of each text display page is a button marked "Images". Clicking on that button will display the full-page image of the first printed page of that particular patent, along with navigational tools allowing the viewing of all the other pages.
