| Subseries I: United States Patents, 1911-1939 |
|
This subseries consists of patents issued by the United States government. There are two types of US patents, a design patent and a utility patent. A design patent refers to the visual ornamental characteristics embodied in, or applied to, an article of manufacture. A utility patent protects useful processes, machines, articles of manufacture, and compositions of matter. 1 Materials in the series consist of the actual certificates issued, official reprints by the Government Printing Office, and related materials. Patent certificates issued before May 1922 hold the original signature of the Commissioner of Patents. After this time, all patent certificates were rubber-stamped. Materials are organized by patent number; the first five patents are design patents and the rest of the patents are utility patents. 1 United States Patent and Trademark Office, "Patents Guidance, Tools & Manuals," http://www.uspto.gov/patents/resources/types/index.jsp, accessed August 8, 2010. | ||
