- A patent is a **public record** describing an invention, it must
- include a detailed description of the invention and a set of
- claims that describe the invention for which the inventor
- demands an exclusive right or privilege. All U.S. patents
- are published in the Official Gazette of the U.S. Patent and
- Trademark Office (at least a description of the invention is).
-
- There are exceptions, we recently had to deal with a patent
- issued in 1947 or 1948 dealing with nuclear weapons that had
- only recently been declassified, even though the patent rights
- had run out no later than 1965. But, if the patent isn't
- classified, it should be available in the public domain.
-
- In addition, there are a number of databases covering the
- patent literature. The most applicable to this case would be
- Derwent which is available through STN and Dialog.
