Patent Examples

For each patent, the United States Patent and Trademark Office issues a single original version, which comes neatly bound in a cover with a nice ribbon.  The original patent document, often called the "ribbon copy", is quite impressive when shown to a jury determining whether the patent is infringed.

While the cover is impressive, the inside sheets stating the substance of the patent are what really matters.  Copies of the patent usually show only the text and drawings, not the cover.
