Comments on United States Patent Assignment InformationThe text below is a copy of an email that I sent the Patent Interference User's Group (PIUG) on November 4, 2003, regarding United States Patent Assignment Information. On that form, they write in the name they want to appear on the patent as the Assignee. The name shown as the assignee on an issued U.S. patent is not conclusive evidence that an assignment exists, and it is not conclusive evidence that the entity listed as the assignee is, even at the time of issuance of the patent, the owner of the patent. It is just a name. The assignment database generated by the USPTO shows the information the person filing a copy of the executed assignment writes on the "RECORDATION FORM COVER SHEET." The USPTO's assignment database does not include the actual assignment document. The USPTO stores image copies of the actual assignment documents on micro fiche available at the USPTO, indexed by reel/frame. You can identify allegedly assigned patents by searching the assignment database, and then pull up the ACTUAL assignment documents by the reel/frame associated with each patent number.

That assignment document would not result in a valid assignment, and B would not have valid title to the patent.
