Patents are listed in reverse chronological order by the year in which they were issued or, if not yet issued, by the year in which they were published. The most recent application is at the top. Patent titles may be truncated for space.

Each patent title links to a synopsis of the patent. In turn, the US patent number in each synopsis links to the official patent document maintained in the full-text and image database of the United States Patent and Trademark Office (USPTO).

 

Patents

Patents have been generated from new technologies or developments that grew out of systems on which Robert worked. He currently has/is an inventor of eighteen patents issued or published in the United States and is the principal inventor of twelve of these. As of April 2008, only the topmost patent in the list below has not yet issued. Two of the patents in this list are reissues of prior patents. Patents with the same name as others are different patents because they have different claims. Scores of international patents reference Robert's US patents.
