What is Graviton?

March 19, 2011

The recent appearance of a Graviton test note on eBay piqued this author’s curiosity. The results of my research are as follows:

Graviton appears to be an older attempt by De La Rue at an opaque polymer substrate with a transparent area or window. Polymernotes.de cites Graviton test notes as circa 2002. A check of the UK Intellectual Property Office yielded no apparent registered trade mark by DLR for the name Graviton. A search of the DLR web site yielded no results.
