This posting follows up on an earlier posting about Pluscodes. In an earlier post, I mentioned that the article "Decoding A VCR Controller Code" in the July 1992 Cryptologia mentioned that "Gemstar claims copyright and patent protection on the PlusCode numbers and software to create them." Trademarkscan shows that Gemstar has registered the trademark VCRPLUS+ (and Design) with the U.S. trademark office. Inpadoc shows that Gemstar has pending applications in Japan, Europe, Canada, Brazil, and Australia. Those applications all claim priority from a U.S. patent application number 289,369 filed December 23, 1988. I did not see any issued patents. Thus, while the U.S. application is secret, anybody who wants to can see the published applications in Japan, Europe, Canada, Brazil, and Australia.
