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.
