[time-nuts] WWVB / Xtendwave patents

[Joe Gwinn]

The US changed over to the rest-of-world patent system, where patent 
applications are public for a period before grant, precisely to get 
input from the entire technical community.

The granted patent (8270465) would be hard to overturn at this point.

As for the patent application (2012/0082008), one can file comments 
against a patent application pointing out prior art and suggesting 
that something being claimed is in fact obvious to those skilled in 
the art.  For prior art, one points out existing patents and 
published articles.  Simple assertions are not sufficient.  The 
Patent Office will then consider all prior art received when deciding 
to grant or to deny a patent.
