As you know from our co-posted entry, siRF and u-Nav are in the midst of a patent infringement tussle. In fact, SiRF started this brawl with their lawsuit in August 2005, to which u-nav counterclaimed, etc, etc., etc.
Since the ideaCop(tm) tries to be impartial at all costs, or at least within our budget at the time, we thought that it might be useful to deliver to our readers a file of potentially material prior art references to one of the siRF patents in play, namely, United States Patent 6,297,771
These references are in the attached file and we trust that you folks will relish them as much as we did in preparing them.
Post your comments and alternative references.
