Comment they slipped in a very important claim... (Score 1) 323
just totally personally annoying and just my read on it, but, the patent was clearly edited to get around the "radio beaconing location" aspects from this paper:
Composable Ad hoc Mobile Services for Universal Interaction
T. D. Hodes, R. H. Katz, E. Servan-Schreiber, L. A. Rowe
Proceedings of The 3rd ACM/IEEE International Conference on Mobile Computing (MobiCom '97)
Budapest, Hungary, September 1997, pp. 1-12.
(disclosure: I'm the author)
but then the addendum slips the claim back in 11 years later:
".Iadd.29. The method of claim 24, where the beacon is a radio frequency beacon..Iaddend."
You can tell this this is the case because the examiner forced a citation of an article in the exact same proceedings as (theoretically) non-competing prior art ("Location-Aware Mobile Applications based on Directory Services," MOBICOM 97, 1997, Budapest, Hungary, pp. 23-33.), yet conspicuously allowed the above to be left out, almost certainly after a bunch of claims editing.
This is also why there is so much work done in the abstract & write up to trip over itself to focus on "GPS" and "coordinates" as the location technology -- any post-1997 beacon-based location was (and still should be) unpatentable.
