WiAV Solutions has recently unloaded both barrels of legal action on RIM, Apple and Palm regarding what’s called Adaptive Multi-Rate compression, a GSM voice compression technology. AMR is used to detect silence rather than sound, altering music to accommodate voice, and power management. Up to ten patents are supposedly being infringed upon, but AMR was included in the GSM standard back in ’98, so you have to wonder how it will all end up. WiAV only actually owns two of the offending patents, while they’re dragging their liscensor, Mindspeed, into the case to defend the rest of the technologies. On the whole, it sounds like this is a shaky case already, and probably won’t get too far. If you’re fluent in legalese, you can take a look at some of the court papers here.
