This whole patent troll business has gotten way out of hand. The notorious Wi-Lan patent troll has sued BlackBerry yet again, the third such lawsuit against BlackBerry, this time targeting LTE BlackBerry devices. They are asking for an injunction in the US against all LTE based BlackBerry devices for U.S. Patent No. 8,274,991 which covers a “protocol for allocating upstream slots over a link in a point-to-multipoint communication system.”
In other words it seems like multi-point uplink connections over LTE are attempted to be covered by this patent. I cannot imagine it is just BlackBerry following this standard but it should be interesting to see how it plays out yet again.
