We knew this day would come eventually when we learned more about why Kik was pulled from App World. RIM has filed a patent lawsuit against Kik, and while we don’t know the exact patents RIM is claiming Kik has infringed on, a good guess is that it has to do with a RIM patent on BBM’s sent, delivered, read, and typing indicators. Considering the CEO of Kik, Ted Livingston, used to work at RIM, it wouldn’t be a stretch to think he had insider knowledge about the patent details.
Here is a thought: maybe RIM wouldn’t have sued Kik if they didn’t use this patent on other devices. The fact that the company essentially brought BBM to other platforms in such a way is bad for RIM’s business. Carriers will often say that BBM is the number 1 customer retention tool for BlackBerry, and if this opens up to other platforms they lose a bit of competitive advantage.
