From what I can tell (the translation isn't perfect), one of the patents BlackBerry sued them over is being able to "email entire chat history". Also, "switching from one chat to another" and "friend proposals".<p>Lmao. This stuff is ridiculous. I'm so glad my country (India) doesn't have software patents.<p>Edit: so I looked it up, and the software patent situation is kinda weird here:<p>> Software Patents in India is granted for an embedded software in a mobile application, and/or software plus hardware combination. However, patent law in India does not allow patent protection for software per se, whereby patenting a computer program is prohibited.
