The latest lawsuit comes from a Texas shell company named “Touchscreen Patents”. The suit names RIM, also Apple, as the defendants for infringing on a patent for drag, tap, and scroll. The company names the PlayBook as one of the devices that infringes on the patent.
These days no matter where you look, just about every day you see news of one of the top tech vendors getting sued for one reason or another. Some lawsuits are probably deserved, but some are ridiculous. Am sure as corporations try to put one up on the competition, they will keep running into all sorts of patent trolls that just sit on these patents waiting for a big name company to use similar technology and sue them.
