While we’re talking patent trolling, let’s talk about the global Apple-Samsung battle. Apple has been suing Samsung in courts around the world, claiming that the design of the Galaxy Tab 10.1 rips Apple’s patented design of the iPad, which consists of, um, a rectangle with a screen on one face. How they got a patent for that is beyond us, but that template has prompted judges in Australia and other countries to block sales of the Galaxy Tab until the case is decided. Samsung’s getting pretty fed up with it all, and it today, it threatened to withdraw from Australia altogether if the injunction wasn’t lifted soon.
