Several IP news items today. First it is being widely reported that the Supreme Court is cracking down on patent trolls - requiring the Circuit Court not to issue an injunction without considering what the potential damages might be. This may make it harder for a company without a patent to threaten to close down a business by getting an injunction - we will see. However, they may claim huge damages on account of not being able to enter the market, so it probably won't make much difference.
In the other direction Slashdot is also reporting that Creative is suing Apple over the iPod interface. Couldn't happen to nicer guys: Apple having done their best to patent the interface as well. It is probably a good reason to sell stock in both firms.
