JamesAlfaro wrote to mention an Ars Technica story, which goes into the recent filing of a suit against Google Talk. A Delaware corporation claims that Talk infringes on two of its patents. From the article: "You've probably never heard of Rates Technology Inc. (RTI), and that wouldn't be surprising since the company has no products and offers no services. By all appearances, RTI is a company that was set up to collect licensing fees and pursue settlements related to the company's patent portfolio. Gerald J. Weinberger, president of Rates technology Inc., once said that the company was 'an enterprise based on patent licensing,' and that much of its business depended on the courts." Certainly seems like there are a lot of those businesses around nowadays, huh?
