A trademark 'trainwreck' may be brewing over Grand Central, which may soon come to represent different things to the same audience. MacNN reports that the US Patent & Trademark Office published Apple’s latest trademark application for Grand Central under application 77626943. As nifty as the future support for multicore systems within Snow Leopard appears to be, Macworld insightfully reminds us that Google "...offers a service of the same name." While the name may be the same, Google claims that Grand Central users "...can be reached with a single number, answer a call at any phone you want, seamlessly switch phones in the middle of a call, and even know whether a call is important before you take it." Given Apple's well deserved reputation of slavish attention to detail for their products, it's a bit of a mystery why the company is so challenged by the concept of trademark due diligence. The present case is highly reminiscent of the not too long ago brouhaha over the Rendevous name, which Apple was forced to abandon in favor of Bonjour.
