Microsoft has confirmed that it is attempting to block Apple’s trademark application for the phrase “App Store.” BBC News reports that Microsoft has asked the US Patent and Trademark Office to reject the application on the basis that it is too broad. “An ‘app store’ is an ‘app store’,” said Russell Pangborn, Microsoft’s associate general counsel. “Like ‘shoe store’ or ‘toy store’, it is a generic term that is commonly used by companies, governments and individuals that offer apps. The term ‘app store’ should continue to be available for use by all without fear of reprisal by Apple.” Apple first filed for the trademark in 2008, and this week launched its second application store—the Mac App Store—alongside the release of Mac OS X 10.6.6.
