An anonymous reader writes "Let's say you've been using the same, rather unique name on the Internet since the mid 90s. You've offered advice and written articles under that name on countless sites and forums. You own the domain name. It's your identity on all of the Instant Messaging, Email and Social Networking sites. You even use it as your eBay ID to buy and sell products (including computer software). Suddenly, a company comes along and files an application for a trademark on that name for use with a new software product. How do you proceed? Do you file an objection with the USPTO? What prior use rights do you have in a situation like this?"
