Trademark Resource
Gregory Richardson, over at the Trademarks and Intellectual Property Weblog, has a number of good posts about trademark fundamentals. If you’re in need of trademark help or some TM explanations such as the differences between trade dress and a trademark, check it out.
He’s been blogging since the beginning of the year, and I think he provides some nice, easy-to-understand information without a lot of the legal analysis you might not be interested in.
