Just thought I would appear to say there is a rather large difference between copyright (the right afforded to every published work that means only the copyright holder can distribute it for so many years (although in practice this limit keeps being extended)) and trademark (in this case an application made to a place, usually upheld by a government or regional body of some form, for a name/likeness of a brand/service/product that has to be maintained but can last indefinitely, there is also the lesser form that just allows you to say trademark that acts along similar lines to copyright- anybody/automatic but lesser abilities).
Personally I would consider it a dick move on the part of Valve but although my knowledge of US trademark law is at best that of a layman (it varies a slight bit from European trademark law and that is enough to trap you if you are not careful) it would appear to be a case of "should have moved faster" on the parts of others on the letter of the law front.
