When we get nonsense like this it's no surprise that folk file for nonsense trademarks. Most large(ish) companies will hit a suit like this sooner or later, and having a mark filed and rejected is a reasonable defense. If a company with a perceived "moral right" to a name can't get it it's absurd that a company with lesser rights can.

Most companies simply hang onto their trademark and don't do anything with it. When opportunistic suits come into play like this it shows the absurdity of current IP laws.

Then again IP law allows us to patent business processes, or as Microsoft has a habit of doing, software processes which are already integrated into competing products (proving that prior art assertions are broken on application.)

Rhubarb rhubarb rhubarb; that's the most sensible thing I can say about this kind of absurd litigation.
