Adwords Trademark Suits Again!

Thread Title:
More AdWords Trademark Suits
Thread Description:

John Battelle is reporting more G Adwords suits:

This one has Company A (Brannock, the maker of those foot measuring devices) suing a Company B (ABC Industries) because Company B has purchased Company A's trademarks as AdWords. This is distinct from Company A suing Google and/or Yahoo, as is the case with Gieco, American Blind, et al.

Seems like quite the trend doesn't it?
