A trademark is more precarious than a patent. If you don't defend the trademark in a timely manner, the infringer can make a laches defense. Unchecked infringement - however minor - can also cumulatively damage the distinctiveness of the trademark, making it more difficult to defend against future infringement.

The "Trademarks must be defended" and the "yell fire" concepts are the 2 most over stated and misunderstood legal topics on the planet.

>>Quite simply, the view that a trademark holder must trawl the internet and respond to every unauthorized use (or even every infringing use) is a myth. It’s great for lawyers, but irritating and expensive for everyone else. And when done clumsily or maliciously, it chills free expression.
