The legal battle over the BBX name

If you were to choose a name of an important, new mobile operating system upon which you were pinning the future hopes of your beleaguered company, you would probably make sure you chose one that wouldn't become the target of a lawsuit that could require you to change the name.

Trademark infringement generally requires that there be no "confusion" between marks, and Basis contends that since both refer to operating systems, this is a clear-cut case. In fact, Basis says that it has already fielded questions from customers about the confusion. For its part, RIM obviously disagrees — it responded to Basis' original allegations last week in a statement given to Reuters:
