In an interesting ruling just handed down last week from the USPTO, Apple has been denied the usage of the term "Multi-Touch" as a trademark, at least in the United States (they're still arguing for it in other countries).

In short, the reason for the denial is that the term has become to generic and is merely descriptive of a feature but does not meet the criteria of "acquired distinctiveness", which is determined by such things as sales success, length and exclusivity of use, and advertising expenditures. Evidently, the ruling board did not think Apple met the requirements, which is an interesting if not surprising decision. For everyone else in the smartphone business, they can now breathe a little lighter knowing "Multi-Touch" as a term is not Apple owned.

Note: For clarification, Apple still has a patent on Multitouch, but not the trademark.
