It only took four years, but Apple has finally been denied the "multitouch" trademark.
The Trademark Trial and Appeal Board at the United States Patent and Trademark Office upheld a USTPO lawyer’s decision to deny Apple’s initial 2007 trademark application. Apple’s failed appeal means the term “Multitouch,” not the technology itself, is free for anyone to use.
The trademark attorney pointed out that the term “multitouch” has taken on a generic meaning and an extremely large number of manufacturers and publications use the term to describe the touch based interfaces found in nearly every phone and tablet currently on the market. The ruling in its entirety can be found here on Scribd.
“Thus, from the foregoing, we find that “multi-touch” not only identifies the technology, but also describes how a user of the goods operates the device. Based on the evidence discussed above, as well as other evidence in the record, we agree with the examining attorney that MULTI-TOUCH indeed is highly descriptive of a feature of the identified goods. We now consider whether applicant has submitted sufficient evidence to establish acquired distinctiveness of this highly descriptive term.” — USPTO
