Nokia filed a trademark application for the name "Nokia Zoom". That's what they had to do protect that name, given it has the word "Nokia" in it, I don't know who would want to use that term if they aren't Nokia.
The application is currently being processed by the trademark authorities.
This obviously has everything to do with the July 11th announcement in NYC, where Nokia will unveil its next generation Lumia series.
These Lumia 1000 series phones will undoubtedly have some new zoom technology, just like the Nokia 808 Pureview did.
