Google might be the king of web-based search, but the field is still wide open when it comes to mobile search. Many a few companies are taking different approach to mobile search, and Nokia is one of them.

We would let the Search Engine technology experts handle the analysis of this patent application. However, it does make sense for Nokia to do research around this topic, especially since it is betting so heavily on camera phones.
