When I say "smartphone patent," you probably think "Apple trying to patent thin, rectangular shapes with flat surfaces." But not every smartphone patent is lame and/or boring--the files held by the U.S. Patent and Trademark Office also have their wild side.
Amid the patents for boring innovations, such as slide-to-unlock and pinch-to-zoom, you can find patents and patent applications for crash-protected smartphones, phone alerts that ring your skin, and smartphones that look like they can fly.
