Although there has been a raging price war on ereaders recently, Amazon may have a leg up on the competition with a new patent it was awarded yesterday.
Filed back in 2006, this patent describes a dual-screened ereader, coming with one larger area to read from, while supporting a smaller LCD display. Obviously, this was the original Kindle design.
Since the Barnes & Noble Nook comes with just that — a large e-ink screen and a smaller LCD display — the company could be sued for patent infringement. You may be wondering why no one knew of this patent until now. Seems that since Amazon didn't file any foreign patents on the product during the approval process, they didn't have to publish the application. Will Amazon sue for infringement? Only time will tell.
