Apple has patents on every feature for their phones. Most of these patents are very general in the description of what they do. So general in fact, that it's impossible for competing platforms like Android, Windows Phone 7, and Blackberry to have any similar features without technically infringing. Apple is suing these companies in a clearly unfair and anti-competitive way. To quote a recent article, here are just a few examples. As you read these, think about all the other companies whose services do the things listed. If all of these were enforced to the letter, it would put other companies out of business, or force them to design a radiaclly different way for people to interact with their phones.
US Patent No. 5,946,647 - this patent was filed in 1996 (issued 1999) and covers detecting data, such as a phone number, in an email or web page, creating a link to that data, and initiating an action like calling the phone number when the user selects the link. The data could also include addresses, dates, etc
US Patent No. 8,086,604 - this patent claims priority back to 2000 (issued Dec. 2011) and covers searching multiple sources of information (on device and elsewhere) through a single search interface, such as Siri. Apple specifically touts Siri in its injunction request, but also argues that a unified text search is covered by the patent as well.
US Patent No. 8,046,721 - this patent claims priority back to 2005 (issued Oct. 2011) and covers Apple's signature slide-to-unlock feature. While Apple already has patent coverage on an image unlock feature, this newest patent is obviously intended to be a bit broader — likely addressing potential workarounds implemented by Google and OEMs over the last couple of years.
US Patent No. 8,074,172 - this patent was filed in 2007 (issued Dec. 2011) and covers providing word suggestions while the user types on a touchscreen keyboard, where the suggestions can be accepted or rejected by the user.
Tell Apple to stop this frivolous and anti-competitive behavior!
