When you have a technology as successful as multi-touch, you’re probably going to want to do everything in your power to protect infringement of your patents by rival manufacturers – and that’s exactly what Apple is doing today.

The Cupertino-based firm is going after mobile phone manufacturer Motorola after it claims the company has infringed on six of it’s filed patents regarding it’s mutli-touch screen technology. Those six patents cover a number of devices; Droid, Droid 2, Droid X, Cliq, Cliq XT, BackFlip, Devour A555, Devour i1, and Charm 1, and include:

One: Apple, Inc patent titled: Ellipse Fitting for Multi-Touch Surfaces: Patent Abstract: Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing, multi-touch surface. Identification and classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.

Two: Apple, Inc patent titled: Multipoint Touchscreen: Patent Abstract: A touch panel having a transparent capacitive sensing medium configured to detect multiple touches or near touches that occur at the same time and at distinct locations in the plane of the touch panel and to produce distinct signals representative of the location of the touches on the plane of the touch panel for each of the multiple touches is disclosed.

Three: Taligent, Inc patent titled: Object-Oriented System Locator System: Patent Abstract: A method and system for adding system components (documents, tools, fonts, libraries, etc.) to a computer system without running an installation program. A location framework is employed to locate system components whose properties match those specified in search criteria. The framework receives notification from the system when system components whose properties match the search criteria are added to or removed from the system.

Four: Apple, Inc, patent titled: Touch Screen Device, Method, and Graphical User Interface for Determining Commands by Applying Heuristics: Apple’s invention generally relates to electronic devices with touch screen displays, and more particularly, to electronic devices that apply heuristics to detected user gestures on a touch screen display to determine commands.

Five: Apple Computer, Inc. patent titled: Method and Apparatus for Displaying and Accessing Control and Status Information in a Computer System: Apple’s invention generally relates to the field of computer systems; particularly, the present invention relates to displaying a status and control function bar or window to enable access of user selected indicia to a computer system user.

Six: Apple Computer, Inc. patent titled: Support for Custom User-Interaction Elements in a Graphical, Event-Driven Computer System: Apple’s invention relates to graphical, event-driven computer systems, more particularly to custom interactive user-interaction elements in a computer system having a window-based graphical user interface.

You may remember earlier this month that Motorola tried to sue Apple, maybe Apple is giving them a taste of their medicine? – Either way, this will certainly be interesting to watch as it plays out.
