There have been countless lawsuits filed in the mobile handset world, with just about every major player suing every other over technology and feature patents for their devices. With Motorola suing Apple earlier in the month over a ton of different mobile related patents, its no surprise that we are now learning Apple is suing the company over 6 multitouch related patents in two patent infringement lawsuits.

The lawsuits name a number of Motorola handsets and smartphones including DROID, DROID 2, DROID X, Charm 1, Devour, Devour i5, Backflip, CLIQ, and CLIQ XT. Earlier in the month, Motorola lawsuits against Apple covered just about everything other than multitouch, including antenna design, the App Store, MobileMe, and location based services.
The 6 patents in question are listed below, courtesy of our friends at Patently Apple:
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.
