File Date

The lawsuit, filed July 20, 2012, in the United States District Court for the District of Delaware, was filed on behalf of Flatworld Interactives, LLC, a company specializing in commercialization of touchscreen technology. The company was founded by Dr. Slavko Milekic, a professor of Cognitive Science & Digital Design at the University of the Arts in Philadelphia, Penn. 

According to the complaint, Professor Milekic developed gesture recognition touch screens for use by children as an easier and more intuitive means of interacting with a computer. 

The lawsuit alleges that LG’s smartphones and tablets, including the Optimus, Elite, Viper, Lucid, Nitro, Spectrum, Marquee, Ignite, myTouch, DoublePlay, Esteem, Enlighten, Thrill, Revolution, Genesis, G2X, Thrive, Phoenix, Axis, Apex, Vortex, Ally and T-Mobile G-Slate infringe U.S. Patent No. RE 43,318, entitled User Interface for Removing an Object From a Display, which is registered to Flatworld.

The patent allegedly covers the use of certain finger gestures commonly used on LG devices, including a “flick” of the finger used to remove images from the display.

The lawsuit sought a ruling from the court affirming that LG has infringed the patent, an injunction enjoining LG from continued infringement, and an award of damages to compensate Flatworld.

The case settled on confidential terms.
