Apple, Inc. was hit with a patent infringement lawsuit Thursday (read it below) alleging that the company’s iPad 3 tablets and Macbook Pro computers violate four light emitting diode (LED) patents. The case was filed in in federal court in Delaware by claimed patent holder LED Tech Development LLC, a Delaware limited liability company based in Tyler, Texas, the city that is a patent litigator’s combat zone.
Each of the four infringement claims, the complaint charges, involve Apple “products utilizing pulse-width modulation signals to drive light-emitting diodes.” Apple’s newest iPad a/k/a the ‘iPad 3,’ and Macbook Pro are named specifically.
