Positive Technologies is absolutely positive that Apple and 12 other companies nicked three of its best ideas.

Filed in the Eastern District of Texas, Marshall Division, the lawsuit claims that the 13 companies infringe on its patents ’457, ’558 and ’588. The ’457 patent covers “DC Integrating Display Driver Employing,” the ’558 patent is “DC Integrating Display Driver Employing Pixel Status Memories” and the ’588 patent describes “DC Integrating Display Driver Employing Pixel Status Memories.”

Apple has fallen foul of the patent because of its computers. According to documents filed with the courts, Apple infringes the patent “by manufacturing, using, selling, offering to sell, and/or marketing several types of consumer electronics, including but not limited to laptop computers, desktop computers and all-in-one computers incorporating an LCD display panel using display acceleration techniques claimed in the ’457 Patent.”

But it is not the only big name on the write. There is also Sony, HP, Acer, Gateway, Dell, Asus, Lenovo, MSI, Amazon, Barnes & Noble, ViewSonic and Kobo. The only reason for focusing on Apple is that it claims to have invented everything.

The fact the case is being heard in the Patent friendly courts of Texas is not a good sign for Positive Technologies. That is normally the sign of a patent troll in action.
