Intel, AMD, Nvidia, Microsoft, Apple, Google others sued over patent

We’ve come across Xpoint Technologies before. And now we’ve come across Xpoint Technologies again.

Last time round, as we reported on the IT Examiner, a heap of firms got a writ from Xpoint.

The company launched a patent action in a Delaware court suing Microsoft, Intel, Marvell, Hewlett Packard, Cypress,  Quicklogic, Freescale, Texas Instruments, Google, T Mobile, HTC, Apple, Sony, Ericsson, Sony Ericsson, Philips, LG Electronics, Research in Motion, Motorola, Nokia, Palm, Nvidia, AMD, Dell, AT&T, Verizon, Cellco and Sprint.

Heck, if you’re going to go on a patent litigation spree, you may as well go the whole hog.

This time round, Xpoint filed a 50 page complaint related to patent number 5,913,028 – Client/Server Data Traffic Delivery System and Method. This, says the filing is a direct data delivery system and method for program controlled direct transfer of data along a bus or data pathway between peer IO devices in an apparatus or a network, bypassing the CPU.

Mr Wang, who used to work for Ungermann-Bass, says that the 028 patent increases functionality for cellphones, media players, PCs, GPS, and other devices. Cellphones sold by some of the defendants use the patent to transfer data from the camera sensor to the LCD screen, it’s alleged. Chipsets for computers also infringe this patent, it’s alleged.

The patent owner alleges he has talked to several of the defendants discussing the substance of the patents.
