Claiming infringement their US Patent No. 5,913,028, entitled “Client/Server Data Traffic Delivery System and Method, Xpoint Technologies, Inc. has filed suit against Microsoft Corporation, Intel Corporation, Marvell Technology Group, Ltd., Marvell Semiconductor, Inc., Hewlett-Packard Company, Cypress Semiconductor Corp., QuickLogic Corporation, Qualcomm, Inc., Freescale Semiconductor Holdings I, Ltd., Freescale Semiconductor, Inc. (“Freescale Semiconductor”), Texas Instruments, Inc., Google Inc., T-Mobile USA, Inc., HTC Corporation, HTC America, Inc., Apple Inc., Sony Corporation, Telefonaktiebolaget LM Ericsson, Sony Ericsson Mobile Communications AB, Sony Ericsson Mobile Communications (USA), Inc., Philips Electronics, N.V., Philips Electronics North America Corporation, LG Electronics, Inc., LG Electronics USA, Inc., Research in Motion, Ltd., Research in Motion Corporation, Motorola, Inc., Nokia Corporation, Nokia Inc., Palm, Inc., Nvidia Corporation , Advanced Micro Devices, Inc., Dell Corporation, AT&T Inc., AT&T Mobility LLC, Verizon Communications, Inc., Cellco Partnership (“Cellco”), and Sprint Nextel Corporation.
Xpoint claims, "the ‘028 Patent invention provides significantly enhanced functionality for a variety of types of electronic devices, including without limitation cell phones, personal media players, personal computers, global positioning system (“GPS”) devices, and the like (generically, “data-processing devices”). One example of such enhanced functionality is “sideloading.” Certain cell-phone and personal media players manufactured and sold by certain Defendants use the ‘028 Patent technology to facilitate sideloading, which permits the transfer of information directly from one local device, typically a universal serial bus (“USB”) network I/O device connected to a personal computer, across a bus to the I/O of another local device such as a storage I/O device of a cell phone or personal media player, bypassing the CPU and central memory. In another example of increased functionality, the ‘028 Patent technology is infringed by processors and chipsets for computers, cell phones, and smart phones manufactured and sold by certain Defendants that use “northbridge-southbridge” architecture to transfer data directly between I/O devices across a bus that bypasses the CPU and central memory. The ‘028 Patent technology is also infringed by cell phones sold by certain Defendants that contain digital cameras and use the ‘028 Patent technology to transfer data directly from the camera sensor (input I/O) to the LCD screen (output I/O), bypassing the device’s CPU and central memory and permitting these cell phone digital cameras to function in viewfinder mode and to display images instantaneously and continuously on the screen. Yet another example of enhanced functionality made possible by the technology protected in the '028 Patent is cellular video sharing. In cellular video sharing, the output of the camera sensor of a data processing device is transferred directly to a network I/O unit of the device, bypassing the CPU and central memory of the device. Certain devices manufactured and sold by certain Defendants are capable of cellular video sharing and infringe the '028 Patent.
