DigiTude出手囉

昨天提到有關Apple與DigiTude間的八卦,今天來看看DigiTude出手後,有那些公司遭殃。
DigiTude Innovations, LLC於2011.12.2.在ITC及Delaware地方法院分別提出侵害專利的告訴,系爭專利分別為:US5926636、US5929655、US6208879、US6456841,主要涉及4G技術使用於可攜式通訊裝置,被告群有:
Samsung Electronics Co., Ltd.,
Samsung Electronics America, Inc.,
Samsung Telecommunications America, LLC
Sony Corporation, Sony Corporation of America, Sony Electronics, Inc., Sony Ericsson Mobile Communications AB, Sony Ericsson Mobile Communications (USA), Inc.
Research In Motion LTD., Research In Motion Corp.
Nokia Corporation, Nokia, Inc.
Motorola Mobility Holdings, Inc.
LG Electronics, Inc., LG Electronics USA, Inc., LG Electronics Mobilecomm USA, Inc.
Amazon.com Inc.
HTC Corporation, HTC America, Inc.
這麼多的手機廠商,您也許會發現:怎麼沒有Apple?原來其中的US6208879號專利,曾經授權給Apple,但原因只是這麼單純嗎?這二家公司的關係是不是這麼的單純?值得我們後續觀察!

Title : Remote procedural call component management method for a heterogeneous computer network
Filing Date : 1996.2.21.
Issue Date : 1999.7.20.
Assignee : Adaptec, Inc.
Abstract :
In response to a component management function call by a remote client application, the component management application programming interface (API) generates a message that identifies the called function and the version of the component management API. The component management API calls a local message transfer RPC command to send the message to a RPC command module. The RPC command module processes the local message transfer RPC command, and packages the message for transfer as a RPC over the heterogenous network. The RPC command module sends the packaged RPC to a network stack which in turn transmits the packaged RPC over the heterogenous network to a network stack in the server computer. The server network stack provides the packaged RPC to a server RPC command module that unpacks the RPC in a conventional manner to obtain the original message. The message is passed to a server component management API. The server component management API parses the message to determine the computer architecture of the client computer. With this information, server component management API reads the version specified in the message. If the specified version is incompatible with the version of the server component management API, a reply indicating the version incompatibility is transmitted to remote client application and otherwise the message is processed further by the server component management API.

Title : Dual-purpose I/O circuit in a combined LINK/PHY integrated circuit
Filing Date : 1997.3.25.
Issue Date : 1999.7.27.
Assignee : Adaptec, Inc.
Abstract :
A dual-purpose I/O circuit for use in an integrated circuit having a primary circuit is provided. The dual-purpose I/O circuit includes two conducting pads, two single-ended I/O cells and one differential I/O cell. Several dual-purpose I/O circuits can be used within a single integrated circuit to support both single-ended and/or differential mode I/O signaling between external circuits and devices and a primary circuit within the integrated circuit. Within each dual-purpose I/O circuit, a first single-ended I/O cells is connected to a first conducting pad, a second single-ended I/O cell is connected to the second conducting pad and a differential I/O cell is connected to the both the first single-ended and second single-ended I/O cells and to both the first and second conducting pads. A control logic is connected to at least one of the first single-ended, second single-ended and differential I/O cells. The control logic is arranged to selectively enable and disable at least one of the first single-ended, second single-ended and differential I/O cells. The primary circuit can include any digital and/or analog circuit. The primary circuit can include a combined LINK/PHY circuit configured to support IEEE-1394 standard buses and communications.

Title : Mobile information terminal equipment and portable electronic apparatus
Filing Date : 1999.3.8.
Issue Date : 2001.3.27.
Assignee : Mitsubishi Denki Kabushiki Kaisha
Abstract :
The objective of the present invention is to have a desired screen displayed with shortened waiting time in using functions for the electronic note, etc., while engaging in telephone talk. Another prime objective of the present invention is to achieve an easy-to-use mobile information terminal equipment which also functions as an electronic note, word processor, personal computer, and so on. In transitting from telephone mode (cover closed status) to information terminal mode (cover opened status), the screen to be displayed is determined to be either a historical information, talk log information, or user setting screen. This enables the user to obtain the desired screen with fewer number of operations and with less waiting time.

US6456841
Title : Mobile communication apparatus notifying user of reproduction waiting information effectively
Filing Date : 1999.6.1.
Issue Date : 2002.9.24.
Assignee : Mitsubishi Denki Kabushiki Kaisha
Abstract :
A mobile communication apparatus capable of notifying a user of the presence of reproduction waiting information like a short message with proving the user with an impact. A controller of the mobile communication apparatus decides, when a flip is opened, whether the reproduction waiting information is stored in a RAM. If it is stored, the controller displays on a screen a window image including an icon associated with the reproduction waiting information. If there are more than one pieces of the reproduction waiting information, multiple icons are displayed in the window image. One of the icons is selected by placing the cursor on it, so that the reproduction waiting information associated with the icon is replayed in response to the operation of a memory key by the user.
