Lantiq vs. 雷凌

Lantiq於2010.3.在德國杜塞爾多夫地方法院向盛達電提出侵權訴訟，同時指其供應商誠致科技(TrendChip Technologies)所提供的晶片組導致盛達電的產品產生專利侵權行為。
2010.10.誠致科技與雷凌合併之後，在全球寬頻網路晶片市場排名第三，2010.11.馬上就以雷凌科技的名義在美國威斯康辛州西部聯邦地院對Lantiq提出US5,394,116專利侵害的控訴，至此雙方官司訴訟陷入互控的僵局。
2011.1.14.Lantiq以US6,351,799及US7,061,904等2項專利侵權為由，向加州北部聯邦地院提出控訴。

Lantiq
Lantiq前身為Infineon旗下的有線通訊事業處，2009年Infineon將其售予私募基金投資公司Golden Gate Capital後才有了Lantiq的出現，目前為僅次於Broadcom的全球第二大寬頻網路晶片供應商。本案的系爭專利原屬Infineon所有，因併購而成為Lantiq的專利，其主要技術在於晶片的控制器整合技術。

Title : Integrated circuit for executing software programs
Filing Date : 1998.7.14.
Issue Date : 2002.2.26.
Abstract :
The integrated circuit executes software programs. The electronic components of the integrated circuit and/or the electrical connections between them can be selectively broken and/or created. The wiring of the electronic components and/or their function and/or their mode of operation are thereby at least partly individually configured. The connections are thereby configured dynamically and in parallel during the operation of the integrated circuit.

Title : Integrated access device controller
Filing Date : 2001.4.9.
Issue Date : 2006.6.13.
Abstract :
A network processor (12) for a voice over Internet protocol phone integrates a universal serial bus port (56), a pair of IEEE 802.3 MACs (70a), a repeater (70b), and a pair of pulse code modulation (PCM) ports (24) such that the network processor can be combined with other peripherals to transmit both voice and data over an Internet protocol network (13).

Title : Fractional phase shift ring oscillator arrangement
Filing Date : 1993.12.29.
Issue Date : 1995.2.28.
Abstract :
A ring oscillator has a plurality of oscillator outputs, each of which carries an oscillating signal of a given frequency and thus repetition period but with a phase shift of a predetermined fraction of the repetition period from any one of the oscillator outputs to a next oscillator output in a predetermined repetitive sequence. The inputs of a selector are each connected to a respective one of the oscillator outputs. The selector includes a number of individually actuatable selector switches that are so actuated as to establish a connection between the selector output and only any selected one of the selector inputs at any time. The actuation is accomplished in a first mode, in which the selector switches maintain the connection, or in a second mode in which the selector switches intermittently index the connection in the predetermined repetitive sequence among the selector inputs.
