Mariner IC Inc. v. Texas Instruments Incorporated 2:16-cv-00434-JRG-RSP

Mariner IC Inc. v. MediaTek Inc. et al 2:16-cv-00435-JRG-RSP

Mariner IC Inc. v. Toshiba Corporation et al 2:16-cv-00436-JRG-RSP

Mariner IC Inc. v. Funai Electric Co., Ltd. et al 2:16-cv-00442-JRG-RSP

The plaintiff Mariner is based in Marshall.

It has pursued legal action to stop alleged infringement of United States Patent Numbers 5,650,666 and 5,846,874.

Per court papers, the ‘666 patent, entitled “Method and Apparatus for Preventing Cracks in Semiconductor Die,” was issued by the U.S. Patent and Trademark Office on July 22, 1997 while the ‘874 patent, which shares the same title, was issued on Dec. 8, 1998.

“The patents-in-suit generally cover anchor structures that are placed in the corners and around the edges of a semiconductor die to prevent cracks in the die due to stress,” they explain.

“The anchor structures are positioned at a 45-degree angle to the sides of the die and are comprised of at least a substrate layer, a metal layer and an oxide layer. The placement of the anchor structures more uniformly distributes stresses along the anchor preventing cracks at the corners of the die.”

Mariner seeks unspecified monetary damages and a jury trial.

Attorney Samuel F. Baxter of the law firm McKool Smith, P.C. in Marshall serves as the complainant’s lead counsel.

Semcon IP Inc. v. Huawei Device USA Inc. et al 2:16-cv-00437-JRG-RSP

Semcon IP Inc. v. MediaTek Inc. et al 2:16-cv-00438-JRG-RSP

Semcon IP Inc. v. STMicroelectronics Inc. et al 2:16-cv-00439-JRG-RSP

Semcon IP Inc. v. Texas Instruments Incorporated 2:16-cv-00440-JRG-RSP

Semcon IP Inc. v. ZTE Corporation et al 2:16-cv-00441-JRG-RSP

Marshall-based Semcon is the plaintiff.

It seeks to stop what it asserts to be infringement of U.S. Patent Nos. 7,100,061; 7,596,708; 8,566,627; and 8,806,247.

“The patents-in-suit generally cover methods for controlling the power used by a computer, specifically, the adjustment of the clock frequency and voltage supply to a processor to conserve processor power and extend battery life,” court papers state.

“The claims of the patents-in-suit generally call for the frequency generator and power management logic to be located on the processor itself, rather than in a separate component that would consume power.”

Semcon seeks unspecified monetary damages and a jury trial.

Its lead counsel is attorney Samuel F. Baxter of the law firm McKool Smith, P.C. in Marshall.
