Acacia's Microprocessor subsidiary settles patent infringement lawsuit with Texas Instruments


Acacia Research Corp (Nasdaq:ACTG), which owns a portfolio of patents in wide range of industries, said Friday that its subsidiary Microprocessor Enhancement Corp has settled a patent infringement lawsuit the company filed against Texas Instruments.

In April 2005, Microprocessor Enhancement filed a lawsuit relating to the company's architecture used to enhance pipeline processing speed, against Intel and Texas Instruments.

The settlement and license agreement with Texas Instruments resolves patent litigation pending review by the Court of Appeals for the Federal Circuit, Acacia said.

The lawsuit alleged patent infringement by Intel's Itanium line of microprocessors, and certain series of digital signal processors sold by Texas Instruments. The case, which was filed in the District Court for the Central District of California, concluded that Texas Instruments and Intel did not infringe on any patent claims.

In April 2008, the Federal Circuit affirmed the District Court's summary judgement, after which Microprocessor filed an appeal.
Microprocessor's architecture executes processor instructions conditionally, and later determines whether the instructions executed should be written back to memory. By doing this, processor speed can be enhanced significantly.

Acacia Research's subsidiaries control over 160 patent portfolios, covering technologies used in a wide variety of industries.
