Intel Sues Rival Over Microprocessor : Computers: Suit charges that Chips & Technologies' computer-on-a-chip mimics the functions of Intel's 386 model. The smaller firm denies infringement.

SAN FRANCISCO — Continuing an aggressive legal strategy aimed at fending off competition in key markets, Intel Corp. has filed a patent infringement suit against Chips & Technologies of San Jose, which has begun marketing a microprocessor, or computer-on-a-chip, that mimics the functions of Intel's 386 chip.

Texas Instruments on Monday confirmed that it had agreed to make 386 chips based on the Chips & Technologies design, and said that it would go ahead despite the lawsuit. Chips & Technologies designs computer chips but doesn't have its own production facilities.

Santa Clara-based Intel filed the suit Friday, less than a week after an arbitrator ruled that Advanced Micro Devices could continue selling a "clone" version of the 386 because Intel had breached a technology-sharing deal with AMD.

Unlike the AMD chip, however, the Chips & Technologies 386 is not a clone but rather uses a unique design to perform the same functions as the Intel chip. Chips said it took pains to avoid infringing on Intel patents and even had two intellectual property law firms oversee development of the product.

Still, many observers expected Intel to sue Chips eventually. AMD's success in winning as much as 30% of the 386 market may have made Intel even more eager to block another competitor. In the suit, Intel seeks an injunction against further infringement and a restraining order to prevent Chips from transferring its 386 technology to another company, such as Texas Instruments or other firms that might make the part for Chips.

In a separate suit, Intel also contends that Chips infringed on a patent for the 387, a math processor chip.

Chips Chairman and Chief Executive Gordon Campbell, who once worked at Intel and has had previous legal run-ins with the chip-making giant, said Monday that he is "surprised, to say the least" that Intel had filed suit.

Campbell said the two companies had been in negotiations over a collection of intellectual property issues, including the 386 and some Chips patents that the company says are used by Intel. He said he believed that the two companies had an agreement not to sue one another while discussions were under way.

An Intel spokeswoman confirmed that the two companies had been discussing a settlement.

Meanwhile, Intel is expected today to unveil new versions of its most powerful computerchips in an attempt to stay ahead of the clone makers. The company will introduce the 486 DX2microporcessor, which is designed to double the speed of the computer without a similar cost increase for computer buyers, according to Paul Otellni, an Intel vice president.
