Start-up claims network injunction against Longhorn

Summary: Microsoft's Chimney networking architecture could go up in smoke if a small Californian company is successful

A small Californian company says it has been granted a preliminary injunction preventing Microsoft from incorporating a patented networking method into future versions of Windows.

Alacritech said on Wednesday that the injunction blocks Microsoft from using its Chimney architecture, which Alacritech said Microsoft plans to include in both a "scalable networking pack" for Windows Server 2003 and in Longhorn, the next version of Windows.

Microsoft's Chimney software provides support for hardware that accelerates networking using the TCP/IP standard, which underlies the Internet and countless private networks. Microsoft designed Chimney to minimise compatibility issues with existing computing technology.

"After Alacritech discovered that Microsoft Chimney is based on intellectual property that we developed, patented and own, we offered Microsoft a licence," Alacritech chief executive Larry Boucher said in a statement. "Microsoft rejected licensing terms that would be acceptable to us. We were forced to sue Microsoft to stop them from continuing to infringe, and inducing others to infringe, on our intellectual property rights."

Microsoft spokeswoman Stacy Drake reiterated the company's position that its Chimney technology was "independently developed."

"As an intellectual property company, we invest heavily in research and development and are committed to respecting the intellectual property rights of others," Drake said.

Alacritech sued Microsoft last August, alleging that Chimney infringes on two Alacritech patents, both titled "protocol processing stack for use with intelligent network interface device."

According to Alacritech, Microsoft first discussed plans for Chimney at a hardware conference in the spring of 2003. Alacritech said it offered to license its technology to Microsoft that October, but was rebuffed in April 2004, prompting it to file its suit.

An Alacritech representative declined to comment beyond the company's press release.

    Yea Yea Yea i think we have all heard that one too many times form the M$ Corp theft machine.

    They could not develope a thing let alone a new networking protocol ect .

    I will say it once again WE Desperatley need to review ALL M$ Corp code old and new as i believe it is packed with bit's of open source GPL'ed code It is even more important we see the entire Longhorn codebase with absolutley NO EXCEPTIONS AT ALL every single letter of it .

    You can be fairly comfortable that the only parts of any M$ Corp products that actually WORK are the bits that have been stolen from the Open Source Community

    I know there are a lot of you out there that dissagree but the fact remains we have got to do it ..
