Hot on the heels of Digital Equipment Corp.'s patent challenge, Intel is facing another lawsuit over its Pentium family of processors, this time from Cyrix.

Cyrix's lawsuit, filed yesterday in the US District Court for the Eastern District of Texas, concerns two patents that Cyrix received this week, according to a Cyrix statement. Digital's lawsuit, filed in Massachusetts on Monday, alleges Intel infringed on 10 patents related to technology in Digital's Alpha microprocessor.

Cyrix alleges that Intel's Pentium, Pentium Pro, and Pentium II chips infringe on one or both of those patents. It is looking to get a temporary and permanent injunction to stop Intel's alleged use of their technology, as well as damages and fees.

Intel and Cyrix officials could not immediately be reached for comment.

Intel's stock dropped 6 3/4 yesterday on the lawsuit news, to 152 3/8, while Digital's stock rose 2 1/4, to 35 3/8. Cyrix's stock was down 5/8 to 23.
