Intel Corp says it has not ruled out taking IBM Corp to court over its plans to fabricate Cyrix Corp microprocessors and market them under its own name – Intel believes Cyrix does not have the right to manufacture chips at IBM’s facilities the its cross-licensing agreement with IBM, which does not allow for third-party manufacturing, but IBM said its lawyers thoroughly studied the issue and satisfied themselves that it will not have any bearing on the IBM-Cyrix agreement: a federal judge in Texas is expected to rule this summer on whether a company with an Intel patent cross-licence – such as IBM or SGS Thomson Microelectronics BV (see front) – can also make unauthorised Intel-like chips for Cyrix; IBM also has been in discussions to make the Pentium-like chip designed by NexGen Microsystems Inc, and says those talks are continuing; under IBM’s deal with Cyrix, it can derive standard cells from the parts – such as the iAPX-86 core that will go into the PowerPC 615.
