A US Federal District Court ruled that 26 of Xircom's products, including its RealPort modems, are likely to infringe on technology patented by 3Com.
Intel, in response, has filed a motion to stay the injunction until an appeal is heard, Intel's UK press relations manager Graham Palmer said.
"Intel is not a party to this, nor are any Intel products involved. It's a legacy matter that predates the acquisition," he said.
However, Palmer stressed that the RealPort products are coming to the end of their life cycle anyway. "RealPort has been a strong performer for many years but it's now past its technological maturity," he said.
3Com filed the complaint in February 2001, one month before Intel bought Xircom.
