Judge Tena Campbell of the US District Court for the District of Utah, on 25 July imposed a preliminary injunction to prohibit the manufacture or sale in the US of Xircom's RealPort mobile network adapters.
On Thursday (1 August), 3Com filed an Order to Show Cause, claiming Intel was still offering the products for sale on its Web site and through other channels. Judge Campbell denied a motion by Intel to stay the injunction.
3Com claims the RealPort products violate a 3Com patent. It sued Xircom in May 2000 and asked for the preliminary injunction in February 2001. Intel completed its acquisition of Xircom in March of that year. Xircom is now an Intel brand.
The 26 products at issue in the case are network adapters for a Type III PC Card slot, which is found on most notebook PCs. They can be equipped with Ethernet, phone line and other types of physical interfaces. Because the physical ports are integrated into the PC Card, there is no need for a dongle, or short cable to connect the port component with a PC Card.
Xircom's products use an electrical contact that infringes a 3Com patent, according to 3Com spokesman Robert Glazier. 3Com applied for the patent in August 1997 and it was issued to 3Com in November 2000, according to the Web site of the US Patent Office.
Intel has complied fully with the preliminary injunction and believes 3Com's suit has no merit, according to Intel spokeswoman Christine Chartier.
