Intel Accuses Digital Of Patent Violations

Intel Corp., turning up the heat in a legal dispute with Digital Equipment Corp., has filed a countersuit accusing Digital of infringing its patents.

The allegations in the suit filed in federal court on Tuesday are similar to those made earlier by Digital against Intel.

Intel, the top maker of computer chips, accuses Digital of infringing 14 Intel patents ranging from microprocessor architecture to chip manufacturing.

Digital, Intel claims, uses that technology throughout its product line.

But Digital called the countersuit “a typical step for a company that has been sued for patent infringement.”
