Four years after it filed its first, and still unresolved, lawsuit against Intel, Intergraph is back in court claiming that once again the chip giant is stealing its patents with the recently announced Itanium processor.
In the latest suit filed this week, Intergraph is asserting once again that Intel is using its patented parallel instruction computing technology in the Itanium chip. It made the same claim against Intel when it launched the Pentium processor.
In the early 1990s, Intergraph was a leading supplier of workstations for engineers and developed the C5 Clipper chip that it intended to use in its own machines. Hoping to gain wider acceptance for the Clipper, Intergraph partnered with Intel in a relationship that subsequently went sour and resulted in a lawsuit.
Intergraph's efforts to turn the lawsuit into a broad class action attack on Intel's dominance failed, but the patent infringement suit is still winding its way through the courts in Intergraph's home state of Alabama.
The company's chip design history dates back to the early 1970s but, following the Intel debacle, it has abandoned the chip and systems business and morphed into a software and services company targeting the telecoms and government marketplaces.
No one from Intel was available for comment.
