SAN FRANCISCO Magma Design Automation Inc. has dropped assertions of infringement against Synopsys Inc. relating one of the patents involved in the companies' Delaware patent litigation.
Synopsys (Mountain View, Calif.) and Magma (Santa Clara, Calif.) are also involved in a separate patent litigation dispute here. The two cases involve different patents. Friday's development has no impact on the California case.
Synopsys said it is also is dedicating certain of its inventions pertaining to scan chain partitioning to the public domain. By doing so, Synopsys said it is focusing its claims against Magma in the Delaware intellectual property litigation.
"We are pleased that Magma is dropping these infringement claims," said
Brian Cabrera, Synopsys' general counsel. "In truth, we have difficulty
understanding why Magma made these assertions in the first place."
David Stanley, vice president of corporate affairs at Magma, said the company had said some time ago that it might withdraw some infringement claims after more thorough research.
"Four of our patents are still at issue in the Delaware case," Stanley said.
