Cognex sues MVTec Software

Cognex Corp. of Natick said it is suing MVTec Software GmbH and MVTec LLC, its Cambridge-based US subsidiary, over claims of patent infringement.

Cognex designs, develops, manufactures, and markets machine vision sensors and systems.

According to its website, MVTec Software is headquartered in Germany.

In a complaint filed in the US District Court in Boston, Cognex alleges that MVTec's Halcon machine vision software infringes the claims of at least seven Cognex patents.

Cognex said it is asking the court to enjoin MVTec from making and selling the infringing software, and it is also seeking unspecified damages in compensation for past infringement.

Fuji America Corp., which sells semiconductor capital equipment that incorporates MVTec's Halcon software, is also named in the complaint, Cognex said.

Last week, Cognex said it won a patent lawsuit over Acacia Research Corp.
