Machine Vision Patents Thrown Out

chalker writes "Cognex Corporation, the world's leading supplier of machine vision systems, announced today that the U.S. District Court in Las Vegas has ruled in favor of Cognex in its lawsuit against the Lemelson Medical, Education & Research Foundation. It held that the claims of 14 patents asserted by Lemelson are invalid and unenforceable , and not infringed by Cognex. Co-plantiffs included barcode reader manufacturers Symbol Technologies, Accu-sort Systems, and Zebra Technologies amongst others. These patents were classic "submarine" patents orginally applied for in 1954, but tied up in the patent office and changed over the next four decades to cover changes taking place in the machine vision field. Lemelson had threatened to sue numerous end-users, including Motorola and Ford, over the past two decades and had settled all of them out of court for over $1.5 billion in licensing fees. For once a judge has seen how ridiculous our patent system is."

Not the end of the road, but a start

This is only a District Court decision (District of Nevada) so it is not binding precendent elsewhere. But it will interesting to see if this is the beginning of a trend that eventually kills the major cash cow of the Lemelson foundation. The foundation's business model has been to sue everyone in sight (or at least everyone who makes image recognition systems) and then to offer a license on the patents for an amount less than the cost of defense. It's been a very effective strategy. But there are tons of other Lemelson lawsuits in the works, and I am sure the lawyers are all reading this decision very carefully tonight.
