Patent Troll Goes After Notebook Cooling 131
An anonymous reader writes "If you are manufacturing notebooks and you are using hardware that needs to be cooled down occasionally, you may be in the crosshairs of IPventure, which claims patent rights to an approach that is common in all notebooks today. For now, the company appears to be establishing its case by suing Fujitsu and Lenovo over the use of its invention in the Lifebook and Thinkpad series of products."

While this clearly has been a novel approach, it is questionable if it was novel when the original patent claimed by IPventure was filed on June 22, 2007 and there may be a good chance that prior art could invalidate both of its patents.
It's almost the opposite, actually. They sued almost as soon as one of the patents was awarded.
