Google's public policy blog has announced a "Patent Purchase Promotion" that is a simple, easy to use, and fast experimental marketplace for patents.
"Patent owners sell patents for numerous reasons (such as the need to raise money or changes in a company’s business direction). Unfortunately, the usual patent marketplace can sometimes be challenging, especially for smaller participants who sometimes end up working with patent trolls. Then bad things happen, like lawsuits, lots of wasted effort, and generally bad karma. Rarely does this provide any meaningful benefit to the original patent owner.
"So today we’re announcing the Patent Purchase Promotion as an experiment to remove friction from the patent market. From May 8, 2015 through May 22, 2015, we’ll open a streamlined portal for patent holders to tell Google about patents they’re willing to sell at a price they set. As soon as the portal closes, we’ll review all the submissions, and let the submitters know whether we’re interested in buying their patents by June 26, 2015. If we contact you about purchasing your patent, we’ll work through some additional diligence with you and look to close a transaction in short order. We anticipate everyone we transact with getting paid by late August."
