The Oregonian is running a article about a company, Exit Exchange, that claims to have invented the pop-under ad and is currently in the process of patenting it. According to the article the company hopes to collect royalties from other companies using pop-under ads. Are two lines of javascript worthy of a patent? On the other hand, this is one stupid patent. I’d love to see it held up in court, just so that the licensing fees could discourage advertisers from attacking their potential clients.
