The US Patent office has just issued Yahoo a patent for customizable web page. In 1997 Yahoo filed a patent for a “dynamic page generator” that allowed a user to save a page and then have that page generate customized information. Just stop for a second and think about all the websites that offer this service that are now in violation of Yahoo’s patent. Just to name a few Google, Amazon, Bloglines and just about every major corporations intranet portal. The real question now is whether Yahoo will attempt to enforce it’s patent and request payments for everyone that uses there patented technology.
