Patent Busting Project Start forming your patent busting posses! Here are the EFF Patent Busting Project's ten most-wanted patents—the ones that pose the biggest threat to the public domain. Thanks to all of your submissions in the patent busting contest, we've identified ten of the worst Internet and software-related patents in the U.S. What makes these patents among the worst of the bunch? Try the fact that their owners are threatening and filing suits against small businesses, individuals and nonprofits, not to mention the threats to free expression and innovation that each of them pose. From here on out, EFF's team of lawyers and technologists will be tracking down prior art and preparing to petition the Patent and Trademark Office for revocation of these offenders' patents. To do this, we'll need your help to find prior art and get the busting process underway. Check out each patent and see how you can help bust it by clicking on the images below.
