Zordak writes "According to Law 360, H.R. 845, the 'Saving High-Tech Innovators from Egregious Legal Disputes' (SHIELD) Act of 2013 would require non-practicing entities that lose in patent litigation to pay the full legal costs of accused infringers. The new bill (PDF) would define a 'non-practicing entity' as a plaintiff that is neither the original inventor or assignee of a patent, and that has not made its own 'substantial investment in exploiting the patent.' The bill is designed to particularly have a chilling effect on 'shotgun' litigation tactics by NPEs, in which they sue numerous defendants on a patent with only a vague case for infringement. Notably, once a party is deemed to be an NPE early in the litigation, they will be required to post a bond to cover the defendants' litigation costs before going forward."
