Patent Infringement Exemption for Research?

cheesedog writes "It has been said that 1/5th of all scientific research projects in the U.S. are currently being stifled by patent claims. Well, it looks like the Senate has taken notice, with a recent proposal that has made it into the PACE Education and Research Act that could extend an exemption from patent litigation for scientific research. The Act also proposes treating specialized industries (such as software and business methods) differently than traditional patent areas."
