"The US Senate will vote on two bills that, if passed, will entrench software patents even further in the United States. The Patent Eligibility Restoration Act (PERA), sponsored by Senator Thom Tillis, seeks to "clear the legal landscape" surrounding patents, but will effectively make obtaining software patents even easier than before. Meanwhile, the Promoting and Respecting Economically Vital American Innovation Leadership Act (PREVAIL) Act, sponsored by Senator Christopher A. Coons, would severely limit how the public can challenge wrongly granted patents at the patent office."
