Senators delivered a potential deathblow to patent reform on Wednesday as the Judiciary Committee postponed work on the tech industry’s top legislative priority. Senate Judiciary Committee Chairman Patrick Leahy said weeks of negotiations on a compromise had reached a dead end and announced he was yanking the bill from the panel’s legislative agenda. “I have said all along that we needed broad bipartisan support to get a bill through the Senate,” Leahy said in a statement.
