Who’s a Patent Troll? You’ll be Surprised by the Answer
Nobody likes patent trolls, the “non-practicing entities” accused of filing lawsuits with questionable infringement claims aimed at extorting settlements from companies just trying to do business. A conference today in Washington, D.C. sponsored by Innovation Alliance — a group promoting a strong U.S. patent system — featured a panelist who would under some definitions be…

Computer System Built with Carbon Nanotube Circuitry
Engineers at Stanford University in California created a basic computer system of circuits made from carbon nanotubes rather than conventional semiconductors built on silicon. The team led by Stanford electrical engineering professors Subhasish Mitra and H.S. Philip Wong published its findings online today in the journal Nature (paid subscription required). As silicon semiconductors became smaller and packed more…
