Why has America stopped inventing? That’s the provocative title of a book by Darin Gibby. Gibby’s a patent lawyer and points out that Americans invent less than half of what we did a century ago. Half. Why? Are we less creative then we were 100 years ago? Gibby says the problem lies in one place and one place only – The US Patent system. He tells Anne Strainchamps the current system has got to go.
