- According to Shepherd, ‘…patents are a notoriously weak measure. Most of the eighty thousand patents issued each year are worthless and are never used. Many are of moderate value and a few are bonanzas. Still others have negative social value. They are used as “blocking” patents to stop innovation, or they simply are developed to keep competition out’
