Prior to the 1999 American Inventors Protection Act (AIPA), accurate statistics of the success rate of invention promotion firms were difficult to come by. Nonetheless, as a result of certain legal actions taken against some of these firms, overall success rates have come to light. One such firm, Davison Associates, disclosed that of 900 ideas where a client had a prototype built of their invention at an average cost of $11,000, only 30 of those inventions were licensed within 6 months.
