The actual work of inventing is a wively small part of the long rocess that leads to success. An inventor, to be successtul, must be far more than a mechanical innova- tor.

As a result of the necessity for the inventor to protect his interests on the thorny path which leads to a big reward, a large army of specialists s grown up known as patent at- torneys, who make a business of pilot- ing the inventor through the mazes of the law. There are about 10,000 patent attorneys, mainly in the cities of New York, Chicago and Washing- All who are qualified are regis. d at the Patent Office. Rigid supervision has falled to pre- vent the systematic swindling of a |1arze group of unsuspecting persons who believe they have an invention. Inventors, as a class, are instinctively suspicious.
