ich are offered for sale by their
respective patentees, who in many cases have no definite lines to pursue
in negotiating their patents; many realizing little or nothing from
their inventions through careless or bad management, while others,
through incompetency, drift into the hands of unscrupulous
patent-selling agents only to be swindled.

The numerous inquiries from patentees seeking practical, reliable, and
up-to-date information as to the best and most successful methods of
realizing from the product of their ingenuity, has led the author, after
due deliberation, to prepare and present this work to the American
inventor, with a view of supplying a long-felt want, with the hope that
it will save them many expensive experiments in handling their patents,
and advance them on the road to success.

It has been the endeavor of the writer to cover briefly every subject
that is usually encountered by patentees in disposing of their patents,
not only in the matter of selling, but also in the equally important and
perplexing questions of arriving at the value of patents, legal forms,
statistics, etc., etc.

Realizing that the work may be deficient in many respects, the hope that
it will prove instructive, and the belief that it contains many
practical pointers for patentees is still entertained by

THE AUTHOR.
