The Man with a Mill Stone About His Neck

The millstone about the neck of most young men in poor paying positions is lack of special training. It holds the man back while others go ahead. It handicaps him everywhere. You can throw off the burden. You can rise to one of the higher places in your present trade or profession. You can qualify for a more congenial occupation and better salary? If you have the will the way is easy. The first step is to write to us - stating which of the positions named below you desire to qualify for.

We will tell you how you can, without loss of time and at small expense, qualify yourself for the position you want. We will also send you our booklet, "1001 Stories of Success" which proves all that we claim.

Patents

The Wealth of Nations

A Patent gives you an exclusive right to your invention for a term of seventeen years. You can sell, lease, mortgage it, assign portions of it, and grant licenses to manufacture under it. Our Patent system is responsible for much of our industrial progress and our success in competing in the markets of the world. The value of a successful Patent is in no degree commensurate with the almost nominal cost of obtaining it. In order to obtain a Patent it is necessary to employ a Patent Attorney to prepare the specifications and draw the claims. This is a special branch of the legal profession which can only be conducted successfully by experts. For nearly sixty years we have acted as solicitors for thousands of clients in all parts of the world. Our vast experience enables us to prepare and prosecute Patent cases and Trade Marks at a minimum of expense. Our work is of one quality, and the rates are the same to rich and poor. Our unbiased opinion freely given. We are happy to consult with you in person or by letter as to the probable patentability of your invention.
