and our success in competing in the markets of the world.
The value of a successful Patent is in no degree commen-

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 profes-
sion which can only be conducted successfully by ex-
perts. For nearly sixty years we have acted as solicitors
for thousands of clients in all parts of the world.
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.
