For Twenty-five years, MUNN & CO. have occupied the leading position
of SOLICITORS OF AMERICAN AND EUROPEAN PATENTS. During this
long experience they have examined not less than _Fifty Thousand
Inventions_, and have prosecuted upwards of THIRTY THOUSAND
APPLICATIONS FOR PATENTS. In addition to this they have made, at the
Patent Office, _Twenty-Five Thousand_ Special Examinations into the
novelty of various Inventions.
The important advantage of MUNN & CO.'s American and European Patent
Agency is that the practice has been tenfold greater than that of any
other agency in existence, with the additional advantages of having
the aid of the highest professional skill in every department and a
Branch Office at Washington, that watches and supervises cases when
necessary, as they pass through Official Examination.
