THE OLDEST AGENCY FOR ELICITING PATENTS IN THE UNITED STATES.

_THIRTY YEARS' EXPERIENCE._

MORE PATENTS have been secured through this agency, at home and

abroad, than through any other in the world.

They employ as their assistants a corps of the most experienced men as

examiners, specification writers, and draughtsmen, that can be found,

many of whom have been selected from the ranks of the Patent Office.

SIXTY THOUSAND inventors have availed themselves of Munn & Co.'s

services in examining their inventions and procuring their patents.

MUNN & CO., in connection with the publication of the SCIENTIFIC

AMERICAN, continue to examine inventions, confer with inventors,

prepare drawings, specifications, and assignments, attend to filing

applications in the Patent Office, paying the Government fees, and

watch each case, step by step, while pending before the examiner. This

is done through their branch office, corner F and 7th Sts.,

Washington. They also prepare and file caveats, procure design

patents, trade marks, and re-issues, attend to rejected cases

(prepared by the inventor or other attorneys), procure copyrights,

attend to interferences, give written opinions on matters of

infringement, furnish copies of patent business, both in this and in

foreign countries.

A special notice IS made in the SCIENTIFIC AMERICAN of all inventions

patented through this agency, with the name and residence of the

patentee. Patents are often sold, in part or whole, to persons

attracted to the invention by such notice.

Patents obtained in Canada, England, France, Belgium, Germany, Russia,

Prussia, Spain, Portugal, the British Colonies, and all other

countries where patents are granted, at prices greatly reduced from

former rates. Send for pamphlet pertaining specially to foreign

patents, which states the cost, time granted, and the requirements for

each country.
