Messrs. Munn & Co., in connection with the publication of the
SCIENTIFIC AMERICAN, continue to examine Improvements, and to act as
Solicitors of Patents for Inventors.
In this line of business they have had OVER THIRTY YEARS' EXPERIENCE,
and now have _unequaled facilities_ for the preparation of Patent
Drawings, Specifications, and the Prosecution of Applications for
Patents in the United States, Canada, and Foreign Countries. Messrs.
Munn & Co. also attend to the preparation of Caveats, Trade Mark
Regulations, Copyrights for Books, Labels, Reissues, Assignments, and
Reports on Infringements of Patents. All business intrusted to them is
done with special care and promptness, on very moderate terms.
We send free of charge, on application, a pamphlet containing further
information about Patents and how to procure them; directions
concerning Trade Marks, Copyrights, Designs, Patents, Appeals,
Reissues, Infringements, Assignments, Rejected Cases, Hints on the
Sale of Patents, etc.
_Foreign Patents_.--We also send, _free of charge_, a Synopsis of
Foreign Patent Laws, showing the cost and method of securing patents
in all the principal countries of the world. American inventors should
bear in mind that, as a general rule, any invention that is valuable
to the patentee in this country is worth equally as much in England
and some other foreign countries. Five patents--embracing Canadian,
English, German, French, and Belgian--will secure to an inventor the
exclusive monopoly to his discovery among about ONE HUNDRED AND FIFTY
MILLIONS of the most intelligent people in the world. The facilities
of business and steam communication are such that patents can be
obtained abroad by our citizens almost as easily as at home. The
expense to apply for an English patent is $75; German, $100; French,
$100; Belgian, $100; Canadian, $50.
_Copies of Patents_.--Persons desiring any patent issued from 1836 to
November 26, 1867, can be supplied with official copies at reasonable
cost, the price depending upon the extent of drawings and length of
specifications.
Any patent issued since November 27, 1867, at which time the Patent
Office commenced printing the drawings and specifications, may be had
by remitting to this office $1.
A copy of the claims of any patent issued since 1836 will be furnished
for $1.
When ordering copies, please to remit for the same as above, and state
name of patentee, title of invention, and date of patent.

patents sent free. A handsomely bound Reference Book, gilt edges,
contains 140 pages and many engravings and tables important to every
patentee and mechanic, and is a useful hand book of reference for
