CAVEATS, COPYRIGHTS, TRADE MARKS, ETC.

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, THE SCIENTIFIC AMERICAN HAND

BOOK, an elegantly illustrated pamphlet of 48 pages, 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.

_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. Address
