Synopsis of Foreign Patent Laws, showing the cost and

method of securing patents in all the principal coun

tries of the world. American inventors shonid bear In

mind that, as a general rule, any invention that is vain-

able to the patentee in this country is worth equally as

much in England and some other foreign countri—

Five patents—embracing Canadian. English, German,

French, and Belgian—will secure to an inventor the ex

clusive monopoly to his discovery among about osi

hundred and fiftt .MILLIONS of the most intelligent

people in the world. The facilities of business and

steam communication arc such that patents can be ob

tained abroad by our citizens almost as easily as at

borne. The expense to apply for an English patent Is

$75; German, $100: French, $100; Belgian, $100; Cana

dian, $50.Copies of Patents.—Persons desiring any patent

issned from 1836 to November 26. 1867, can be supplied
