Patents are obtained on the best terms.
A special notice is made in the SCIENTIFIC AMERICAN of all
inventions patented through this Agency, with the name and residence
of the Patentee. By the immense circulation thus given, public
attention is directed to the merits of the new patent, and sales or
introduction often easily effected.
Any person who has made a new discovery or invention can ascertain,
free of charge, whether a patent can probably be obtained, by writing
to MUNN & Co.
We also send free our Hand Book about the Patent Laws, Patents,
Caveats, Trade Marks, their costs, and how procured. Address
