Patents in Brazil and Mexico.

Until quite recently, considerable difficulty has been experienced by inventors in obtaining patents in both Brazil and Mexico. The requirements of the officials of these countries caused much bother and delay, and the expenses of a patent corresponded therewith.

But there no longer exists that trouble and delay in obtaining patents in either country. The proprietors of this paper have perfected arrangements with resident professional gentlemen in both countries, Brazil and Mexico, which enables them to obtain patents within reasonable time and at reasonable cost.

These two countries embrace an enormous area of territory, and makers of improved machinery and implements are now finding a market for their products in those countries.

The cost need no longer deter inventors from obtaining patents in either Brazil or Mexico.

FOREIGN PATENTS.

Their Cost Reduced.

The expenses attending the procuring of patents in most foreign countries having been considerably reduced the obstacle of cost is no longer in the way of a large proportion of our Inventors patenting their inventions abroad

=CANADA.=--The cost of a patent in Canada is even less than the cost of a United States patent, and the former includes the Provinces of Ontario, Quebec, New Brunswick, Nova Scotia, British Columbia, and Manitoba.

The number of our patentees who avail themselves of the cheap and easy method now offered for obtaining patents in Canada is very large, and is steadily increasing.

=ENGLAND.=--The new English law, which went into force on Jan. 1st. 1885, enables parties to secure patents in Great Britain on very moderate terms. A British patent includes England, Scotland, Wales, Ireland and the Channel Islands. Great Britain is the acknowledged financial and commercial center of the world, and her goods are sent to every quarter of the globe. A good invention is likely to realize as much for the patentee in England as his United States patent produces for him at home, and the small cost now renders it possible for almost every patentee in this country to secure a patent in Great Britain, where his rights are as well projected as in the United States.

=OTHER COUNTRIES.=--Patents are also obtained on very reasonable terms in France, Belgium, Germany, Austria, Russia, Italy, Spain (the latter includes Cuba and all the other Spanish Colonies), Brazil, British India, Australia, and the other British Colonies.

An experience of =FORTY= years has enabled the publishers of THE SCIENTIFIC AMERICAN to establish competent and trustworthy agencies in all the principal foreign countries, and it has always been their aim to have the business of their clients promptly and properly done and their interests faithfully guarded.

A pamphlet containing a synopsis of the patent laws of all countries, including the cost for each, and other information useful to persons contemplating the procuring of patents abroad, may be had on application to this office.

=MUNN & CO.,= Editors and Proprietors of THE SCIENTIFIC AMERICAN, cordially invite all persons desiring any information relative to patents, or the registry of trade-marks, in this country or abroad, to call at their offices, 361 Broadway. Examination of inventions, consultation, and advice free. Inquiries by mail promptly answered.

We warrant these patent saws to be very much better than any other kind in market. They will come into more general use than files when once introduced. Hardware dealers every where will furnish them on request.
