Charges and General Information Relating to Patents: Including All the Principal Countries of the World (Classic Reprint), Author Unknown

The State may buy and use an invention which it deems useful, in the following countries; Patents for Communicated Inventions. - This is a strictly English procedure, and the practice is confined to Great Britain and a few of its Colonies.

Importation of Patented Articles. - None of the principal foreign countries, except France, Canada, Tunis, Turkey and Peru, make any restrictions as to the imports, tion of patented articles. In Canada, unless an extension of time is procured, the patented article must not be imported by the patentee, or by others with his knowledge or consent, after the expiration of one year from the issue of the patent. In the other countries patented articles must not be imported at all except under special permit. Such permit may usually be obtained for the importation of a single model or sample, at a cost of about $10. France and Tunis now belong to the International Union, how ever, and citizens or subjects of countries belonging to the International Union may now import into these countries without restriction, but others are prohibited from so doing under the penalty of forfeiture of the patent.

Marking of Patented Articles - It is not compulsory to place any mark upon articles to indicate that they are patented, except in Canada, where the Word Patented and the year of the date of patent must be stamped or engraved on each article, as Patented, 1887, or as the case may be; in Switzerland, where all patented articles must be marked with the Federal Cross (44) and the number of the patent, and in Mexico, where the word Patentado, the number and the date of patent must be marked upon all patented articles.
