Foreign Patents.—After you have applied for a patent on your invention in the United States you should take out patents in foreign countries. Sometimes indeed you will find a more ready sale abroad for your invention, or the product of your invention, than you will right here at home. In many of these countries a yearly tax is also charged by the government. The costs given below for each country include both the government and the attorney’s fees.
Dominion of Canada.—In Canada a preliminary protection may be secured for one year. A patent is issued for 6 years and at the expiration of that time the patent may be extended for 6 years more and then for another 6 years, making 18 years in all.
| Preliminary protection | $ 5 |
| Patent for 6-year term | 45 |
