Yes, and the Japanese version, but it boils down to ease of prosecution.

In general, an application for a patent must be filed, and a patent shall be granted and enforced, in each country in which you seek patent protection for your invention, in accordance with the law of that country. In some regions, a regional patent office, for example, the European Patent Office (EPO) and the African Regional Intellectual Property Organization (ARIPO), accepts regional patent applications, or grants patents, which have the same effect as applications filed, or patents granted, in the member States of that region.

Further, any resident or national of a Contracting State of the Patent Cooperation Treaty (PCT) may file an international application under the PCT. A single international patent application has the same effect as national applications filed in each designated Contracting State of the PCT. However, under the PCT system, in order to obtain patent protection in the designated States, a patent shall be granted by each designated State to the claimed invention contained in the international application. Further information concerning the PCT is available.

Procedural and substantive requirements for the grant of patents as well as the amount of fees required are different from one country/region to the other. It is therefore recommend that you consult a practicing lawyer who is specialized in intellectual property or the intellectual property offices of those countries in which you are interested to get protection. A list of URLs and a directory of national and regional intellectual property offices are available.
