Japan patents

Depending on the budget, it is recommended that patents be applied for in those countries where they will be marketed and manufactured. Due to this, applying in one country or another could depend on the nature of the invention, however it is always a good practice to evaluate the application in the most important economies and in the jurisdictions that file the most patent applications. Japan is one of these.

In this country we offer highly competitive prices. If you need additional information do not hesitate to contact us!.
