About Patent Law in Japan

Patents in Japan are granted by the Japan Patent Office (JPO) and provide inventors with exclusive rights to their inventions for a certain period of time. The purpose of patents is to protect inventions and encourage innovation by granting inventors the right to exclude others from making, using, selling, or importing their patented inventions.

Why You May Need a Lawyer

A lawyer can help you navigate the complex patent application process, respond to office actions, enforce your patent rights against infringers, or defend against allegations of patent infringement.

Local Laws Overview

In Japan, patent protection is granted to inventions that are new, inventive, and industrially applicable. The patent term in Japan is 20 years from the filing date of the application. Japan also recognizes utility models and design patents, each with its own requirements and protection scope.

Frequently Asked Questions

1. How do I apply for a patent in Japan?
