Recently, the surroundings of agriculture have changed greatly in various aspects.
These changes are not limited to ones derived from environmental factors such as climate change. These changes also include technical progresses such as introduction of Artificial Intelligence (AI) and Information Communication Technology (ICT), and changes in system, such as effects of trade agreements, revisions to agriculture-related laws including the seeds law and the seedlings law. Such changes occur daily.

However, regardless of how greatly the surroundings of agriculture change, what are always positioned at the center of agriculture are living organisms and basic technologies for growing them. Japan, which has rich seasonal changes, is the third in the number of plant variety registration applications, and has an unsurpassed advantage of broad range of breeders.
What is required for developing agriculture as agribusiness by mainly using this advantage and at times using changes in the surroundings of agriculture as wind at the back? Sharing of values and differentiation of values will be surely considered as important more and more. Intellectual properties will play a great role in this regard.

(Former website) Plant Variety Registration Consultation: Introduction of Contents


Since new plant variety and breeder's right has become clearly stated in the Intellectual Property Base Act, amendments have been made in the Seeds and Seedlings Law and also significant changes have been made to the policies of the Ministry of Agriculture, Forestry and Fisheries of Japan. The situation is such that plant variety guardians are allocated in the Incorporated Administrative Corporation National Center for Seeds and Seedlings.

The number of applications for variety protection have shown an increase as below, and the Ministry of Agriculture, Forestry and Fisheries of Japan are aiming for the number of 2,000 applications yearly by the year 2010.

In addition, they are also aiming for the shortening of average examination period, down to 2 and a half years by the year 2008.

I would like to introduce the Plant Variety Protection system with cooperation of our support station and patent engineers. "HARAKENZO more " hope this would help your understanding towards the Plant Variety Protection system.
