In recent years intellectual property has been getting more and more important. To engage this emerging trend, we established
“AICHI,Takahashi,Iwakura & Associates” with great dedication, a strong sense of responsibility, and over 20 years experience as Takahashi Patent Office and Takahashi,Iwakura & Associates in April 2007. This firm was instituted and renamed from Takahashi,Iwakura & Associates. We started as Takahashi Patent Office set up by Yoshiyasu Takahashi in 1987. Since then, we have made efforts to provide the best possible services for our clients with the catch phrase “Making Intellectual Property Bring Up Dreams”. This attitude must not change now or in the future.
The first part of the firm name “AICHI” means not only AICHI prefecture but also love and intelligence. “AI” means love, and “CHI” means intelligence in Japanese. We will continue to devote our AI(love) into your CHI(intelligence) in our usual work, and protect important your intellectual property.
In the days ahead, though your needs might change with your social or economic situation, we will show our flexibility and adjust accordingly.
We swear to do our best to earn your trust.
