Every company has strengths. But those strengths often go unrecognized by the company itself. We help you see them, and use your IP strategically.
Every company has its own strengths, yet they often go unrecognized as simply ordinary. By recognizing the intellectual assets behind those strengths and using the resulting IP strategically, a company can gain a competitive edge. We help clients see their strengths and build strategies that put their intellectual assets to work.
It is increasingly hard to secure profit through domestic business alone. Depending on overseas production and multi-country trade, planning foreign patents, trademarks, and know-how protection from a broad perspective is essential. Working with external experts, we build strategies that leverage Japan's strengths worldwide.
Invention grows from the wish to improve life; a brand rests on trust. Intellectual property is, in essence, a property of the heart. We work with integrity to carry that value forward so that society may grow.
Innovation comes not from control or expectation but from a free mind. We Japanese have absorbed other cultures and built our own. To make the most of that trait, we cultivate the ground for innovation through a human network of people with different backgrounds — in R&D, product planning, distribution, and more.

Just as a tree (樹) drives its roots deep into the earth to grow naturally, we believe that Intellectual Property (知財)—which is essentially the "wealth of the mind"—must also take root in society to deliver true value. With this ultimate goal of cultivating growth (樹) in mind, we approach every case and client with the utmost sincerity and professional integrity (誠).
To be a guide who spreads to the world the “treasures” born of Japanese values — values shaped through dialogue with nature — we coined the word “Seiju” (誠樹) and wrote it as “Seiju” so that people abroad can understand it too.
The logo depicts the letter “S,” meaning sincerity("Sei"誠), rooting into the soil of the Innovation Network and growing naturally like a tree.

On-site wisdom, technology, sensibility, and a culture of craftsmanship — if business results are the crop, protecting the soil that grows them is what leads to Japan's future. We protect a sensibility that resonates with nature, in the form of IP, for the next generation.
