OUR MISSION

In January of 2026, SOEI marked the 40th anniversary since its establishment, and now embarks on a new chapter as Soei Intellectual Property Law.

After decades of pioneering leadership by our founder, Yoshiki Hasegawa, the baton now passes to us, Yasuki Yanagi and Takeshi Nakatsuka, as the new co-presidents of SOEI.

This transition to a new generation, along with the corporate reorganization, is not just a change in leadership but also represents, so to speak, a “second founding” of our firm. We now change course from a management model built on dynamic leadership by our founder to more of a team-based approach with six management board members of diverse specialties who collaborate in overseeing and steering the organization.

Although its structure changes, SOEI’s “DNA” that we have resolved to preserve yet remains.

We thus continue with our dedication to protecting our clients’ intellectual property as the “Unrivalled Experts of IP” and consistently delivering excellence that garners their highest praises.

Guided by principles that have defined SOEI since its founding, we shall deliver ever-better expertise by expanding on the foundation that our founder has fostered, of every one of our professionals building on unique insight and acting decisively.

Our in-house legal department has also been reorganized as the affiliated Soei Shitara IP Law Firm. Although now separate organizations, we shall collaborate ever more closely, in maintaining and reinforcing an integrated system for robust support of both the technical and legal aspects of our clients’ IP management.

We carry on with our founder’s resolve to “provide enduring value as an organization” as entrusted to us and, with the entire firm united, remain committed to continuous evolution.

We invite you to look forward to the renewed and reinvigorated Soei Intellectual Property Law, and appreciate your continued—and even greater—support and encouragement going forward.
