Intellectual Property Registration

Atsumi & Sakai’s dedicated intellectual property registration team is led by partners recognized by independent commentators as leading IP practitioners in the field, who have extensive experience in IP registration.  We assist with registrations of:

  • Patents

We also advise on the protection of IP rights that are not covered by the IP registration regime.

Our team can do business and draft documents in Japanese, English, German, Mandarin, Hindi, Korean, and Marathi, and provides services around the clock through our global affiliated offices.
