A story of owls…

Owls, said to be the attendants of Athena, the Greek goddess of wisdom and skills, are also known as the symbol for academics, liberal arts, wisdom, and sages.

With the ability to see in darkness along with exceptional hearing, owls are also known as “forest sages” and “forest watchmen” that do not overlook small items or miss information, and have bright prospects.

In association with the owl likened to such symbol, to serve as a “watchman of intellectual property” in protecting the intellectual property of our clients, Yoshikawa International Patent Office, while incorporating the motif of an owl in the logo, will continue efforts with duties every day.
