Tomohiko Kurosumi

We established “Crescendo Patent Firm” in Kurashiki City, Okayama Prefecture, in order to help our clients make effective use of their intellectual property for significant development.
This wish is also reflected in the name of the office. (“Crescendo” is the name of the musical symbol meaning “progressively louder”).

We provide services on patents, designs, trademarks and other matters for clients from all over Japan….
