Clients Voices

With Kimura, their approach was to think about the patent application’s content together with us and then create it. At first, we described the invention broadly, then Kimura flushed out the details with us and crafted the patent to fit into Patent law to get maximum protection.

This way was beneficial for us, and it took less time than expected. From the start, and at every step, Kimura responded promptly. They had a strong will to quickly file our patent and under the “first to file” principle.

When we asked Kimura to file our patent application, they studied our invention and considered it together with us. We described the broad idea and the concept of the invention based on the flush, and then they modify it into the invention which fit the patent law. This is very helpful for us SMEs.

Also, the duration from request to application is very short. Whenever we make a request, we feel their powerful will to file the patent application ASAP under the “First to file” principle.
