GREETINGS

Welcome to our website. SHIMADA & PARTNERS has been providing services related to the acquisition and management of patents, utility models, designs, trademarks, and other intellectual property services for over 40 years since Yoshikatsu Shimada established Shimada Patent Office in 1980.

Particularly in the field of trademarks, we have handled numerous cases both domestically and internationally, accumulating valuable experience. As a result, we have earned a strong reputation among clients worldwide as a trusted intellectual property firm with expertise in trademarks.

We excel in domestic and international trademarks, including applications for international registrations under the Madrid Protocol. Building a network to handle intellectual property matters worldwide is one of our core strengths.

Conducting comprehensive trademark searches as part of the pre-application process and drafting accurate lists of goods and services that align with clients’ business operations are areas where we truly shine. Our utmost dedication is to ensure clients achieve the optimal acquisition of trademark rights.

Furthermore, we are well-versed in all aspects of trademark procedures, such as submitting responses against office actions, filing various appeals, applying trademark renewals, and transferring trademark rights. We always approach these procedures from the standpoint of clients and provide them with the best possible proposals.

In the realm of securely protecting intellectual property rights, it is not always the large firms that consistently yield favorable results. Sometimes, smaller firms can prevail. SHIMADA & PARTNERS is a small firm and proud of it. Our firm, comprised of a few dedicated professionals, leverages the strength of being a compact entity to deliver prompt and accurate results for a variety of client demands. Since our establishment, this commitment to delivering tangible 'results' has strengthened our partnership with clients.

Moving forward, we remain committed as a unified team to provide our esteemed clients with high-level services. We sincerely appreciate your continued support and look forward to serving you. Thank you.
