In-Depth Review TG4G Review ·2026-06-26 · For reference only

Platform Positioning

This is the official website of Kato United Patent Firm in Japan, a professional legal service organization in the intellectual property field. Its core offerings cover application, protection and dispute resolution for intellectual property rights including patents, trademarks and industrial designs, with a focus on supporting the intellectual property strategic layout of Japanese companies.

Core Services

The firm provides end-to-end intellectual property services for clients in Japan and worldwide:

  • Domestic services include application agency for patents, trademarks, utility models and industrial designs, plus infringement assessment, opposition, invalidation trials, litigation, and prior art search. It also offers intellectual property consulting and patent mining services.
  • International services support international patent applications, overseas application process agency, support for overseas infringement cases, and international intellectual property strategic planning.

The firm specializes in intellectual property services for three major technical fields: electrical, mechanical, and optical, covering all technical categories including communications, semiconductors, software, security, and general machinery.

Suitable Use Cases & Access

The website only supports Japanese and English, with no Chinese interface. It is suitable for companies with demand for Japan-related or international intellectual property business to connect with the firm. Chinese users can directly access the official website to get information about the firm.

As a professional IP law firm, the official website clearly displays its business scope and firm philosophy, but does not publicly disclose specific pricing. Users need to contact the firm to get a customized quotation. Overall, it has a clear positioning and outstanding expertise in its vertical field, but it is not suitable for ordinary Chinese individual users with intellectual property application needs.
