Technical
Fields
and Areas
of Expertise
We handle a wide range of advanced technical fields, with a focus on providing high-quality patent prosecution and strategic support tailored to each technology.

Chemistry field
We cover a wide range of technical fields in the chemical field, including organic materials, inorganic materials, resists, encapsulants, ceramics, and textile products.
Our patent attorneys, who have experience in research and development, accurately understand the background, structure, and experimental data of the technology, and design claims with an eye toward future business development.
In the chemical field, the strength of rights depends on the description of patent specifications and the use of data, so we are able to provide meticulous support using our specialized knowledge.
We also handle organizing elemental technologies such as raw materials, reactions, and products, as well as strategic applications for application inventions.

Material field
We also handle intellectual property strategies for cutting-edge technologies. We handle a wide range of inventions in cutting-edge fields, including new materials such as rubber materials, electronic materials, functional materials, molding materials, inorganic materials, battery materials, optical materials, glass, liquid crystal, metal materials, catalysts, adhesives, fluorescent materials, and dielectric materials.
In these materials fields, patent requirements are high hurdles, making accurate technical understanding and application strategies essential.
Taking into account field-specific issues such as functional features that cannot be expressed structurally, we will prepare specifications and formulate response strategies to favorably proceed with examination and patent acquisition.

Equipment and machinery related
We also handle applications in the peripheral technology and machinery fields, such as chemical facilities, laboratory equipment, and measuring instruments. For equipment and analytical equipment associated with chemical processes, it is important to design specifications based on an accurate understanding of the structure, function, and use. Utilizing our understanding of the technical background and know-how in application practice, we can flexibly handle applications and patent acquisition in complex technical fields.
Our Services
and Strategic Approach
Our Services
and Strategic
Approach
We offer a full range of patent services for foreign associates and companies, with an emphasis on precision, speed, and strategic alignment with Japanese patent practice.
Patent Filing in Japan
We handle priority claims based on foreign applications as well as PCT national phase entries. For chemical inventions, we focus on optimizing claim interpretation and specification wording to align with Japanese Patent Office (JPO) examination practices. This ensures that applications are accurately adapted to Japanese legal and technical standards, improving the likelihood of smooth prosecution.


Office Action Responses
Our Patent attorneys prepare strategic arguments and amendments from both technical and legal perspectives. We have extensive experience in handling issues that are common in chemical cases, including inventive step, support requirements, and use limitations. By leveraging our understanding of JPO examination trends, we provide tailored responses that strengthen the chances of grant.
Patent Specification Drafting and Translation
We create precise and legally sound patent specifications in both English and Japanese. Our team is highly skilled at translating complex chemical terminology, structural formulas, and functional expressions while maintaining consistency between languages. Every translation undergoes internal legal review to ensure accuracy and clarity suitable for international filings.
