Supplementary Note of Specific Infringement Lawsuit Counsel


Back when he was a university student, Ikuya Kameyama started looking at the research and development of discharge plasma equipment, including their design, operation, and maintenance, in conjunction with researching ion drive rocket engines for things like artificial satellites and planetary exploration spacecraft. Performing magnetic field calculations, plasma fluid calculations, ion trajectory calculations, and chemical reaction model calculations made him familiar with finite element method analysis, difference method analysis, and molecular dynamics methods.

Dr. Kameyama spent time studying abroad while a graduate student at the University of Tokyo. He received his M.S. and Ph.D. from conducting research on extending the service life of the hollow-cathode electron source used in ion drive engines, and also developed a calculation program designed to estimate the performance of ion extraction grids.

After received his Ph.D., he worked at the Electrotechnical Laboratory of Agency of Industrial Science and Technology (currently the National Institute of Advanced Industrial Science and Technology) as a Special Researcher of the Japan Science and Technology Corporation. At the laboratory, his work involved evaluating the performance of ECR plasma source designed for materials processing, and the development of time-of-flight mass analysis technology for sputtered particles through laser sputtering used in two-photon ionization technology.

Later, Dr. Kameyama joined the US company Ion Tech, Inc. where he worked in research and development. Drawing on his prior experience in the field, he worked on the development of ion beam sputtering equipment used for forming optical thin films, in-situ optical film monitors using lasers, and large ion equipment. As part of his work on establishing industrial technologies for manufacturing and technology transfer to the manufacturing division, he gained an understanding of client needs through consultations and was involved in training sessions the company provided at product delivery. He was also involved in creating training opportunities for helping employees to speak with customers, as well as the training of new employees.

While in the US, Dr. Kameyama received his Small and Medium Enterprise Management Consultant license in order to enrich his knowledge of business management. As an R&D researcher, he himself is an inventor. While helping with company rights acquisitions, he became qualified as a patent attorney, creating a research and development environment geared towards intellectual property protection.

After returning to Japan, he joined Asamura Patent Office, p.c., where his work involves patent applications (patent applications from abroad and for foreign countries). Constantly drawing on his prior work experience in patent rights acquisition and his linguistic abilities, he approaches matters from an inventor's point of view. In addition to regular prosecution-related work, Dr. Kameyama has been engaged in invalidity searches regarding the execution of rights, our in-house court-related case study group, internal and external circulations of revisions of Japanese IP-related laws, and so on.  Outside the regular work, Dr. Kameyama has been involved in International Activity Center of Japan Patent Attorneys Association to study practice and court decision in the US and to provide seminars on Japanese practices in the Exchange Group with AIPLA (American Intellectual Property Law Association).

My background experience is in ion-beam devices and ion-beam sputtering;  I am confident, however, that I can quickly respond to a wide variety of clients’ needs with my strength in mathematics and physics. Since I was in university, I have always wanted to gain as much experience as possible in technical business management, with a particular focus on project management because I was surrounded by the idea of proactively managing one's own work.

In regards to intellectual property work, I participate in the patent application process while maintaining an inventor's point of view, have the opportunity to be exposed to the differences in patent protection and similar patent functions in the US, Europe, and Japan, consider the differences between inventors, applicants, and proxies from various countries for foreign and domestic applications, and closely communicate with concerned parties in order to understand current conditions and take the best measures. I am certain that I can assist you with matters that require strong technical comprehension, management knowledge, and experience in intellectual property right protection (including overseas intellectual property right protection).
