ACHIEVEMENTS

We deal with cutting-edge technologies on a daily basis, have filed numerous applications in both Japan and foreign countries, and have dealings in over 90 countries across the globe

We have so far handled many filings of domestic applications not only from domestic clients but also from foreign clients. Also, we have abundant experience in handling foreign filing applications including PCT international applications. In filing foreign applications, it is necessary to draft high-quality English specifications. At SIKs, we prevent technical mistranslations by our patent attorneys directly checking the English translation of patent specifications. Furthermore, we appoint suitable foreign agents who are familiar with the corresponding technical field, and our patent attorneys personally prepare correspondences, which contain technical subject matter, to be frequently exchanged with foreign agents. We endeavor to work closely with our foreign agents by giving them appropriate instructions.

Administrative staff department

At SIKs, our patent attorneys and administrative staff work closely together, and we believe that we can provide the best services to our clients based on this close teamwork between our patent attorneys and administrative staff. SIKs’ administrative staff department consists of the following three departments; namely, the domestic application department which mainly handles affairs related to filings of domestic applications and PCT applications, the foreign application department which mainly handles affairs related to filings of foreign applications, and the department which handles general affairs, accounting and human affairs. Each department has 10 to 15 competent staff members, and a majority of the staff members of each department consists of persons with 5 to 10 years of experience who are familiar with various affairs and procedures. The general affairs group has two IT engineers who ensure that our electronic information system can be operated safely and securely on a daily basis.

Office management system

At SIKs, we use our self-developed office management system “S-PAT®” not only to manage procedural deadlines and cases, but also for centralizing various business affairs such as the automatic creation of various postal matter, management of various documents as electronic information, and accounting operations including the handling of billings from foreign agents.
