Reputation for quality
SUGIMURA has earned an international reputation for quality in Japanese IP prosecution. SUGIMURA attorneys are not only skilled in the nuances of IP law and regulation, they also possess technical and practical expertise across every technology and business sector. SUGIMURA attorneys have years of experience working in major corporations as researchers, engineers, IP professionals and in-house counsel. Some have also served for decades at the Japan Patent Office (JPO). This combination of expertise allows SUGIMURA to understand the perspectives of corporations and patent and trademark owners, as well as that of the JPO, enabling it to deliver practical and effective solutions to further clients’ business objectives.
While most Japanese IP firms outsource translation work, SUGIMURA retains in-house translators to strengthen the quality of cross-border prosecution and ensure the technical accuracy and legal appropriateness of translated documents. The translation department is skilled in Japanese, English, German and Chinese.
In addition to in-house translators, SUGIMURA has in-house IP draftspersons. The inclusion of in-house translators and draftspersons increases quality, ensures congruency and avoids time delays in IP prosecution.
SUGIMURA represents both Japanese and international clients pursuing patent, design and trademark protection in Japan. This clientele ranges from individual inventors and start-ups to well-established academic institutions and multinationals from all sectors of the global economy, including automotive, aviation, transportation, food and beverages, consumer goods, fashion, sports and recreation, chemical, software and hardware, electronics, e-commerce, biotechnology, pharmaceuticals, medical, energy, agriculture, entertainment and media, construction, semiconductors, optics, telecommunications and manufacturing.
SUGIMURA has significant experience providing legal advice to international clients concerning patent and trademark prosecution and enforcement in Japan.
