Japanese Patent in the horological field
More than 700 patent applications in horology are published every year by Japanese companies.
Of this number, only a hundred applications become a granted patent and this several years later. Consequently, Japanese patent applications constitute a unique source of information complementary to the granted patent databases.
KOKAI is a technology monitoring service that covers recent Japanese patent applications in the field of horology.
Patent records in KOKAI are in English and contain a comprehensive abstract and a relevant figure. Patent records are classified by topics (mechanical watches, electronic watches, etc.) and subtopics (escapements, date indicators, etc.).
KOKAI is the essential complement to the Revue des Inventions Horlogères (Horological Patent Alerting Bulletin) - RIH.
