Sample of Japanese Patent Search: Slot Machine

A slot machine is a casino gambling machine with three or more reels which spin when a button is pushed. A slot machine usually includes a currency detector that validates the coin or money inserted to play. The machine pays off based on patterns of symbols visible on the front of the machine when it stops. Modern computer technology has resulted in many variations on the slot machine concept.

In Japanese search for a specific feature or features of a slot machine for purpose of validity / invalidity for patent litigation or licensing purpose, we recommend using F-theme, a unique Japanese patent classification system, and full text key words.

For example, we would use class of 2C082 which covers slot machines, card games, board games, etc. and overlaps with A63F1/00-5/04,531 in IPC classification system.

Under class 2C082, we would search for subclass AA00 (slot machine type) and DA00 (slot machine main body).

In full text search, we would use スロットマシン, or パチンコ or パチスロ as the Japanese synonyms of slot machine.
