Key Points of the Japanese Patent System

Strict limitations on the timing and scope of amendments
Prohibition of "multi-multi" claims (multiple dependent claims referring to other multiple dependent claims)
High standards for written description and support requirements
Distinctive standards for assessing inventive step
Availability of accelerated examination
