Portfolio overview

Japan Climate Systems Corporation has been granted 18 US utility patents between 2018 and 2024, placing Japan Climate Systems Corporation at #16,123 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.4 claims per patent with primary concentration in B60H (ARRANGEMENTS OF HEATING, COOLING, VENTILATING OR OTHER AIR-TREATING DEVICES SPECIALLY ADAPTED FOR PASSENGER OR GOODS SPACES OF VEHICLES). As a Foreign Corporation, Japan Climate Systems Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Japan sits between Iot And M2M Technologies, Llc (18 patents, rank #16,118) and JFE Chemical Corporation (18 patents, rank #16,126) - the closest US assignees by grant volume. The composite Innovation Score of 31.8/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 6 grants, compared with 12 in the 2015–2019 window, a -50% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Japan Climate Systems Corporation's 5.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 16 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
