RINNAI CORPORATION

RINNAI CORPORATION has been granted 119 US utility patents between 2015 and 2025, placing RINNAI CORPORATION at rank #3,161 across all assignees tracked by PlainPatent. This portfolio spans 36 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.5 claims per patent with primary concentration in F24H (FLUID HEATERS, e.g. WATER OR AIR HEATERS, HAVING HEAT-GENERATING MEANS, e.g. HEAT PUMPS, IN GENERAL). As a Foreign Corporation, RINNAI CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.0/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 60 grants, compared with 59 in the 2015–2019 window — a +2% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. RINNAI CORPORATION's 4.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 36 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark RINNAI CORPORATION against peers pursuing similar technology classes.
