Portfolio overview
Rinnai America Corporation has been granted 25 US utility patents between 2016 and 2024, placing Rinnai America Corporation at rank #12,195 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.5 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 US Corporation, Rinnai America Corporation is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 53.0/100 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 18 grants, compared with 7 in the 2015–2019 window — a +157% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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 America Corporation's 13.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rinnai America Corporation against peers pursuing similar technology classes.
