Volume places it #17,718 of 50,000; Innovation Score 49.0/100 sits in the top 15% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Gozney Group Limited (±0 grants).
Greenheck Fan Corporation has been granted 16 US utility patents between 2016 and 2025, placing Greenheck Fan Corporation at #17,718 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 claims per patent with primary concentration in F04D (NON-POSITIVE-DISPLACEMENT PUMPS). As a US Corporation, Greenheck Fan Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Greenheck sits between Gozney Group Limited (16 patents, rank #17,715) and Gunitech Corp. (16 patents, rank #17,723) - the closest US assignees by grant volume. The composite Innovation Score of 49.0/100 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 7 grants, compared with 8 in the 2015–2019 window, a -12% 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 US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Greenheck Fan Corporation's 18.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 18 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
