Portfolio overview

Haohong Electric Technology (hubei) Co., Ltd. has been granted 19 US utility patents between 2023 and 2025, placing Haohong Electric Technology (hubei) Co., Ltd. at #15,332 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.8 claims per patent with primary concentration in F24C (DOMESTIC STOVES OR RANGES  ; DETAILS OF DOMESTIC STOVES OR RANGES, OF GENERAL APPLICATION). As a Foreign Corporation, Haohong Electric Technology (hubei) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Haohong sits between Hytorc Division UNEX Corporation (19 patents, rank #15,345) and Honeywell Asca (19 patents, rank #15,353) - the closest US assignees by grant volume. The composite Innovation Score of 40.1/100 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. Historical data spans 2023 through 2025, with 19 total grants over that period. 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. Haohong Electric Technology (hubei) Co., Ltd.'s 1.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 6 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
