Portfolio overview

Huizhou University has been granted 22 US utility patents between 2015 and 2025, placing Huizhou University at #13,471 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 36 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.0 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Huizhou University is one of the more focused assignees in the PatentsView dataset. By volume, Huizhou sits between Hioki Denki Kabushiki Kaisha (22 patents, rank #13,455) and Harry's, Inc. (22 patents, rank #13,463) - the closest US assignees by grant volume. The composite Innovation Score of 50.7/100 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 16 grants, compared with 4 in the 2015–2019 window, a +300% 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. Huizhou University's 7.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 36 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
