Portfolio overview

HCT Asia Limited has been granted 21 US utility patents between 2015 and 2021, placing HCT Asia Limited at #14,029 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.0 claims per patent with primary concentration in A45D (HAIRDRESSING OR SHAVING EQUIPMENT ; EQUIPMENT FOR COSMETICS OR COSMETIC TREATMENTS, e.g. FOR MANICURING OR PEDICURING). As a Foreign Corporation, HCT Asia Limited is one of the more focused assignees in the PatentsView dataset. By volume, HCT sits between Greenlight Biosciences, Inc. (21 patents, rank #14,021) and Heriot-watt University (21 patents, rank #14,029) - the closest US assignees by grant volume. The composite Innovation Score of 34.1/100 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. Between 2020 and 2024 the company received 2 grants, compared with 19 in the 2015–2019 window, a -89% 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. HCT Asia Limited's 17.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 14 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
