Portfolio overview

Huizhou Happy Vaping Technology Limited has been granted 25 US utility patents between 2022 and 2025, placing Huizhou Happy Vaping Technology Limited at #12,046 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in A24F (SMOKERS' REQUISITES; MATCH BOXES; SIMULATED SMOKING DEVICES). As a Foreign Corporation, Huizhou Happy Vaping Technology Limited is one of the more focused assignees in the PatentsView dataset. By volume, Huizhou sits between Helmut Fischer Gmbh Institut Für Elektronik UND Messtechnik (25 patents, rank #12,031) and Head Technology Gmbh (25 patents, rank #12,039) - the closest US assignees by grant volume. The composite Innovation Score of 50.1/100 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 2022 through 2025, with 25 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. Huizhou Happy Vaping Technology Limited's 6.5 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.
