Portfolio overview

VAST Glory Electronics & Hardware & Plastic (hui Zhou) Ltd. has been granted 26 US utility patents between 2021 and 2025, placing VAST Glory Electronics & Hardware & Plastic (hui Zhou) Ltd. at #11,858 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in F28D (HEAT-EXCHANGE APPARATUS, NOT PROVIDED FOR IN ANOTHER SUBCLASS, IN WHICH THE HEAT-EXCHANGE MEDIA DO NOT COME INTO DIRECT CONTACT). As a Foreign Corporation, VAST Glory Electronics & Hardware & Plastic (hui Zhou) Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, VAST sits between Unarco Industries Llc (26 patents, rank #11,854) and Vyaire Medical Consumables Llc (26 patents, rank #11,862) - the closest US assignees by grant volume. The composite Innovation Score of 52.8/100 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 2021 through 2025, with 26 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. VAST Glory Electronics & Hardware & Plastic (hui Zhou) Ltd.'s 12.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 16 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
