What this shows Zhejiang University City College stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-PAR, CLAIMS-SPARSE, TYPE-FRNCORP, SPAN-YRS, BOOK-RICH. Volume places it #16,531 of 50,000; Innovation Score 53.0/100 sits in the top 9% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Biomérieux, S.a. (±0 grants).
Zhejiang University City College has been granted 18 US utility patents between 2022 and 2025, placing Zhejiang University City College at #16,531 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in E02D (FOUNDATIONS; EXCAVATIONS; EMBANKMENTS ; UNDERGROUND OR UNDERWATER STRUCTURES). As a Foreign Corporation, Zhejiang University City College is one of the more focused assignees in the PatentsView dataset. By volume, Zhejiang sits between Zhejiang Twinsel Electronic Technology Co., Ltd. (18 patents, rank #16,526) and Iposi, Inc. (18 patents, rank #16,534) - the closest US assignees by grant volume. The composite Innovation Score of 53.0/100 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 18 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. Zhejiang University City College's 6.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 28 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
