How many patents does Zhejiang Sci-Tech University hold?

Zhejiang Sci-Tech University holds 24 US utility patents granted between 2016 and 2025, spanning 39 technology areas.

What is Zhejiang Sci-Tech University's Innovation Score?

Zhejiang Sci-Tech University has an Innovation Score of 57.8 out of 100 (top 5% of the corpus). This composite metric weighs portfolio volume (40%), grant velocity (20%), technology breadth (25%), and claim depth (15%).

Is Zhejiang Sci-Tech University's patent grant rate increasing or decreasing?

Zhejiang Sci-Tech University's recent grant velocity is +88% compared to the prior five-year period (grant years, not application filing dates). This indicates accelerating grant output.

What does claim depth mean for Zhejiang Sci-Tech University's patents?

Zhejiang Sci-Tech University's patents average 7.7 claims each. This is an aggregate descriptive count from the grant record; it does not establish claim scope, legal strength, enforceability, or design-around risk.

How is the Zhejiang Sci-Tech University patent data sourced?

All patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office covering US granted utility patents from 2015 to 2025.

Q: What technology areas does Zhejiang Sci-Tech University focus on?

Zhejiang Sci-Tech University's top technology area is G01B (Measuring Length, Thickness OR Similar Linear DIMENSIONS; Measuring ANGLES; Measuring AREAS; Measuring Irregularities OF Surfaces OR Contours) with 10 patents, ranking #141 of 2,030 assignees active in that subclass. Grants appear in 39 CPC subclasses total.

USPTO PatentsView assignee record - 24 granted patents across 39 technology areas, recorded in grant years 2016–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: G01B (Measuring Length, Thickness OR Similar Linear DIMENSIONS; Measuring ANGLES; Measuring AREAS; Measuring Irregularities OF Surfaces OR Contours).

What this shows Zhejiang's Innovation Score is 57.8/100 (top 5% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Zhejiang?

Each dot is one of Zhejiang’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Zhejiang’s own 7.7 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhejiang's grants concentrate

Zhejiang Sci-Tech University is a focused PatentsView assignee: 39 CPC subclasses with 41.7% of grants classified under G01B (Measuring Length, Thickness OR Similar Linear DIMENSIONS; Measuring ANGLES; Measuring AREAS; Measuring Irregularities OF Surfaces OR Contours). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2016. By volume, Zhejiang sits between Xactly Corporation and 1QB Information Technologies Inc..

Zhejiang's three-year grant acceleration

Zhejiang Sci-Tech University shows 12 grants in 2022–2024 against only 4 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
