What this shows Zhejiang Topsun Logistic Control Co., Ltd. stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-DROP, BOOK-FULL. Volume places it #18,321 of 50,000; Innovation Score 31.8/100 sits in the top 61% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Aeris Gmbh (±0 grants).
Zhejiang Topsun Logistic Control Co., Ltd. has been granted 16 US utility patents between 2015 and 2025, placing Zhejiang Topsun Logistic Control Co., Ltd. at #18,321 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.3 claims per patent with primary concentration in B60P (VEHICLES ADAPTED FOR LOAD TRANSPORTATION OR TO TRANSPORT, TO CARRY, OR TO COMPRISE SPECIAL LOADS OR OBJECTS). As a Foreign Corporation, Zhejiang Topsun Logistic Control Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhejiang sits between ZS Pharma, Inc. (16 patents, rank #18,319) and Aeris Gmbh (16 patents, rank #18,327) - the closest US assignees by grant volume. The composite Innovation Score of 31.8/100 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. Between 2020 and 2024 the company received 4 grants, compared with 11 in the 2015–2019 window, a -64% 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. Zhejiang Topsun Logistic Control Co., Ltd.'s 12.3 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 17 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
