What this shows Shanghai Zhangmen Science AND Technology Co., Ltd. stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #16,347 of 50,000; Innovation Score 32.2/100 sits in the top 60% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Seegrid Corporation (±0 grants).
Shanghai Zhangmen Science AND Technology Co., Ltd. has been granted 18 US utility patents between 2019 and 2022, placing Shanghai Zhangmen Science AND Technology Co., Ltd. at #16,347 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.5 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a Foreign Corporation, Shanghai Zhangmen Science AND Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between Seegrid Corporation (18 patents, rank #16,330) and Shenzhen Lianda Technology Industrial Co., Ltd (18 patents, rank #16,338) - the closest US assignees by grant volume. The composite Innovation Score of 32.2/100 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 17 grants, compared with 1 in the 2015–2019 window, a +1600% 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. Shanghai Zhangmen Science AND Technology Co., Ltd.'s 12.5 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 10 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
