Overall rank by patents
#43,155
Across all tracked assignees
USPTO PatentsView assignee record - 6 granted patents across 4 technology areas, active 2024–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION).
The verdict
Shanghai holds 6 US patents across 4 technology areas, rank #43,155 of 50,000 tracked assignees.
Shanghai Nanojclean Technology Co., Ltd. has been granted 6 US utility patents between 2024 and 2025, placing Shanghai Nanojclean Technology Co., Ltd. at rank #43,155 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a Foreign Corporation, Shanghai Nanojclean Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between Shanghai Aucta Pharmaceuticals Co., Ltd. (6 patents, rank #43,151) and Shanghai Wangmengzhu Pet Products Co., Ltd. (6 patents, rank #43,159) - the closest US assignees by grant volume. The composite Innovation Score of 42.4/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Historical data spans 2024 through 2025, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Shanghai Nanojclean Technology Co., Ltd.'s 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Nanojclean Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shanghai's 6 grants land it in the top 31% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
