Portfolio overview

Shanghai Easy-use Tools Enterprise Co., Ltd has been granted 21 US utility patents between 2015 and 2022, placing Shanghai Easy-use Tools Enterprise Co., Ltd at rank #14,249 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.2 claims per patent with primary concentration in B25B (TOOLS OR BENCH DEVICES NOT OTHERWISE PROVIDED FOR, FOR FASTENING, CONNECTING, DISENGAGING OR HOLDING). As a Foreign Corporation, Shanghai Easy-use Tools Enterprise Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between SCT Ltd. (21 patents, rank #14,245) and Shenzhen Ennoplus Technology Co., Ltd. (21 patents, rank #14,253) - the closest US assignees by grant volume. The composite Innovation Score of 36.9/100 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. Between 2020 and 2025 the company received 3 grants, compared with 18 in the 2015–2019 window, a -83% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Easy-use Tools Enterprise Co., Ltd's 6.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Easy-use Tools Enterprise Co., Ltd against peers pursuing similar technology classes.
