Portfolio overview

Zhigu Holdings Limited has been granted 7 US utility patents between 2016 and 2018, placing Zhigu Holdings Limited at rank #38,433 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, Zhigu Holdings Limited is one of the more focused assignees in the PatentsView dataset. By volume, Zhigu sits between Zhejiang Jihengkang (jhk) Door Industry Co., Ltd (7 patents, rank #38,429) and Zhuhai Chuangfeixin Technology Co., Ltd. (7 patents, rank #38,437) - the closest US assignees by grant volume. The composite Innovation Score of 25.0/100 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 0 grants, compared with 7 in the 2015–2019 window, a -100% 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. Zhigu Holdings Limited's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhigu Holdings Limited against peers pursuing similar technology classes.
