Portfolio overview
BEIJING QIHOO TECHOLOGY COMPANY LIMITED has been granted 182 US utility patents between 2015 and 2021, placing BEIJING QIHOO TECHOLOGY COMPANY LIMITED at rank #2,163 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, BEIJING QIHOO TECHOLOGY COMPANY LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.9/100 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 4 grants, compared with 178 in the 2015–2019 window — a -98% 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. BEIJING QIHOO TECHOLOGY COMPANY LIMITED's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark BEIJING QIHOO TECHOLOGY COMPANY LIMITED against peers pursuing similar technology classes.
