Portfolio overview

Yunnan Huapu Quantum Material Co., Ltd has been granted 10 US utility patents between 2023 and 2025, placing Yunnan Huapu Quantum Material Co., Ltd at rank #27,861 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Yunnan Huapu Quantum Material Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Yunnan sits between Yonex Co., Ltd. (10 patents, rank #27,857) and Yiwu Ledou Pet Products Co., Ltd. (10 patents, rank #27,865) - the closest US assignees by grant volume. The composite Innovation Score of 49.8/100 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 2023 through 2025, with 10 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. Yunnan Huapu Quantum Material Co., Ltd's 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yunnan Huapu Quantum Material Co., Ltd against peers pursuing similar technology classes.

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.
