Portfolio overview

Hebei University OF Science AND Technology has been granted 9 US utility patents between 2016 and 2025, placing Hebei University OF Science AND Technology at rank #28,925 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in B01L (CHEMICAL OR PHYSICAL LABORATORY APPARATUS FOR GENERAL USE). As a Foreign Corporation, Hebei University OF Science AND Technology is one of the more focused assignees in the PatentsView dataset. By volume, Hebei sits between HD Microsystems, Ltd. (9 patents, rank #28,921) and Hengdian Group Innuovo Electric Co., Ltd. (9 patents, rank #28,929) - the closest US assignees by grant volume. The composite Innovation Score of 34.8/100 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. Between 2020 and 2025 the company received 6 grants, compared with 3 in the 2015–2019 window, a +100% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Hebei University OF Science AND Technology's 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hebei University OF Science AND Technology 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.
