Portfolio overview

Shaanxi Normal University has been granted 14 US utility patents between 2016 and 2025, placing Shaanxi Normal University at rank #20,367 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.2 claims per patent with primary concentration in G03D (APPARATUS FOR PROCESSING EXPOSED PHOTOGRAPHIC MATERIALS ; ACCESSORIES THEREFOR). As a Foreign Corporation, Shaanxi Normal University is one of the more focused assignees in the PatentsView dataset. By volume, Shaanxi sits between Seoul Laser Dieboard System Co., Ltd. (14 patents, rank #20,363) and Shenzhen Cootway Technology Co., Ltd. (14 patents, rank #20,371) - 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 11 grants, compared with 3 in the 2015–2019 window, a +267% 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. Shaanxi Normal University's 7.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shaanxi Normal University against peers pursuing similar technology classes.
