Portfolio overview
National Taiwan Normal University has been granted 115 US utility patents between 2015 and 2025, placing National Taiwan Normal University at rank #3,261 across all assignees tracked by PlainPatent. This portfolio spans 118 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, National Taiwan Normal University is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 50.5/100 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 53 grants, compared with 62 in the 2015–2019 window — a -15% 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. National Taiwan Normal University's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Taiwan Normal University against peers pursuing similar technology classes.
