Portfolio overview

National Chung Cheng University has been granted 156 US utility patents between 2015 and 2025, placing National Chung Cheng University at rank #2,504 across all assignees tracked by PlainPatent. This portfolio spans 129 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 claims per patent with primary concentration in G06T (IMAGE DATA PROCESSING OR GENERATION, IN GENERAL). As a Foreign Corporation, National Chung Cheng University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, National sits between Cyberark Software Ltd. (156 patents, rank #2,500) and Zhejiang Jinko Solar Co., Ltd. (156 patents, rank #2,508) - the closest US assignees by grant volume. The composite Innovation Score of 55.9/100 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 74 grants, compared with 82 in the 2015–2019 window, a -10% 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 Chung Cheng University's 10.7 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 Chung Cheng University 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.
