Portfolio overview

National DONG HWA University has been granted 11 US utility patents between 2015 and 2024, placing National DONG HWA University at rank #24,832 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, National DONG HWA University is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Nanhua Intelligent Precision Machine (shenzhen) Co., Ltd. (11 patents, rank #24,828) and Native Instruments Gmbh (11 patents, rank #24,836) - the closest US assignees by grant volume. The composite Innovation Score of 46.9/100 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 3 grants, compared with 8 in the 2015–2019 window, a -62% 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 DONG HWA University's 10.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National DONG HWA University against peers pursuing similar technology classes.

How to use this portfolio

National's 11 grants land it in the top 20% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - National ranks #24,832 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A61K - see who else leads that technology area. A61K leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
