The verdict
Unist(ulsan holds 275 US patents across 138 technology areas, rank #1,511 of 50,000 tracked assignees.
Unist(ulsan National Institute OF Science AND Technology) has been granted 275 US utility patents between 2016 and 2025, placing Unist(ulsan National Institute OF Science AND Technology) at rank #1,511 across all assignees tracked by PlainPatent. This portfolio spans 138 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Unist(ulsan National Institute OF Science AND Technology) is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Unist(ulsan sits between Haldor Topsøe A/s (275 patents, rank #1,507) and Cambria Company Llc (274 patents, rank #1,515) - the closest US assignees by grant volume. The composite Innovation Score of 61.0/100 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 211 grants, compared with 64 in the 2015–2019 window, a +230% 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. Unist(ulsan National Institute OF Science AND Technology)'s 11.7 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 Unist(ulsan National Institute OF Science AND Technology) against peers pursuing similar technology classes.

How to use this portfolio
Unist(ulsan's 275 grants land it in the top 3% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
