The verdict
Haldor holds 275 US patents across 74 technology areas, rank #1,507 of 50,000 tracked assignees.
Haldor Topsøe A/s has been granted 275 US utility patents between 2015 and 2025, placing Haldor Topsøe A/s at rank #1,507 across all assignees tracked by PlainPatent. This portfolio spans 74 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, Haldor Topsøe A/s is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Haldor sits between Ringcentral, Inc. (277 patents, rank #1,503) and Unist(ulsan National Institute OF Science AND Technology) (275 patents, rank #1,511) - the closest US assignees by grant volume. The composite Innovation Score of 56.0/100 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 153 grants, compared with 122 in the 2015–2019 window, a +25% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Haldor Topsøe A/s's 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 74 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Haldor Topsøe A/s against peers pursuing similar technology classes.

How to use this portfolio
Haldor's 275 grants land it in the top 6% 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.
