The verdict
Nautilus holds 5 US patents across 8 technology areas, rank #48,972 of 50,000 tracked assignees.
Nautilus Capital Corporation has been granted 5 US utility patents between 2016 and 2019, placing Nautilus Capital Corporation at rank #48,972 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 32.6 claims per patent with primary concentration in C01B (NON-METALLIC ELEMENTS; COMPOUNDS THEREOF; ; METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C). As a US Corporation, Nautilus Capital Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Nautilus sits between National University Corporation (5 patents, rank #48,968) and Nctech Ltd (5 patents, rank #48,976) - the closest US assignees by grant volume. The composite Innovation Score of 31.2/100 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 0 grants, compared with 5 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Nautilus Capital Corporation's 32.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nautilus Capital Corporation against peers pursuing similar technology classes.

How to use this portfolio
Nautilus's 5 grants land it in the top 63% 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.
