Portfolio overview

Nostromo Ltd. has been granted 19 US utility patents between 2016 and 2025, placing Nostromo Ltd. at rank #15,503 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.2 claims per patent with primary concentration in F42B (EXPLOSIVE CHARGES, e.g. FOR BLASTING, FIREWORKS, AMMUNITION). As a Foreign Corporation, Nostromo Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nostromo sits between Ningbo Tolead International Business Co., Ltd. (19 patents, rank #15,499) and Nuflare Technology America, Inc. (19 patents, rank #15,507) - the closest US assignees by grant volume. The composite Innovation Score of 44.3/100 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 12 grants, compared with 7 in the 2015–2019 window, a +71% 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. Nostromo Ltd.'s 17.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nostromo Ltd. 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.
