Portfolio overview

Henrob Limited has been granted 14 US utility patents between 2015 and 2018, placing Henrob Limited at rank #19,868 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.7 claims per patent with primary concentration in B21J (FORGING; HAMMERING; PRESSING METAL; RIVETING; FORGE FURNACES). As a Foreign Corporation, Henrob Limited is one of the more focused assignees in the PatentsView dataset. By volume, Henrob sits between Heartbeam, Inc. (14 patents, rank #19,864) and Hong Kong R&D Centre For Logistics And Supply Chain Management Enabling Technologies Limited (14 patents, rank #19,872) - the closest US assignees by grant volume. The composite Innovation Score of 36.4/100 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 14 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 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. Henrob Limited's 24.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Henrob Limited 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.
