Portfolio overview

Kingsand Machinery Ltd. has been granted 10 US utility patents between 2015 and 2021, placing Kingsand Machinery Ltd. at rank #26,662 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.2 claims per patent with primary concentration in B27C (PLANING, DRILLING, MILLING, TURNING OR UNIVERSAL MACHINES FOR WOOD OR SIMILAR MATERIAL). As a Foreign Corporation, Kingsand Machinery Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kingsand sits between Kidde FIRE Protection, Llc (10 patents, rank #26,658) and KMEW Co., Ltd. (10 patents, rank #26,666) - the closest US assignees by grant volume. The composite Innovation Score of 23.2/100 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 1 grants, compared with 9 in the 2015–2019 window, a -89% 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. Kingsand Machinery Ltd.'s 6.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kingsand Machinery 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.
