Portfolio overview

KRL Holding Company, Inc. has been granted 9 US utility patents between 2015 and 2025, placing KRL Holding Company, Inc. at rank #29,191 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.2 claims per patent with primary concentration in F41A (FUNCTIONAL FEATURES OR DETAILS COMMON TO BOTH SMALLARMS AND ORDNANCE, e.g. CANNONS; MOUNTINGS FOR SMALLARMS OR ORDNANCE). As a US Corporation, KRL Holding Company, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, KRL sits between Kosme S.r.l. Unipersonale (9 patents, rank #29,187) and Kurashiki KAKO Co., Ltd. (9 patents, rank #29,195) - the closest US assignees by grant volume. The composite Innovation Score of 30.8/100 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 3 grants, compared with 6 in the 2015–2019 window, a -50% 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. KRL Holding Company, Inc.'s 24.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KRL Holding Company, Inc. against peers pursuing similar technology classes.

How to use this portfolio

KRL's 9 grants land it in the top 64% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Most of this portfolio concentrates in F41A - see who else leads that technology area. F41A leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
