Portfolio overview

Ferno-washington, Inc. has been granted 74 US utility patents between 2015 and 2024, placing Ferno-washington, Inc. at rank #4,714 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in A61G (TRANSPORT, PERSONAL CONVEYANCES, OR ACCOMMODATION SPECIALLY ADAPTED FOR PATIENTS OR DISABLED PERSONS ; OPERATING TABLES OR CHAIRS; CHAIRS FOR DENTISTRY; FUNERAL DEVICES). As a US Corporation, Ferno-washington, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Ferno-washington sits between EOS Products, Llc (74 patents, rank #4,710) and Hefei Hualing Co., Ltd. (74 patents, rank #4,718) - the closest US assignees by grant volume. The composite Innovation Score of 42.9/100 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 22 grants, compared with 52 in the 2015–2019 window, a -58% 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. Ferno-washington, Inc.'s 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ferno-washington, Inc. 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.
