Portfolio overview

Hoshizaki America, Inc. has been granted 15 US utility patents between 2015 and 2025, placing Hoshizaki America, Inc. at rank #18,733 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.3 claims per patent with primary concentration in F25C (PRODUCING, WORKING OR HANDLING ICE). As a US Corporation, Hoshizaki America, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Hoshizaki sits between Homax Products, Inc. (15 patents, rank #18,729) and Hubbardton Forge, Llc. (15 patents, rank #18,737) - the closest US assignees by grant volume. The composite Innovation Score of 45.0/100 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 7 grants, compared with 8 in the 2015–2019 window, a -12% 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. Hoshizaki America, Inc.'s 17.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hoshizaki America, 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.
