Across all tracked assignees
USPTO PatentsView assignee record - 5 granted patents across 3 technology areas, active 2017–2020. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B25H (WORKSHOP EQUIPMENT, e.g. FOR MARKING-OUT WORK; STORAGE MEANS FOR WORKSHOPS).
The verdict
Heff holds 5 US patents across 3 technology areas, rank #47,485 of 50,000 tracked assignees.
Heff Industries Inc. has been granted 5 US utility patents between 2017 and 2020, placing Heff Industries Inc. at rank #47,485 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.0 claims per patent with primary concentration in B25H (WORKSHOP EQUIPMENT, e.g. FOR MARKING-OUT WORK; STORAGE MEANS FOR WORKSHOPS). As a US Corporation, Heff Industries Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Heff sits between Hebei Minmetals Co., Ltd. (5 patents, rank #47,481) and Helicoid Industries, Inc. (5 patents, rank #47,489) - the closest US assignees by grant volume. The composite Innovation Score of 13.5/100 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 2 grants, compared with 3 in the 2015–2019 window, a -33% 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. Heff Industries Inc.'s 2.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Heff Industries Inc. against peers pursuing similar technology classes.

How to use this portfolio
Heff's 5 grants land it in the top 98% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
