USPTO PatentsView assignee record — 58 granted patents across 42 technology areas, active 2016–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G08B (SIGNALLING OR CALLING SYSTEMS; ORDER TELEGRAPHS; ALARM SYSTEMS).
The verdict
Nortek holds 58 US patents across 42 technology areas — rank #5,864 of 50,000 tracked assignees.
NORTEK SECURITY & CONTROL has been granted 58 US utility patents between 2016 and 2024, placing NORTEK SECURITY & CONTROL at rank #5,864 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.6 claims per patent with primary concentration in G08B (SIGNALLING OR CALLING SYSTEMS; ORDER TELEGRAPHS; ALARM SYSTEMS). As a US Corporation, NORTEK SECURITY & CONTROL is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 53.0/100 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 31 grants, compared with 27 in the 2015–2019 window — a +15% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. NORTEK SECURITY & CONTROL's 17.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NORTEK SECURITY & CONTROL against peers pursuing similar technology classes.

How to use this portfolio
Nortek's 58 grants land it in the top 9% 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.
