Across all tracked assignees
USPTO PatentsView assignee record - 11 granted patents across 9 technology areas, active 2017–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING).
The verdict
Semco holds 11 US patents across 9 technology areas, rank #25,124 of 50,000 tracked assignees.
Semco Llc has been granted 11 US utility patents between 2017 and 2024, placing Semco Llc at rank #25,124 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.9 claims per patent with primary concentration in F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING). As a US Corporation, Semco Llc is one of the more focused assignees in the PatentsView dataset. By volume, Semco sits between Seiko PMC Corporation (11 patents, rank #25,120) and Shandong Computer Science Center (national Supercomputer Center IN Jinan) (11 patents, rank #25,128) - the closest US assignees by grant volume. The composite Innovation Score of 38.3/100 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 8 grants, compared with 3 in the 2015–2019 window, a +167% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Semco Llc's 22.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Semco Llc against peers pursuing similar technology classes.

How to use this portfolio
Semco's 11 grants land it in the top 41% 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.
