Portfolio overview
LeafFilter North, LLC has been granted 48 US utility patents between 2019 and 2025, placing LeafFilter North, LLC at rank #6,915 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.6 claims per patent with primary concentration in E04D (ROOF COVERINGS; SKY-LIGHTS; GUTTERS; ROOF-WORKING TOOLS). As a US Corporation, LeafFilter North, LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 25.5/100 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 41 grants, compared with 7 in the 2015–2019 window — a +486% 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. LeafFilter North, LLC's 9.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LeafFilter North, LLC against peers pursuing similar technology classes.
