This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in B26B (HAND-HELD CUTTING TOOLS NOT OTHERWISE PROVIDED FOR). As a US Corporation, Dryfhout Properties, Llc is one of the more focused assignees in the PatentsView dataset.

The composite Innovation Score of 22.7/100 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 5 grants, compared with 3 in the 2015–2019 window, a +67% 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. Dryfhout Properties, Llc's 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dryfhout Properties, Llc against peers pursuing similar technology classes.

How to use this portfolio
Dryfhout's 8 grants land it in the top 89% 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.
