Portfolio overview

Dunan Sensing Llc has been granted 17 US utility patents between 2015 and 2020, placing Dunan Sensing Llc at rank #16,737 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.5 claims per patent with primary concentration in G01L (MEASURING FORCE, STRESS, TORQUE, WORK, MECHANICAL POWER, MECHANICAL EFFICIENCY, OR FLUID PRESSURE). As a US Corporation, Dunan Sensing Llc is one of the more focused assignees in the PatentsView dataset. By volume, Dunan sits between Downhole Products Limited (17 patents, rank #16,733) and Deepnorth Inc. (17 patents, rank #16,741) - the closest US assignees by grant volume. The composite Innovation Score of 33.3/100 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 1 grants, compared with 16 in the 2015–2019 window, a -94% 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. Dunan Sensing Llc's 18.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dunan Sensing Llc against peers pursuing similar technology classes.
