Portfolio overview
Brushtech, Inc. has been granted 12 US utility patents between 2015 and 2022, placing Brushtech, Inc. at rank #22,322 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.7 claims per patent with primary concentration in A46D (MANUFACTURE OF BRUSHES). As a US Corporation, Brushtech, Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 20.2/100 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 6 grants, compared with 6 in the 2015–2019 window — a +0% 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. Brushtech, Inc.'s 5.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Brushtech, Inc. against peers pursuing similar technology classes.
