Portfolio overview

Knowles Electronics, Llc has been granted 352 US utility patents between 2015 and 2025, placing Knowles Electronics, Llc at rank #1,203 across all assignees tracked by PlainPatent. This portfolio spans 53 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.6 claims per patent with primary concentration in H04R (LOUDSPEAKERS, MICROPHONES, GRAMOPHONE PICK-UPS OR LIKE ACOUSTIC ELECTROMECHANICAL TRANSDUCERS; DEAF-AID SETS; PUBLIC ADDRESS SYSTEMS). As a US Corporation, Knowles Electronics, Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Knowles sits between Hunter Douglas Inc. (354 patents, rank #1,199) and Dongwoo Fine-chem Co., Ltd. (351 patents, rank #1,207) - the closest US assignees by grant volume. The composite Innovation Score of 67.3/100 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 195 grants, compared with 157 in the 2015–2019 window, a +24% 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. Knowles Electronics, Llc's 19.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 53 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Knowles Electronics, Llc against peers pursuing similar technology classes.
