Portfolio overview

Audio-technica Corporation has been granted 354 US utility patents between 2015 and 2025, placing Audio-technica Corporation at rank #1,196 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.8 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 Foreign Corporation, Audio-technica Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Audio-technica sits between Beijing Lenovo Software Ltd. (356 patents, rank #1,192) and AIR Products AND Chemicals, Inc. (353 patents, rank #1,200) - the closest US assignees by grant volume. The composite Innovation Score of 53.3/100 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 175 grants, compared with 179 in the 2015–2019 window, a -2% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Audio-technica Corporation's 5.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Audio-technica Corporation against peers pursuing similar technology classes.
