Portfolio overview

AAC Acoustic Technologies (shenzhen) Co., Ltd. has been granted 257 US utility patents between 2015 and 2025, placing AAC Acoustic Technologies (shenzhen) Co., Ltd. at rank #1,606 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 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, AAC Acoustic Technologies (shenzhen) Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, AAC sits between GE Healthcare Bio-science AB (258 patents, rank #1,602) and Asahi Kasei Microdevices Corporation (256 patents, rank #1,610) - the closest US assignees by grant volume. The composite Innovation Score of 55.4/100 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 170 grants, compared with 87 in the 2015–2019 window, a +95% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. AAC Acoustic Technologies (shenzhen) Co., Ltd.'s 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 50 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AAC Acoustic Technologies (shenzhen) Co., Ltd. against peers pursuing similar technology classes.
