Portfolio overview

AAC Technologies Pte. Ltd. has been granted 946 US utility patents between 2015 and 2025, placing AAC Technologies Pte. Ltd. at rank #467 across all assignees tracked by PlainPatent. This portfolio spans 73 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 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 Technologies Pte. Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, AAC sits between Marvell World Trade Ltd. (967 patents, rank #463) and Uber Technologies, Inc. (941 patents, rank #471) - the closest US assignees by grant volume. The composite Innovation Score of 55.8/100 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 438 grants, compared with 508 in the 2015–2019 window, a -14% 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. AAC Technologies Pte. Ltd.'s 10.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 73 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AAC Technologies Pte. Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
