Portfolio overview
AAC Optics (Changzhou) Co., Ltd. has been granted 58 US utility patents between 2020 and 2025, placing AAC Optics (Changzhou) Co., Ltd. at rank #5,812 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, AAC Optics (Changzhou) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.9/100 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. Historical data spans 2020 through 2025, with 58 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Optics (Changzhou) Co., Ltd.'s 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AAC Optics (Changzhou) Co., Ltd. against peers pursuing similar technology classes.
