Portfolio overview

AECC Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd. has been granted 5 US utility patents between 2024 and 2025, placing AECC Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd. at rank #44,417 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in F01D (NON-POSITIVE DISPLACEMENT MACHINES OR ENGINES, e.g. STEAM TURBINES). As a Foreign Corporation, AECC Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, AECC sits between Advanced Systems AND Technologies, Inc. (5 patents, rank #44,413) and AEM Holdings Ltd. (5 patents, rank #44,421) - the closest US assignees by grant volume. The composite Innovation Score of 44.3/100 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. Historical data spans 2024 through 2025, with 5 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. AECC Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd.'s 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AECC Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd. against peers pursuing similar technology classes.
