Portfolio overview

Shanghai Huali Integrated Circuit Mfg. Co., Ltd. has been granted 14 US utility patents between 2021 and 2023, placing Shanghai Huali Integrated Circuit Mfg. Co., Ltd. at rank #20,435 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Shanghai Huali Integrated Circuit Mfg. Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.2/100 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 2021 through 2023, with 14 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. Shanghai Huali Integrated Circuit Mfg. Co., Ltd.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Huali Integrated Circuit Mfg. Co., Ltd. against peers pursuing similar technology classes.
