Portfolio overview
Shanghai Huali Microelectronics Corporation has been granted 120 US utility patents between 2015 and 2025, placing Shanghai Huali Microelectronics Corporation at rank #3,145 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Shanghai Huali Microelectronics Corporation is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 49.7/100 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 60 grants, compared with 60 in the 2015–2019 window — a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Microelectronics Corporation's 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Huali Microelectronics Corporation against peers pursuing similar technology classes.
