Portfolio overview

Shanghai Highly Electrical Appliances Co., Ltd. has been granted 6 US utility patents between 2021 and 2024, placing Shanghai Highly Electrical Appliances Co., Ltd. at rank #42,816 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS). As a Foreign Corporation, Shanghai Highly Electrical Appliances Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between Shang HAI PAN SHI TOU ZI GUAN LI YOU XIAN GONG SI (6 patents, rank #42,812) and Shanghai Microport EP Medtech Co., Ltd. (6 patents, rank #42,820) - the closest US assignees by grant volume. The composite Innovation Score of 45.8/100 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. Historical data spans 2021 through 2024, with 6 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 Highly Electrical Appliances Co., Ltd.'s 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Highly Electrical Appliances Co., Ltd. against peers pursuing similar technology classes.
