Portfolio overview

Hengdian Group Dmegc Magnetics Co., Ltd has been granted 7 US utility patents between 2024 and 2025, placing Hengdian Group Dmegc Magnetics Co., Ltd at rank #35,632 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.9 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Hengdian Group Dmegc Magnetics Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Hengdian sits between Helix Co., Ltd. (7 patents, rank #35,628) and Hexagon Manufacturing Intelligence SARL (7 patents, rank #35,636) - the closest US assignees by grant volume. The composite Innovation Score of 49.9/100 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 2024 through 2025, with 7 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. Hengdian Group Dmegc Magnetics Co., Ltd's 15.9 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 Hengdian Group Dmegc Magnetics Co., Ltd against peers pursuing similar technology classes.
