Portfolio overview
Doosan Enerbility Co., Ltd. has been granted 158 US utility patents between 2022 and 2025, placing Doosan Enerbility Co., Ltd. at rank #2,472 across all assignees tracked by PlainPatent. This portfolio spans 70 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.0 claims per patent with primary concentration in F05D (INDEXING SCHEME FOR ASPECTS RELATING TO NON-POSITIVE-DISPLACEMENT MACHINES OR ENGINES, GAS-TURBINES OR JET-PROPULSION PLANTS). As a Foreign Corporation, Doosan Enerbility Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 72.1/100 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 2022 through 2025, with 158 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. Doosan Enerbility Co., Ltd.'s 16.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 70 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Doosan Enerbility Co., Ltd. against peers pursuing similar technology classes.
