Portfolio overview

Dongbu Daewoo Electronics Corporation has been granted 169 US utility patents between 2015 and 2022, placing Dongbu Daewoo Electronics Corporation at rank #2,311 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in D06F (LAUNDERING, DRYING, IRONING, PRESSING OR FOLDING TEXTILE ARTICLES). As a Foreign Corporation, Dongbu Daewoo Electronics Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Dongbu sits between Agfa Nv (169 patents, rank #2,307) and IDAC Holdings, Inc. (169 patents, rank #2,315) - the closest US assignees by grant volume. The composite Innovation Score of 49.6/100 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 7 grants, compared with 162 in the 2015–2019 window, a -96% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Dongbu Daewoo Electronics Corporation's 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dongbu Daewoo Electronics Corporation against peers pursuing similar technology classes.
