Portfolio overview

Woori FINE CHEM Co., Ltd. has been granted 11 US utility patents between 2022 and 2024, placing Woori FINE CHEM Co., Ltd. at rank #25,524 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in C07C (ACYCLIC OR CARBOCYCLIC COMPOUNDS). As a Foreign Corporation, Woori FINE CHEM Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Woori sits between Wilton Industries, Inc. (11 patents, rank #25,520) and Wagner Group Gmbh (11 patents, rank #25,528) - the closest US assignees by grant volume. The composite Innovation Score of 43.1/100 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 2024, with 11 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. Woori FINE CHEM Co., Ltd.'s 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Woori FINE CHEM Co., Ltd. against peers pursuing similar technology classes.
