Portfolio overview

KOK & VAN Engelen Composite Structures B.v. has been granted 5 US utility patents between 2022 and 2024, placing KOK & VAN Engelen Composite Structures B.v. at rank #48,131 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 claims per patent with primary concentration in B29C (SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING). As a Foreign Corporation, KOK & VAN Engelen Composite Structures B.v. is one of the more focused assignees in the PatentsView dataset. By volume, KOK sits between Koatsu Co., Ltd. (5 patents, rank #48,127) and Koros Technology (shenzhen) Co. Ltd (5 patents, rank #48,135) - the closest US assignees by grant volume. The composite Innovation Score of 46.4/100 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 5 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. KOK & VAN Engelen Composite Structures B.v.'s 13.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KOK & VAN Engelen Composite Structures B.v. against peers pursuing similar technology classes.
