USPTO PatentsView assignee record - 6 granted patents across 13 technology areas, active 2023–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS).
The verdict
CPK holds 6 US patents across 13 technology areas, rank #39,443 of 50,000 tracked assignees.
CPK Interior Products Inc. has been granted 6 US utility patents between 2023 and 2025, placing CPK Interior Products Inc. at rank #39,443 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 33.3 claims per patent with primary concentration in C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS). As a Foreign Corporation, CPK Interior Products Inc. is one of the more focused assignees in the PatentsView dataset. By volume, CPK sits between Corvent Medical, Inc. (6 patents, rank #39,439) and CPT Zwei Gmbh (6 patents, rank #39,447) - the closest US assignees by grant volume. The composite Innovation Score of 54.5/100 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 2023 through 2025, with 6 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. CPK Interior Products Inc.'s 33.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CPK Interior Products Inc. against peers pursuing similar technology classes.

How to use this portfolio
CPK's 6 grants land it in the top 8% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
