The verdict
Chemex holds 7 US patents across 1 technology areas, rank #34,670 of 50,000 tracked assignees.
Chemex Foundry Solutions Gmbh has been granted 7 US utility patents between 2020 and 2025, placing Chemex Foundry Solutions Gmbh at rank #34,670 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.0 claims per patent with primary concentration in B22C (FOUNDRY MOULDING). As a Foreign Corporation, Chemex Foundry Solutions Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Chemex sits between Chase Therapeutics Corporation (7 patents, rank #34,666) and China Industries Limited (7 patents, rank #34,674) - the closest US assignees by grant volume. The composite Innovation Score of 28.2/100 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 2020 through 2025, with 7 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. Chemex Foundry Solutions Gmbh's 18.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chemex Foundry Solutions Gmbh against peers pursuing similar technology classes.

How to use this portfolio
Chemex's 7 grants land it in the top 74% 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.
