Portfolio overview

Ems-chemie Ag has been granted 11 US utility patents between 2015 and 2025, placing Ems-chemie Ag at rank #24,245 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.0 claims per patent with primary concentration in C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS). As a Foreign Corporation, Ems-chemie Ag is one of the more focused assignees in the PatentsView dataset. By volume, Ems-chemie sits between Election Systems & Software, Llc (11 patents, rank #24,241) and EOS Of North America, Inc. (11 patents, rank #24,249) - the closest US assignees by grant volume. The composite Innovation Score of 51.8/100 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 9 grants, compared with 2 in the 2015–2019 window, a +350% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Ems-chemie Ag's 20.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ems-chemie Ag against peers pursuing similar technology classes.

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.
