Portfolio overview

Eppendorf Ag has been granted 97 US utility patents between 2015 and 2025, placing Eppendorf Ag at rank #3,732 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in B01L (CHEMICAL OR PHYSICAL LABORATORY APPARATUS FOR GENERAL USE). As a Foreign Corporation, Eppendorf Ag is one of the more focused assignees in the PatentsView dataset. By volume, Eppendorf sits between Carefusion 2200, Inc. (97 patents, rank #3,728) and Korea Institute Of Ocean Science & Technology (97 patents, rank #3,736) - the closest US assignees by grant volume. The composite Innovation Score of 53.6/100 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 32 grants, compared with 65 in the 2015–2019 window, a -51% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Eppendorf Ag's 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Eppendorf 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.
