Portfolio overview

Dionex Corporation has been granted 105 US utility patents between 2015 and 2025, placing Dionex Corporation at rank #3,492 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a US Corporation, Dionex Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Dionex sits between VCE IP Holding Company Llc (106 patents, rank #3,488) and Guangzhou Automobile Group Co., Ltd. (105 patents, rank #3,496) - the closest US assignees by grant volume. The composite Innovation Score of 50.1/100 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 51 grants, compared with 54 in the 2015–2019 window, a -6% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Dionex Corporation's 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dionex Corporation 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.
