Portfolio overview

AVX Corporation has been granted 206 US utility patents between 2015 and 2024, placing AVX Corporation at rank #1,949 across all assignees tracked by PlainPatent. This portfolio spans 51 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.5 claims per patent with primary concentration in H01G (CAPACITORS; CAPACITORS, RECTIFIERS, DETECTORS, SWITCHING DEVICES, LIGHT-SENSITIVE OR TEMPERATURE-SENSITIVE DEVICES OF THE ELECTROLYTIC TYPE). As a US Corporation, AVX Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, AVX sits between TDK Electronics Ag (207 patents, rank #1,945) and Nissan Chemical Corporation (206 patents, rank #1,953) - the closest US assignees by grant volume. The composite Innovation Score of 56.4/100 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 85 grants, compared with 121 in the 2015–2019 window, a -30% 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. AVX Corporation's 21.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 51 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AVX 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.
