USPTO PatentsView assignee record - 10 granted patents across 1 technology areas, active 2015–2018. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS).
The verdict
AO holds 10 US patents across 1 technology areas, rank #25,691 of 50,000 tracked assignees.
AO Ether Corporation has been granted 10 US utility patents between 2015 and 2018, placing AO Ether Corporation at rank #25,691 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, AO Ether Corporation is one of the more focused assignees in the PatentsView dataset. By volume, AO sits between Annovi Reverberi S.p.a. (10 patents, rank #25,687) and APHP (assistance Publique Hôpitaux DE Paris) (10 patents, rank #25,695) - the closest US assignees by grant volume. The composite Innovation Score of 20.5/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% 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. AO Ether Corporation's 14.5 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 AO Ether Corporation against peers pursuing similar technology classes.

How to use this portfolio
AO's 10 grants land it in the top 93% 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.
