USPTO PatentsView assignee record - 28 granted patents across 20 technology areas, active 2015–2019. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS).
The verdict
Opel holds 28 US patents across 20 technology areas, rank #11,033 of 50,000 tracked assignees.
Opel Solar, Inc. has been granted 28 US utility patents between 2015 and 2019, placing Opel Solar, Inc. at rank #11,033 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.7 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a US Corporation, Opel Solar, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Opel sits between OPKO Biologics Ltd. (28 patents, rank #11,029) and Phihong Technology Co., Ltd. (28 patents, rank #11,037) - the closest US assignees by grant volume. The composite Innovation Score of 38.0/100 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 28 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 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. Opel Solar, Inc.'s 17.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Opel Solar, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Opel's 28 grants land it in the top 42% 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.
