USPTO PatentsView assignee record - 9 granted patents across 9 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02S (GENERATION OF ELECTRIC POWER BY CONVERSION OF INFRARED RADIATION, VISIBLE LIGHT OR ULTRAVIOLET LIGHT, e.g. USING PHOTOVOLTAIC [PV] MODULES).
The verdict
SUN holds 9 US patents across 9 technology areas, rank #30,108 of 50,000 tracked assignees.
SUN AND Steel Solar Llc has been granted 9 US utility patents between 2022 and 2025, placing SUN AND Steel Solar Llc at rank #30,108 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in H02S (GENERATION OF ELECTRIC POWER BY CONVERSION OF INFRARED RADIATION, VISIBLE LIGHT OR ULTRAVIOLET LIGHT, e.g. USING PHOTOVOLTAIC [PV] MODULES). As a US Corporation, SUN AND Steel Solar Llc is one of the more focused assignees in the PatentsView dataset. By volume, SUN sits between Stratec Consumables Gmbh (9 patents, rank #30,104) and Suntec Co., Ltd. (9 patents, rank #30,112) - the closest US assignees by grant volume. The composite Innovation Score of 48.6/100 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. Historical data spans 2022 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. SUN AND Steel Solar Llc's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SUN AND Steel Solar Llc against peers pursuing similar technology classes.

How to use this portfolio
SUN's 9 grants land it in the top 16% 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.
