SUNPOWER CORPORATION

SUNPOWER CORPORATION has been granted 601 US utility patents between 2015 and 2024, placing SUNPOWER CORPORATION at rank #764 across all assignees tracked by PlainPatent. This portfolio spans 96 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, SUNPOWER CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 59.8/100 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 215 grants, compared with 386 in the 2015–2019 window — a -44% 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. SUNPOWER CORPORATION's 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 96 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SUNPOWER CORPORATION against peers pursuing similar technology classes.
