Portfolio overview

SMA Solar Technology Ag has been granted 231 US utility patents between 2015 and 2025, placing SMA Solar Technology Ag at rank #1,763 across all assignees tracked by PlainPatent. This portfolio spans 44 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, SMA Solar Technology Ag is one of the more focused assignees in the PatentsView dataset. By volume, SMA sits between JUUL Labs, Inc. (231 patents, rank #1,759) and Autel Intelligent Technology Corp., Ltd. (230 patents, rank #1,767) - the closest US assignees by grant volume. The composite Innovation Score of 58.6/100 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. Between 2020 and 2025 the company received 99 grants, compared with 132 in the 2015–2019 window, a -25% 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. SMA Solar Technology Ag's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 44 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SMA Solar Technology Ag 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.
