Portfolio overview

Solarcity Corporation has been granted 217 US utility patents between 2015 and 2021, placing Solarcity Corporation at rank #1,858 across all assignees tracked by PlainPatent. This portfolio spans 70 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 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, Solarcity Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Solarcity sits between Huf Hülsbeck & Fürst Gmbh & Co. KG (217 patents, rank #1,854) and Egalax_empia Technology Inc. (216 patents, rank #1,862) - the closest US assignees by grant volume. The composite Innovation Score of 52.6/100 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 16 grants, compared with 201 in the 2015–2019 window, a -92% 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. Solarcity Corporation's 15.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 70 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Solarcity Corporation 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.
