Portfolio overview

VOLTERRA SEMICONDUCTOR LLC has been granted 81 US utility patents between 2015 and 2024, placing VOLTERRA SEMICONDUCTOR LLC at rank #4,401 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.0 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a US Corporation, VOLTERRA SEMICONDUCTOR LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.2/100 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 6 grants, compared with 75 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. VOLTERRA SEMICONDUCTOR LLC's 20.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark VOLTERRA SEMICONDUCTOR LLC against peers pursuing similar technology classes.
