Portfolio overview

SanDisk 3D LLC has been granted 112 US utility patents between 2015 and 2017, placing SanDisk 3D LLC at rank #3,333 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.5 claims per patent with primary concentration in H10B (ELECTRONIC MEMORY DEVICES). As a US Corporation, SanDisk 3D LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.8/100 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 0 grants, compared with 112 in the 2015–2019 window — a -100% 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. SanDisk 3D LLC's 19.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SanDisk 3D LLC against peers pursuing similar technology classes.
