Portfolio overview

Western Digital (fremont), Llc has been granted 227 US utility patents between 2015 and 2019, placing Western Digital (fremont), Llc at rank #1,801 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in G11B (INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER). As a US Corporation, Western Digital (fremont), Llc is one of the more focused assignees in the PatentsView dataset. By volume, Western sits between Modernatx, Inc. (227 patents, rank #1,797) and SK Planet Co., Ltd. (226 patents, rank #1,805) - the closest US assignees by grant volume. The composite Innovation Score of 49.6/100 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 0 grants, compared with 227 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. Western Digital (fremont), Llc's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Western Digital (fremont), Llc against peers pursuing similar technology classes.
