Portfolio overview
Western Digital Technologies, Inc. has been granted 3,986 US utility patents between 2015 and 2025, placing Western Digital Technologies, Inc. at rank #89 across all assignees tracked by PlainPatent. This portfolio spans 144 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.5 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a US Corporation, Western Digital Technologies, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 72.0/100 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 2,518 grants, compared with 1,468 in the 2015–2019 window — a +72% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 Technologies, Inc.'s 19.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Western Digital Technologies, Inc. against peers pursuing similar technology classes.
