Portfolio overview

Seagate Technology Llc has been granted 3,383 US utility patents between 2015 and 2025, placing Seagate Technology Llc at rank #107 across all assignees tracked by PlainPatent. This portfolio spans 169 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.5 claims per patent with primary concentration in G11B (INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER). As a US Corporation, Seagate Technology Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Seagate sits between Hamilton Sundstrand Corporation (hsc) (3,501 patents, rank #103) and Illinois TOOL Works Inc. (3,292 patents, rank #111) - the closest US assignees by grant volume. The composite Innovation Score of 67.8/100 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 1,133 grants, compared with 2,250 in the 2015–2019 window, a -50% 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. Seagate Technology Llc's 18.5 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 Seagate Technology Llc 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.
