Portfolio overview

EMC Corporation has been granted 1,455 US utility patents between 2015 and 2022, placing EMC Corporation at rank #292 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.3 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a US Corporation, EMC Corporation is one of the more focused assignees in the PatentsView dataset. By volume, EMC sits between Altria Client Services Llc (1,483 patents, rank #288) and JFE Steel Corporation (1,443 patents, rank #296) - the closest US assignees by grant volume. The composite Innovation Score of 57.3/100 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 15 grants, compared with 1,440 in the 2015–2019 window, a -99% 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. EMC Corporation's 19.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EMC Corporation 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.
