Portfolio overview

E8 Storage Systems Ltd. has been granted 11 US utility patents between 2015 and 2019, placing E8 Storage Systems Ltd. at rank #24,230 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.4 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, E8 Storage Systems Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, E8 sits between Dynasthetics, Llc (11 patents, rank #24,226) and Ecoflow Inc. (11 patents, rank #24,234) - the closest US assignees by grant volume. The composite Innovation Score of 24.7/100 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 11 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 Foreign 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. E8 Storage Systems Ltd.'s 18.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark E8 Storage Systems Ltd. against peers pursuing similar technology classes.

How to use this portfolio

E8's 11 grants land it in the top 85% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - E8 ranks #24,230 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G06F - see who else leads that technology area. G06F leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
