High-Performance storage patents: who holds the ground and where claim space is still open
79.6% concentration. The top five assignees alone account for 1,807 of the 2,269 records in scope — a field with one dominant filer and a long tail behind it. Filings rose from 100 in 2017 to a peak of 341 in 2022. The 2021-to-2024 comparison — 294 down to 257 — is a 13% pullback over three years, the most recent span that is not distorted by publication lag. Years after 2024 should be read as undercounted, not as evidence of a further decline.

Common questions about high-performance storage patents
Who holds the most patents in high-performance storage?
One assignee leads clearly, with 1,520 of the 2,269 records in scope, and the top five assignees combined hold 79.6% of all records. That level of concentration means most freedom-to-operate questions in this field come down to checking against a small number of large portfolios rather than a broad competitive set. The ranking used here covers the 100 companies the dataset returns, not an arbitrary top-10 or top-50 cut.
Is patent filing in high-performance storage growing or slowing?
Filing rose from 100 records in 2017 to a peak of 341 in 2022, then eased to 257 by 2024, a 13% decline over that three-year span. That is the last period that can be read reliably, since publication typically lags filing by around 18 months and the 2025-2026 figures are still incomplete. On the evidence available, this looks like a maturing filing cohort rather than a sharp downturn.
What technology areas do high-performance storage patents cover?
The large majority, 91.7% of the 2,269 records, carry a G06F classification for electric digital data processing, with digital information transmission (H04L) present in 22.0% of records. Memory-specific classes such as G11C (static and digital memories, 3.1%) and G11B (magnetic and optical storage, 0.6%) are comparatively small, indicating most claims are framed at the system or software level rather than the physical memory layer. Because a single record can carry multiple IPC codes, these shares add up to more than 100% of the record total and should not be summed.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on High-Performance Storage Patent Landscape covering 2015–2026, data cut-off 2026-08-31.
