Logic & Memory Devices Patents: Who Leads, Where the Gaps Are 2026
Logic and memory device patents: who holds the ground and where it is still open
36.9% concentration. The top five assignees alone account for 135,283 of the 366,872 records in scope — filing here means crossing occupied claim space, not empty ground. Volume rose from 699 in 2017 to a peak of 1,061 in 2020, then fell 32% from 1,003 in 2021 to 686 in 2024 — the most recent year that can be treated as complete, since publication lags filing by roughly 18 months and 2025-2026 figures will still fill in.

Common questions about the logic and memory device patent landscape
Who holds the most logic and memory device patents?
One assignee leads with 44,464 records, a scale well beyond fifth place at 12,766 and tenth at 5,495 records in the ranking. The top five assignees combine for 135,283 records, 36.9% of the 366,872 records in scope, and the top ten reach 47.5%. That leaves a long tail of smaller filers below a clearly dominant handful, so competitive analysis in this field should focus first on the leader’s family claims rather than assume an evenly spread market.
Is filing activity in logic and memory devices growing or slowing?
Filings peaked at 1,061 in 2020 and have since fallen 32%, from 1,003 in 2021 to 686 in 2024, the last year that can be treated as complete. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures are still filling in and should not be read as evidence of a further drop. The honest read is a cooling from a 2020 high, not a collapse in activity.
Which patent classes dominate logic and memory device filings?
G11C, covering static and digital memories, is the clear leader at 4.6% of all 366,872 records, more than three times the share of the next largest class, H01L semiconductor devices at 1.4%. H10B memory device manufacture (1.3%), H10D general semiconductor devices (0.6%) and G06F data processing (0.6%) follow well behind. Smaller classes such as H10W and H10P sit under 1%, marking them as comparatively under-claimed relative to the core memory-cell classes.
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 Logic & Memory Devices Patent Landscape covering 2015–2026, data cut-off 2026-08-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
