Resource Isolation Patents: Who Leads, Where the Gaps Are 2026
Resource Isolation and Overcommit Patents: Filing Trends and Who Controls the Claim Space
Concentrated at the top. The five most active filers hold 299 of 529 records in scope (56.5%), and the ranked ten hold 72.0% — a small group has staked out most of the claim space. Annual filings climbed from 27 in 2017 to a peak of 71 in 2022. Using the last fully comparable years, filings fell 27% from 45 in 2021 to 33 in 2024 — a real cooling, though not a collapse. 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a continuation of decline.

Common questions about this landscape
Who holds the most patents in resource isolation and overcommit?
One assignee leads clearly with 130 records, well ahead of fifth place at 25 and tenth place at 11. The top five filers combined hold 299 of the 529 records in scope, or 56.5%, and the top ten reach 72.0%. This is a field where a handful of infrastructure and chip vendors have built deep portfolios rather than one dominated by a single company alone.
Is patent filing in this space growing or slowing down?
Filing activity rose from 27 records in 2017 to a peak of 71 in 2022, then eased: comparing 2021 (45) to 2024 (33), the last fully comparable years, shows a 27% decline. Figures for 2025 and 2026 look lower still, but that is expected because publication typically lags filing by about 18 months, so those years are not yet complete. Treat the 2022 peak and the 2021-2024 decline as the reliable read, not the most recent bars on the chart.
What does US9836396B2 actually cover?
US9836396B2, assigned to MediaTek, claims a last-level cache controller that computes a weighted latency score per processor core from a latency sensitivity factor, off-chip latency factors and cache miss information, then aggregates those scores to decide whether to switch to a new cache-partition configuration. It is a specific control-logic approach to last-level cache partitioning, not a claim over cache partitioning generally. Anyone building a competing cache-partition controller should check whether their decision logic relies on a similarly weighted, per-core aggregated latency score before assuming clearance.
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 Resource Isolation and Overcommit covering 2015–2026, data cut-off 2026-07-31. 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.
