Network Detection and Response Patents: Who Is Filing and Where the Field Is Headed
37.5% of all 1,334 records sit with just five assignees, so the field reads as concentrated at the top rather than fragmented. Publications rose from 92 in 2017 to a peak of 161 in 2022. Comparing the two most recent complete years available, 2021 (86) to 2024 (60), filings fell 30% — a real signal, but one that predates the still-filling-in 2025-2026 window, since publication typically lags filing by around 18 months.

Questions practitioners ask about this field
Who holds the most patents in network detection and response?
The dataset’s assignee ranking shows a single leader with 190 records, well ahead of the fifth-placed assignee at 28 and the tenth-placed assignee at 17. The top five assignees combined hold 37.5% of all 1,334 records in scope, and the top ten hold 45.4%. That still leaves more than half the field distributed across a long tail of smaller filers, so a competitive watch list built only around the top names will miss a substantial share of activity.
Is patent filing in network detection and response growing or slowing?
Filings rose from 92 in 2017 to a peak of 161 in 2022. Comparing the two most recent complete years, 2021 (86) and 2024 (60), filings fell 30%. However, 2025 and 2026 counts are still incomplete because publication typically lags filing by roughly 18 months, so it is premature to call the field in decline based on the most recent two years alone; the safer read is a plateau after the 2022 peak.
What technology areas dominate network detection and response patents?
H04L, digital information transmission, appears on 81.6% of the 1,334 records, and G06F, electric digital data processing, appears on 58.5%. G06N, AI-based computing, has grown to cover 30.0% of records, reflecting how anomaly-scoring and behavioural-model techniques have become a standard claim layer rather than a separate filing category. Narrower classes like G06V (image/video recognition) and G08B (signalling and alarms) sit under 2% each, marking comparatively open territory.
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 Network Detection and Response covering 2015–2026, data cut-off 2026-07-31.
