Intracranial Stent Patents: Who Leads, Where the Gaps Are 2026
Intracranial stent and remodeling technique patents: who holds the ground and where it is still open
72.5% concentration. The top 5 of 43 ranked assignees account for 116 of the 160 records in scope — a field with a narrow, defensible core. Filings rose from 4 in 2017 to a peak of 12 in 2023, then eased into 2024 and beyond. Because publication lags filing by roughly 18 months, 2025 and 2026 figures are still filling in and should not be read as a slowdown. The 2021-to-2024 span — the last complete window — shows filings up 25%, from 4 to 5.

Common questions on intracranial stent patents
Who holds the most patents on intracranial stents and remodeling techniques?
One assignee leads the ranked field with 41 of the 160 records in scope, more than double the fifth-place count of 14. The top 5 of the 43 ranked assignees together hold 116 records, or 72.5% of all records in scope, so filing activity is concentrated rather than spread evenly. Beyond the top 10 — which reach 89.4% of records — the remaining assignees each hold small numbers, several just a single filing.
Is the intracranial stent patent field still growing?
Filing volume rose from 4 records in 2017 to a peak of 12 in 2023, and the 2021-to-2024 window — the most recent span with a complete publication picture — shows filings up 25%. Figures for 2025 and 2026 look lower only because publication typically lags filing by around 18 months, so those years are still filling in. Read the trend through 2024, not through the tail end of the chart.
What technology areas dominate intracranial stent patent claims?
A61F, covering implants and prostheses, appears on 83.1% of the 160 records, and A61B, covering diagnosis and surgery, appears on 63.7% — together they mark the device-and-procedure core of the field. Smaller but active pockets sit in coating and surface deposition (8.8%), sterilising methods (6.9%), body-fluid devices (6.3%) and alloy composition (4.4%). Because a single record can carry several IPC classes, these figures do not add to 100% and should each be read against the full 160-record base.
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 Intracranial Stents and Remodeling Techniques 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.
