Motion Preservation Disc Patents: Top Companies & Trends 2026
Motion Preservation and Disc Replacement Patents
18.2% concentration at the top. The five leading assignees combine for 1,136 of 6,245 records in scope — a real cluster, but well short of dominance, leaving room for a long tail of single- and few-filing entrants. Filings rose from 173 in 2017 to a peak of 204 in 2020, then declined to 100 by 2024, a -37% move across 2021-2024. Treat 2025 and 2026 figures as provisional given the roughly 18-month publication lag.

Common questions on motion preservation and disc replacement patents
Who holds the most patents in artificial disc replacement?
The dataset’s assignee ranking shows a single leading filer with 361 records, well ahead of the fifth-ranked assignee at 139 and the tenth at 101. That leaves the top five assignees combining for 18.2% of all 6,245 records in scope, and the top ten for 26.7%. The remainder is spread across a long tail of the ranked field and beyond it, so no company controls a majority of the claim space.
Is patent filing in disc replacement technology slowing down?
Filings peaked in 2020 at 204 and fell to 100 by 2024, a -37% decline across the 2021-2024 span that can be treated as complete data. However, publication lags filing by roughly 18 months, so the lower counts shown for 2025 and 2026 are still filling in and should not be read as evidence of a further drop. The 2021-2024 trend is the most reliable signal currently available.
What patent classes matter most for artificial disc devices?
A61F, covering implants and prostheses, appears on 64.4% of the 6,245 records in scope, making it the densest single class. A61B, covering diagnosis and surgery, follows at 51.8%, reflecting how closely device claims are tied to surgical method claims. Smaller classes such as sterilisation (A61L), electrotherapy (A61N) and healthcare informatics (G16H) sit in single digits and represent comparatively open, less-contested claim 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.
