Surgical Navigation Patents: Leaders & Filing Trends 2026
- Filing has cooled since a 2020 peak of 66 families. The midpoint year (2022, 39 families) already sits below that peak, and the two most recent full years continue the decline — this reads as a maturing claim space, not a growing one.
- Image processing is the dominant adjacent art. 109 of 400 families also carry a G06T image-data-processing classification, far ahead of implants, fluid devices or optics — registration and visualization algorithms are where the crowding is.
- The US is the dominant filing venue by a wide margin. 190 records route through the USPTO versus 94 at the EPO and 39 via WIPO/PCT — a design freedom check outside the US faces a noticeably thinner prior-art wall.
Filing growth compares 2021 (53 records) with 2024 (38) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 400 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks 400 patent families filed between 2015 and mid-2026 that combine surgical navigation, image-guided surgery or computer-assisted surgery language with claims on intraoperative registration, instrument tracking, augmented-reality surgery, 3D surgical planning or image-guided navigation, classified under A61B34/20, A61B90/00 or A61B34/10. The scope is narrow by design: it isolates the navigation and registration layer of image-guided surgery rather than the broader surgical-robotics or implant-design fields that often sit adjacent to it.
Because publication lags filing by roughly 18 months, the most recent one to two years in any trend line understate true filing activity — the 2026 figure in particular should be read as a floor, not a ceiling.
Filing trends and technology composition
Two views of the same 400 families: how filing volume has moved year over year, and which adjacent IPC subclasses show up alongside the core navigation classifications.
A 2020 peak followed by a decline
Annual filings rose to 66 in 2020 before easing back; by the 2022 midpoint they had already fallen to 39, and the trend through 2026 (partial year, 3 filings recorded so far) continues that softer trajectory. Read the tail years as undercounts given publication lag rather than as a genuine drop-off.
Image processing is the largest adjacent art
Every family in this set carries an A61B diagnosis-and-surgery classification by construction. Beyond that, G06T image-data-processing appears in 109 families — more than double the next-largest adjacent class, A61F implants at 19 — followed by smaller pockets in body-fluid devices, general digital processing, optics, magnetics and sterilisation. The concentration in G06T signals that registration, tracking and visualization algorithms carry more filing density than the hardware side of navigation systems.
Shares are the percentage of the 400 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Image-Guided Navigation System for Targeted Delivery of Spinal Cord Therapies
Image-guided navigation for spinal cord treatments and therapies are described. The image-guided navigation is augmented with anatomical measurement data related to spinal cord and vertebral anatomy. From these data and medical image data, an augmented model of spinal cord anatomy is generated and/or navigation data can be generated for localizing spinal cord structures, such as by mapping the anatomical measurement data to the medical image data. The augmented model data and/or navigation data can be used for surgical navigation, stimulation parameter setting, electrode configuration selection, pre-surgical planning, surgical visualization, and so on.Filed by Mayo Foundation for Medical Education and Research, published 2022-12-08 as US20220387114A1.

Three read-throughs from the trend, classification and venue data, useful for deciding where to file next and where prior art is thinnest.
The category has passed its filing peak
Volume peaked in 2020 and has trended down since, with the 2022 midpoint already well below peak. Even allowing for publication lag understating the last one to two years, this is not a category still accelerating — it is one where the core registration and tracking claims are increasingly staked out.
The crowding is in the software layer
Image-data-processing classifications outnumber every other adjacent art combined. Optics (12), magnetics (9) and sterilisation (6) barely register by comparison, which suggests the hardware and sensing side of navigation systems has drawn far less claim density than the registration and visualization algorithms.
The US carries the bulk of the prior art
Nearly half of all records route through the USPTO, with the EPO a distant second at 94 and China at only 15. A freedom-to-operate check weighted only to the US will miss a category where non-US prior art is comparatively sparse.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to surgical navigation technology landscape, with the prior art for and against each one.
Who is filing, and who has slowed down
Momentum data shows a field where several previously active filers have gone quiet in the most recent year, alongside co-filing relationships concentrated around a small number of orthopaedic and surgical-robotics groups.
Smith & Nephew Asia Pacific holds steady
The Smith & Nephew Asia Pacific entity shows one filing in the latest year with no year-over-year change, and appears in two of the strongest co-assignee pairs in the dataset alongside other Smith & Nephew entities — consistent with a coordinated multi-entity filing strategy rather than a single inventing group.
Globus Medical has gone to zero in the latest year
Globus Medical shows no filings in the most recent year, a full reversal from prior activity. Medtronic Navigation similarly shows zero in the latest year, though without the same YoY collapse figure, suggesting a broader pause among established spine-and-navigation filers rather than one company's retreat.
Intuitive Surgical Operations also shows zero
Intuitive Surgical Operations records no filings in the latest year against a -100% year-over-year change, mirroring the pattern at Globus Medical. Marco Surgical, by contrast, still shows one filing in the latest year — a small but active signal against an otherwise quiet field.
| Assignee | Recent year | YoY |
|---|---|---|
| Marco Surgical, Inc. | 1 | — |
| Smith & Nephew Asia Pacific Pte. Limited | 1 | 0% |
| Globus Medical, Inc. | 0 | -100% |

Where to take this analysis
The trend and classification data point to a maturing core claim space with unevenly distributed geographic coverage. The next steps depend on whether the goal is freedom-to-operate, licensing or new filing.
Run a freedom-to-operate check outside the US
With 190 of 400 families routed through the USPTO against only 15 in China and 15 in Canada, a clearance review limited to US prior art will systematically overstate how open those other markets are.

Registration and AR-visualization claims sit inside the densest adjacent classification in this dataset. A new algorithmic claim in this area needs a citation check against the most-cited image-guided surgery records specifically, not just the A61B core.

Filing activity in this dataset is concentrated among a group of orthopaedic and surgical-robotics companies, including Smith & Nephew entities, Stryker, Medtronic Navigation, Globus Medical and Intuitive Surgical Operations, alongside academic and research filers such as Mayo Foundation. Several of the most active historical filers show zero filings in the latest recorded year, which may reflect either a genuine pause or the roughly 18-month lag between filing and publication. No single assignee dominates the full 400-family set outright; the pattern is concentration among a handful of established names with a long tail of smaller filers behind them.
Based on this dataset, filing volume peaked in 2020 at 66 families and has declined since, with the 2022 midpoint already down to 39. That points to a category that has passed its peak filing rate rather than one still accelerating, though the most recent one to two years are understated because of publication lag and should not be read as a hard drop to near zero. The more reliable read is that core registration and tracking claims are increasingly staked out, pushing new filers toward narrower clinical applications.
The core classifications are A61B34/20, A61B90/00 and A61B34/10, covering surgical navigation systems, instrument tracking and computer-assisted surgery. Beyond that core, G06T (image data processing and generation) appears in 109 of 400 families, making it by far the largest adjacent classification — well ahead of A61F implants at 19 or A61M fluid devices at 16. Anyone drafting claims in registration, AR overlay or 3D planning should check G06T-classified prior art specifically, not just the A61B core.
The classification data shows comparatively thin coverage in areas like magnetic instrument tracking, sterilisable navigation optics, and AR-overlay claims tied to fluid-delivery or spinal-cord-therapy applications, relative to the dense core registration and tracking claims. Geographic white space also exists: China and Canada each show only 15 filings against 190 in the US, so claims drafted with those jurisdictions specifically in mind face a thinner prior-art wall. Neither observation guarantees patentability, but both indicate where a first claim is less likely to collide with existing filings.
The most-cited records in this dataset, including US20160191887A1 and US20180240237A1, are also among the older filings, which is typical: citation counts inside any searched corpus favour records that have had more years to accumulate references. A high citation count is a reasonable signal of historical influence on how the field's claims were framed, but it is not a reliable signal of which technology is commercially dominant today. Recent filings with few citations so far may still represent the current state of the art; they simply have not had time to be cited.
