Endoscopic Modularity Patents: Who Leads, Where the Gaps Are 2026
- Filing has already peaked. Activity ran from 28 families in 2017 to a high of 150 in 2023, then declined toward 2026 — this is a maturing claim space, not an emerging one.
- The largest assignees are pulling back, not doubling down. Every top assignee in the recent-year momentum data shows a year-on-year decline, several down 80-100%, which points to consolidation around established designs rather than a fresh filing wave.
- Claims concentrate almost entirely in one IPC subclass. A61B accounts for 1,076 of 1,176 records; optical systems (G02B) and fluid-handling devices (A61M) are the only other subclasses with meaningful density.
Filing growth compares 2021 (97 records) with 2024 (81) — 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 1,176 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This review tracks patent families disclosing modular, single-use or detachable-component endoscopic systems — designs that separate an endoscope into interchangeable control, insertion-tube and head sections, or that swap a reusable handle for a disposable working end. The dataset spans filings from 2015 through the 2026 data cut-off, covering 1,176 patent families filed across major receiving offices led by the United States, the European Patent Office and WIPO’s PCT route.
Filing activity rose steadily through the late 2010s, peaked in 2023, and has since turned down — consistent with a technology area where the core architectural patterns are now claimed and later filings are refining rather than staking new ground. Because publication typically lags filing by around 18 months, the final one or two years in any trend chart will look weaker than they eventually turn out to be; the decline from the 2023 peak is real, but its exact depth for 2025-2026 is not yet fully visible in published data.
Filing trend and technology composition
Two views of the same 1,176 families: when they were filed, and which parts of the patent classification system they sit in.
A decade of filing, front-loaded toward 2023
Families rose from 28 in 2017 to a peak of 150 in 2023, with 2022 sitting at 137 — growth was already flattening before the peak, and the pull-back since is broad rather than confined to one assignee.
Concentration in surgical and diagnostic hardware
A61B (diagnosis and surgery) dominates at 1,076 of 1,176 records. G02B (optics, 138) and A61M (body-fluid devices, 112) are secondary but real clusters; H04N (video/imaging communication, 40), A61C (dentistry, 21), F21V (lighting components, 18), A61L (sterilising, 15) and G16Z (application-specific computing, 15) are all thin enough to represent open rather than occupied ground.
Shares are the percentage of the 1,176 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Modular endoscope (US20240335095A1, Sigma Engineering Concepts LLC, filed 2024)
A modular endoscope system is described which can allow a single modular endoscope system to perform several imaging and therapeutic procedures. The modular endoscope system includes one or more control sections, one or more insertion tube sections, and one or more head sections that are interchangeable and combinable with respect to an intended endoscopy procedure. These sections may be connected, and signals may transmit electronically between the sections. Further, the modular endoscope system may incorporate a "scope-by-wire" control system for the distal end of the insertion tube section.Abstract text as filed; truncated where noted in the original record.

Citation counts accumulate over time, so older filings such as US6017322A and US6770027B2 lead the table by volume of citations rather than by current relevance — treat them as foundational reference points, not as evidence of what is being actively litigated or licensed today.
Each row carries its publication number; clicking a row searches Eureka by that number.

Three patterns stand out once families, IPC codes and citation data are read together.
The wave has crested
Activity climbed for six straight years before turning down after 2023. Combined with the recency lag in published data, this looks less like a collapsing market and more like an architecture that has settled — most of the obvious control/insertion-tube/head-section splits are already claimed.
Even the leaders are filing less
Every assignee tracked in recent-year momentum — from Olympus Medical Systems to Boston Scientific International — shows a year-on-year decline, several falling to zero. That is a signal of a settled competitive set defending existing filings rather than racing to expand them.
One subclass carries the field
A61B's share leaves the remaining seven IPC subclasses thin by comparison. G02B and A61M are large enough to be genuine sub-fields; H04N, A61C, F21V, A61L and G16Z each sit under 40 records, which is where less-crowded claim territory is likely to be found.
US-centred, with a real European and PCT presence
The United States receives more than double the filings of the European Patent Office, but Germany (52) and Austria (40) each add meaningful national-phase volume on top of the EPO and PCT totals — worth checking before assuming US-only freedom to operate.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to endoscopic device modularity and standardization, with the prior art for and against each one.
Who is still active, and where the field is thin
Momentum data shows a shrinking group of active filers rather than new entrants scaling up.
Olympus Medical Systems
The only tracked assignee still filing more than a handful of families in the latest year, though even this leader is contracting rather than expanding its filing rate.
Noah Medical Group
A steep drop from prior-year volume suggests either a shift to trade-secret protection, a pause after an initial filing burst, or reallocation toward adjacent product lines not captured by this search string.
A cluster at or near zero
Several previously active assignees, including Boston Scientific International and Medtronica, show no filings in the latest tracked year — consistent with the broader post-2023 slowdown rather than any single company's retreat.
| Assignee | Recent year | YoY |
|---|---|---|
| Olympus Medical Systems Corp. | 4 | -33% |
| Noah Medical Group | 2 | -89% |
| Jetross Achima | 1 | -83% |

Where to take this next
The landscape data points to specific next steps depending on whether the goal is filing, licensing or freedom-to-operate review.
Check freedom to operate in the thin IPC subclasses
G16Z, A61L and F21V each carry 15-18 records against A61B's 1,076 — before designing around a sterilisation-integrated joint or a scope-by-wire control interface, confirm which of those thin subclasses actually reads on the intended design.
Run a freedom-to-operate search in EurekaTrack the assignees still filing, not just the historical leaders
Citation counts favour older records like US6017322A and US6770027B2; the more decision-relevant signal is which assignees are still filing in the latest year at all, and Olympus Medical Systems is currently the only one filing above a handful.
Monitor assignee activity in EurekaCommon questions on this landscape
In this dataset, the qualifying claims describe endoscopic systems built from interchangeable sections — typically a reusable control or handle section paired with a disposable insertion tube or head section — or systems where a working module detaches entirely for single use. The search string specifically captures 'modular endoscope', 'single-use endoscope' and 'detachable module' language, so the corpus is narrower than all endoscopy patents generally. Most of these families sit in IPC subclass A61B, which covers diagnostic and surgical instruments.
No. Filings rose from 28 families in 2017 to a peak of 150 in 2023, then declined toward 2026, and every leading assignee tracked in the recent-year momentum data shows a year-on-year drop. Publication lag of roughly 18 months means the very latest years will always look weaker than they eventually prove to be, but the downturn starting after 2023 predates that lag window and looks structural rather than a reporting artefact. This pattern is typical of a technology area where the core architectural approaches have already been claimed.
Olympus Medical Systems is the only tracked assignee still filing above a handful of families in the latest year, though even its filing rate fell 33% year-on-year. Other previously active assignees, including Noah Medical Group, Jetross Achima, Boston Scientific International and Medtronica, show sharp declines or zero filings in the latest year. This suggests a consolidating field where established players are defending prior filings rather than expanding claim coverage.
The IPC composition points to several under-claimed branches: application-specific computing tied to modular scope assembly (G16Z, 15 records), sterilisation methods integrated into detachable joints (A61L, 15 records), and lighting-module attachment mechanisms (F21V, 18 records) are all thin compared to the 1,076 records in the core A61B subclass. A narrowly drafted claim in one of these areas is less likely to run into dense prior art than a claim on the general control-insertion-head architecture, which is now heavily occupied.
Not necessarily. The most-cited records in this corpus, such as US6017322A and US6770027B2, were filed years ago and have accumulated citations simply by being in the field longer — citation counts inside any searched corpus structurally favour older documents. A patent's citation count is a better signal of its historical influence on how the field developed than of whether it is being actively enforced, licensed, or designed around today.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
