Endoscopic Wireless Connectivity Patents: Leaders & Trends 2026
- Filing peaked in 2019 at 46 families and has declined since, with the midpoint year 2022 at 20 — a flat-to-declining trend rather than a growth curve.
- A61B dominates the technology mix with 301 of 374 records classified under diagnosis and surgery, dwarfing image processing (45), pictorial communication (32) and antennas (25).
- United States and China lead filing venues at 116 and 110 records respectively, with Europe, WIPO, Germany and South Korea trailing well behind.
What this landscape covers
This landscape tracks 374 patent families published between 2015 and mid-2026 that combine endoscopic devices with wireless connectivity — capsule endoscopes, wireless image transmission and capsule telemetry. The search deliberately spans device classifications (A61B, A61M, G02B) alongside the connectivity layer (H01Q antennas, H04N pictorial communication, G06T image processing, G06N AI models), so the dataset captures both the physical instrument and the data path around it.
Because publication typically lags filing by around 18 months, the 2025-2026 counts in any trend view are understated relative to what has actually been filed. The composition and assignee patterns below are based on the fuller history through 2019-2023, where filing activity is more completely captured.

Filing trend and technology composition
Two views of the same 374-family dataset: how filing volume has moved year over year, and how the underlying technology splits across IPC subclasses.
A peak in 2019, then a slow decline
Filings ran at 35 in 2017, rose to a peak of 46 in 2019, and had fallen to 20 by the 2022 midpoint. The most recent years read lower still, partly because of publication lag rather than a sudden stop in filing.
Diagnosis and surgery classifications dominate
A61B accounts for 301 of the 374 records — the large majority. Image processing (G06T, 45), pictorial communication (H04N, 32), body-fluid devices (A61M, 27), antennas (H01Q, 25), AI-based computing (G06N, 24), material analysis (G01N, 14) and optics (G02B, 14) form a long tail of supporting connectivity and processing subclasses around that core.
Shares are the percentage of the 374 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Wireless capsule endoscope and power supply control method thereof (US20150011829A1)
The filing describes a wireless capsule endoscope with automatic power-consumption adjustment: a capsule casing housing a light generator, an opto-electronic switching starter, a posture sensor, an illumination unit, an image processing device and a radio-frequency transmission unit, with the power supply driven by the light generator to control energy use during operation.Filed by Ankon Technologies, dated 2015-01-08 — among the earliest records in this dataset and a useful baseline for what capsule-endoscope power and RF architecture looked like at the start of the filing window.

Citation counts favour older filings that have had more time to accumulate references within the searched corpus; they signal historical influence rather than which technology is most active today.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

Three read-outs from the trend, the technology split and the venue data, translated into what they imply for anyone deciding where to file or search next.
The category has cooled since 2019
Filing activity rose to a 2019 peak of 46 families and had roughly halved by 2022. That is a flat-to-declining trajectory, not an emerging one — new entrants are filing into a category where claim space has already been staked out rather than one still forming.
Claim density sits overwhelmingly in diagnosis and surgery
A61B's share leaves the connectivity-specific subclasses — antennas, pictorial communication, AI processing — comparatively thin. That imbalance suggests the wireless and data-handling layer is less crowded than the device layer itself.
US and China are near parity as filing venues
The two lead venues sit close together, with Europe, WIPO, Germany and South Korea filed at meaningfully lower volumes. A dual US/China filing strategy tracks where competitors are already establishing coverage; PCT and EPO filings remain comparatively sparse.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to endoscopic device wireless connectivity and iot, with the prior art for and against each one.

Only 6 co-assignee pairs appear across the dataset, each tied to a small number of shared filings — co-development in this space is the exception, not the norm.
Who is filing, and where activity has gone quiet
Assignee activity in this dataset is broad but not deeply concentrated, and recent-year momentum has dropped to zero across the assignees tracked here — consistent with the overall decline from the 2019 peak.
Recent-year filing has gone flat across the board
Every assignee tracked for year-over-year momentum, including Olympus and Neptune Medical, shows zero families in the latest year, with at least one recording a -100% year-on-year change. This mirrors the overall trend decline rather than pointing to a single firm pulling back.
Collaboration is limited to a handful of pairings
The strongest co-assignee pairs each involve 3 shared filings — modest by any measure. Most activity in this dataset is filed by single assignees rather than through joint development arrangements.
Ankon Technologies anchors the early end of the window
The representative filing on capsule-endoscope power control dates to the first week of the coverage window, giving a concrete reference point for baseline architecture before the 2019 filing peak.

Where to take this next
The trend and composition data point to a mature, slowing filing category with specific under-claimed branches rather than an open field. Two directions follow from that.
Map the antenna and RF telemetry claims in detail
H01Q and low-power telemetry sit well below A61B in volume. A focused search on antenna miniaturisation and RF power-management claims would clarify whether that gap is genuine white space or simply filed under different classifications.
Explore this branch in EurekaTrack the assignees still active despite the overall decline
Zero recent-year momentum across tracked assignees does not mean zero underlying R&D — publication lag means 2025-2026 filings are still arriving. Watching which assignees resume filing first will show who is repositioning for the next cycle.
Set up assignee tracking in EurekaCommon questions about this landscape
The filing trend in this dataset peaked at 46 families in 2019 and had fallen to 20 by the 2022 midpoint. This does not necessarily mean underlying research has slowed — publication typically lags filing by around 18 months, so the most recent one to two years in any trend chart will always understate true activity. What the decline does suggest is that core claim space around A61B-classified capsule and imaging architectures was staked out early, pushing later filers toward narrower or adjacent claims.
Assignees tracked in this dataset include Olympus, Neptune Medical, Ankon Technologies and several university and research entities, but recent-year momentum data shows zero filings in the latest year across the assignees tracked for that measure. This points to a field with broad participation rather than one or two firms holding a dominant, growing share — no single assignee's momentum stands out as currently accelerating.
A61B, covering diagnosis and surgery, accounts for 301 of the 374 records in this landscape — by far the densest classification. Supporting areas like antennas (H01Q, 25 records), AI-based computing (G06N, 24) and material analysis (G01N, 14) carry far fewer filings, which is where claim space is comparatively open relative to the crowded device-level claims in A61B.
Receiving-office data shows the United States (116) and China (110) as the two leading venues, filed at similar volumes, with Europe (43), WIPO/PCT (36), Germany (9) and South Korea (9) trailing well behind. A filing strategy that prioritises US and China coverage tracks where existing competitors have already built out protection, while PCT filing volume remains comparatively low relative to those two national routes.
US20150011829A1, assigned to Ankon Technologies and dated 2015-01-08, claims a specific combination of a capsule casing, light-generator-driven power supply, opto-electronic switching starter, posture sensor, illumination unit, image processing device and RF transmission unit. Designs that avoid that specific power-supply-driven-by-light-generator architecture, or that use a different power-adjustment mechanism, sit outside its narrow claim scope. It is one data point among 374 families and should be checked against the fuller citation and claim set before concluding freedom to operate.
