Powered and Robotic Stapling Patents: Filing Trends and Who Holds the Claim Space
One assignee holds 165 of 351 records while the fifth-ranked holds 25 and the tenth just 2 — a steep drop rather than an even spread. Annual filings ran from 17 in 2017 to a peak of 30 in 2023, then 2024 closed at 28 — identical to the 2021 figure, for a flat 0% three-year span. 2025 and 2026 show fewer records only because publication has not caught up with filing; they should not be read as a slowdown.

Common questions on powered and robotic stapling patents
Who holds the most patents in powered and robotic surgical stapling?
One assignee leads the ranked field with 165 of the 351 records in scope, far ahead of the fifth-ranked assignee at 25 and the tenth at 2. That gap indicates the leader has staked much of the core mechanical firing and articulation claim space rather than the field being evenly split. Anyone drafting new claims in this area should expect to design around that portfolio first, since it is the most likely source of blocking prior art on compression, firing and articulation mechanisms.
Is the patent filing rate in this field growing or slowing?
Filings were flat over the most recent complete comparison, with 28 records in 2021 and 28 again in 2024, a 0% change across that span, after a peak of 30 in 2023. This should be read as a stable, mature filing pace rather than growth or decline. Figures for 2025 and 2026 appear lower only because publication lags filing by roughly eighteen months, so those years are still filling in and are not yet reliable indicators of a slowdown.
What technology areas do these patents cover beyond the stapler mechanism?
A61B, the core surgery and diagnosis classification, appears in 84.6% of the 351 records, confirming the field is grounded in physical surgical-device claims. G16H, healthcare informatics, reaches 23.4% of records, and smaller shares appear in electric digital data processing, specific-application computing, business-data processing and counting mechanisms. Because a record can carry multiple IPC classes, these shares add up to more than 100% of the record total, reflecting sensing and software claims layered onto mechanical hardware.
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.
