Compact & Desktop Cobot Patent Snapshot 2026
The compact and desktop cobot patent corpus is nascent, with activity concentrated almost entirely in 2023 and dominated by a single applicant. The field is highly concentrated at the filing level, leaving the competitive and technology landscapes largely open.
A two-player field with one dominant filer
Shenzhen Yuejiang Technology holds 5 of the 6 patent families in scope, making it the commanding leader in compact and desktop cobot filings by a wide margin. Beijing Xiaomi Robot Technology accounts for the remaining 1 patent family, rounding out a two-player ranking.
The top five filers collectively hold 100% of the ranked applicants visible in this query’ combined total — a concentration level that signals an extremely early-stage, thinly filed space rather than a mature competitive battleground. There is effectively no second tier of challengers visible in the current corpus.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Shenzhen Yuejiang Technology Co., Ltd. | 5 | |
| 2 | Beijing Xiaomi Robot Technology Co., Ltd. | 1 |
Europe (EPO) as the primary filing jurisdiction — indicating an outward IP strategy aimed at key export markets.
The most recent filing windows should be treated as under-counted due to standard patent publication lag; the apparent absence of activity after 2023 does not reflect actual R&D pace. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single-year burst in 2023 across manipulator-focused branches
All 6 patent families in scope were filed or published in 2023, with no recorded activity in any prior or subsequent year within the observation window. The technology mix is narrow and centered on robotic manipulator hardware.
Annual filing trend
The entire corpus clusters in 2023. Years before and after show zero activity, though post-2023 figures should be treated as incomplete given publication lag. This is consistent with a field at its earliest formation stage rather than one with sustained multi-year momentum.

B25J (Manipulators & robots) is visible in the technology composition, appearing across all 6 patent families. H02K (Electric motors & generators) appears as a secondary branch, reflecting the actuator and joint-motor content typical of compact cobot design. G01D (Measuring, general & recording) is present at a lower level, pointing to sensor-integration and feedback elements.

Collaborative robot arm and joint module
The present disclosure provides a collaborative robot arm and a joint module. The joint module includes a housing, a driving assembly, and a multi-turn absolute encoder. The joint module detects the angular position of the output shaft and records a number of rotating revolutions of the output shaft only by means of the multi-turn absolute encoder.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Shenzhen Yuejiang Technology
Yuejiang holds 5 patent families, covering B25J 9 (robot structure/control), B25J 13 (control with sensing), and B25J 17 (joints/articulations) — all 5 families touching each of these sub-branches, indicating a broad and systematic approach to compact cobot architecture. Momentum is classified as a new entrant with recent filings of 5, reflecting the field’s 2023 inception rather than a multi-year ramp.
families: 5Beijing Xiaomi Robot Technology
Xiaomi’s robot subsidiary holds 1 patent family, focused on B25J 17 (joints/articulations) and B25J 9 (robot structure), suggesting an interest in the joint-module layer of compact cobot design. As a new entrant, its single filing establishes a presence without yet indicating a sustained IP campaign in this specific segment.
families: 1Frequently asked questions
The current evidence base contains 6 patent families in scope. This is a very small corpus, consistent with a nascent field that began generating IP activity in 2023.
Shenzhen Yuejiang Technology is the leading filer with 5 patent families. Beijing Xiaomi Robot Technology is the only other applicant, holding 1 patent family.
Europe (EPO) leads with 3 patent records, followed by the United States with 2 and China with 1. Both applicants are China-headquartered, making the EPO-first profile indicative of an export-market IP strategy.
Three branches appear: B25J (Manipulators & robots), covering all 6 patent families; H02K (Electric motors & generators), appearing in 3 records; and G01D (Measuring, general & recording), appearing in 2 records.
Yes. B25J 19 (safety devices and sensing for manipulators) and B25J 15 (grippers and end-effectors) are absent from the current corpus despite being technically relevant to compact cobot applications. These represent under-served adjacent branches, though they should be assessed for commercial opportunity independently.
All 6 patent families in scope share a 2023 publication or filing date. Years after 2023 appear empty partly due to standard patent publication lag — applications filed in 2024 and 2025 may not yet be publicly visible. The 2023 cluster marks the observed inception of this specific patent category.

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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
