When a patent's classification is six shades of one CPC subgroup, the claim's domain is unambiguous. Robart's grant US10860029B2 ("Method for controlling an autonomous mobile robot," issued December 8, 2020; inventors Harold Artes, Erwin Mascher, Reinhard Vogel) sits entirely inside the G05D 1/0xxx position-control family. There is no manipulator code, no vehicle tag complicating it — this is navigation control for a mobile robot, full stop.
The mechanism is the control loop that turns a navigation goal into safe motion: G05D 1/0238 (control by means of a map), 1/0274 (vision-based control), and 1/0044 (involving a remote operator or reference) together sketch a robot that follows a map, sees with cameras, and accepts external references. The 1/0088 code — characterized by the autonomy of the control — is the bucket examiners use for genuinely self-directed systems.
For the control beat, the lesson of a classification this pure is that the claim's inventive step is somewhere inside the control method itself, not in a clever cross-domain combination. The reader's job is to find which limitation — a specific map-following rule, a particular handling of the visual reference — carries the patentability. The breadth of the title ("controlling an autonomous mobile robot") is the opposite of the likely breadth of claim 1.
Robart is a German robotics-IP house whose navigation patents have shown up in licensing contexts around the consumer floor-robot market. From a portfolio view, that matters: a tightly-classified G05D control grant from a company with a licensing posture is an asset built to be asserted against anyone shipping mapped, vision-guided mobile robots. The narrowness of the claim and the breadth of the market are both features.
Caveats as always. Mobile-robot control is a mature field; a single broad-sounding claim won't survive without a specific recited mechanism. The classification establishes that this is navigation control — it does not establish that claim 1 reads on any given competitor. That requires reading the independent claim's limitations against the accused system.
For the file: a pure-G05D mobile-robot control grant from a licensing-oriented assignee. Pull US10860029B2 on PatentBear and read claim 1 for the one control step that distinguishes it — that limitation is the licensing lever.
