LEGO Smart Play Patent Lawsuit: What Builders Should Know

The LEGO Smart Play patent lawsuit adds a legal dispute to one of the company’s newest play systems. May Patents Ltd. filed a complaint in the Eastern District of Texas on September 15, 2026, alleging that LEGO’s SMART Brick, SMART Charger, interactive minifigures, and SMART Tags infringe three US patents.

Those allegations are not a court ruling, but the case matters because Smart Play links familiar brick-built models with sensors, wireless communication, lights, sound, and movement-aware responses. For builders, the dispute centers on the technology layer that makes physical actions trigger electronic feedback.

What the Smart Play lawsuit alleges

The complaint names five LEGO entities and cites US patents 11,192,002, 12,095,277, and 12,288,992. The patents concern methods in which a device senses motion and produces a response. May Patents alleges that LEGO received notice of the patents in February, before Smart Play products reached the market, and that later sales infringed the claimed technology.

The important distinction is that this is an allegation at the opening stage of litigation. The filing does not establish infringement, determine damages, or show that Smart Play products will change. It frames the questions that the court will now examine.

Why the case matters to LEGO builders

Smart Play is designed to keep the screen secondary while the model remains the main interface. The SMART Brick reacts to movement and nearby components, letting a spacecraft, creature, or scene produce feedback during hands-on play. A patent dispute around that architecture could therefore affect more than one set: it concerns the shared platform connecting compatible themes.

Final Thoughts

For now, builders should treat the LEGO Smart Play patent lawsuit as an active claim, not a verdict. The useful takeaway is how much modern LEGO play can depend on the relationship between physical construction and embedded electronics—and how closely that relationship can intersect with existing technology patents.
