May Patents Ltd. filed May Patents Ltd. v. LEGO A/S et al., No. 4:26-cv-01276 (E.D. Tex. Sherman Division), on September 15, 2026.
Patents and accused products
The complaint asserts U.S. Patents 11,192,002, 12,095,277, and 12,288,992, each in a family titled Device for displaying in response to a sensed motion (with the '992 patent as a method counterpart). The accused products are LEGO Smart Play products identified in the complaint.
What the patents cover
U.S. Patents 11,192,002; 12,095,277; and 12,288,992 cover a portable device that senses motion and then displays content or runs a related function in response - toys or gadgets that light up, show images, or run a routine when they detect movement.
U.S. Patent 11,192,002 covers a device with a signaling means, a motion sensor, and logic that activates or controls the signaling means in response to sensed motion. It may be shaped like a play ball or handheld unit, battery-powered (including inductive or kinetic charging), and may display a count or peak acceleration value when a threshold is crossed.
Asserted claims. The complaint identifies at least claim 1 of each of the '002, '277, and '992 patents. Lead claim 1 of the '002 patent is summarized below; claim 1 of the '277 and '992 patents is in the same family.
Claim 1 of the '002 patent, as quoted in paragraph 36 of the complaint, recites an accelerometer, display, wireless RF receiver, processor and software, rechargeable battery, and induction-based contactless charger. It requires displayed information to respond to the accelerometer's output. The quoted claim does not require the device to display information while it is charging.
What the lawsuit is about
May Patents is mapping LEGO's Smart Play line onto motion-responsive display and device claims. The case is an East Texas consumer-electronics assertion against a major toy platform.
What it means
Watch whether LEGO contests claim scope and whether Smart Play hardware and software meet each limitation of claim 1. The filing does not establish infringement; it opens discovery and motion practice.
What to watch next
Watch for LEGO's answer or Rule 12 motions after service, and for any related May Patents filings against other connected-toy products.
