Munchkin Wins Favorable Decision in Patent Infringement Case Against TOMY International Inc.

TOMY International Inc. and its “The First Years Brands” Simply Spoutless Cup

Found to Infringe Munchkin’s Miracle® 360° Sippy Cup Patent

LOS ANGELES--()--Munchkin, Inc. (“Munchkin” or “the Company) the beloved baby lifestyle brand owned by WHY Brands Inc. and the Company behind the most innovative gear and lifestyle products for children, mothers and caregivers, announced today a favorable decision by the U.S. District Court (Northern District of Illinois Eastern Decision) that found literal patent infringement by TOMY International Inc. (“TOMY”).

On January 25, 2024, in the U.S. District Court (Northern District of Illinois Eastern Division), Judge Charles P. Kocoras granted Munchkin’s motion for summary judgment, ruling that defendant TOMY, and its Simply Spoutless Cup sold under its “The First Years” brand, infringed at least one of Munchkin’s patents for Munchkin’s innovative Miracle® 360° Sippy Cup.

“We are pleased with the ruling by the U.S. District Court, and its recognition of Munchkin’s decades-long investment in innovation,” said Steven B. Dunn, Founder and Chief Executive Officer of Munchkin. “Munchkin has invested immense resources into its R&D efforts to create the most innovative gear and products for children, mothers and caregivers as demonstrated by Munchkin’s 340+ patents. We will continue to vigorously protect and enforce our intellectual property rights, and continue to lead the way on innovation.”

Munchkin is committed to protecting its innovations through its effort in securing patent protection in the United States and other territories internationally. Unlike traditional sippy cups, Munchkin’s multi-patented Miracle® 360° Sippy Cup was designed to eliminate messes and support children’s dental health simultaneously as the cup’s dentist-approved spoutless design allows spill-free drinking from all sides and automatically seals once the child stops drinking.

The court left open that TOMY’s Simply Spoutless Cups may also infringe additional claims under the asserted Munchkin utility patent as well as a second Miracle® 360° Sippy Cup patent, a design patent, as asserted by Munchkin.
