MiiR Sues Tesla for Allegedly Copying Tumbler Lid Design

MiiR, a Seattle-based manufacturer of drinkware, has initiated legal proceedings against automotive giant Tesla. The lawsuit, lodged in the US District Court in Seattle on May 28, accuses Tesla of infringing upon MiiR's patented design for its tumbler lid. MiiR asserts that Tesla's "On The Road Tumbler" closely resembles its own "360 Traveler Tumbler" in both lid construction and overall aesthetic.

The core of the dispute centers on MiiR's design patent, officially granted in February 2024. This patent protects a specific lid configuration described as "solid, saucer-shaped circular lid" with its circumference positioned perpendicularly to the container's sides. MiiR contends that an average consumer would likely be confused into believing the two lid designs are identical or substantially similar.

Beyond the lid, MiiR also points to Tesla's alleged copying of its distinctive vertical logo placement. The drinkware company has reportedly used this branding approach since at least 2011 on its products. MiiR argues that Tesla chose to replicate this visual element rather than develop an original design for its tumbler. The lawsuit seeks to obtain an injunction to halt sales of the contested Tesla product and to recover any profits derived from the alleged infringement. MiiR further suggests that Tesla had prior knowledge of their products, having potentially purchased or considered them before releasing their own tumbler.
