Whoop sues Indian wearable brand behind Luna Band
Whoop has filed a trademark infringement lawsuit against Nexxbase Technologies, the company behind the recently launched Luna Band. The legal action, submitted on January 22 in Delaware federal court, names both Nexxbase and its marketing arm as defendants, along with the brand identities Luna, LunaZone, and Noise.
Whoop’s case centres on branding and product identity
Court records confirm that the case is based on alleged violations of Whoop’s trademark rights. This usually means that the company believes the defendants’ branding, product naming or overall look might confuse consumers or dilute Whoop’s established identity in the fitness wearable space. In this case, that concern is focused on the Luna Band, a recent product launched under the Noise and Luna brands.
Luna Band was introduced ahead of CES 2026 and positions itself as a screenless, subscription-free fitness tracker. This setup closely mirrors Whoop’s own formula, which also relies on a minimalist design and off-device data processing. Visually, the Luna Band adopts a fabric strap, a pill-shaped module, and a buttonless interface, all of which align with Whoop’s aesthetic choices. Even the product messaging around recovery, strain and continuous health tracking leans in a similar direction.
A pattern in Whoop’s legal strategy
This is not the first time Whoop has resorted to legal means to protect its design identity. A similar case is ongoing against Polar, where Whoop alleges that the screenless Polar Loop bands use a form factor and strap system that is too close to its own. That case also involves claims around trade dress, which refers to the overall visual presentation of a product.
The Luna Band, which is targeted at a more price-sensitive market and does not require a monthly fee, could be seen as a threat to Whoop’s niche. From Whoop’s perspective, allowing a rival product with a similar visual identity to expand under different branding could gradually erode its position as the reference point in minimalist fitness wearables.
This case is still in its early stages. Summons have been issued, and court filings show that a jury trial has been requested.
Luna Band gains attention in US and beyond
While the Luna Band is primarily an Indian-market product, its push into international awareness has been growing. Its presence at CES 2026 raised its profile, and coverage across mainstream media and fitness tech blogs has made it a recognisable alternative to Whoop.
The case could serve as a signal to other wearable makers that Whoop intends to defend its look and model aggressively. With the wearable market evolving rapidly and more brands experimenting with screenless, passive data capture, this will not be the last legal standoff over what defines a product’s visual DNA.
