These startups both released groundbreaking induction stoves. Now they’re embroiled in a lawsuit
Copper is suing Impulse, alleging patent infringement over the design of induction stoves with integrated batteries for enhanced performance and grid support.Summary
Copper, a startup specializing in next-generation induction stoves, has filed a patent infringement lawsuit against Impulse Labs in Delaware federal court. The dispute centers around a shared design feature: both companies incorporate batteries into their stoves. This innovation boosts performance, simplifies installation, and provides energy storage capabilities to alleviate strain on the electric grid. Copper claims to have pioneered this technology, securing its first patent in 2022 and subsequent patents in 2024 and 2025, backed by $35 million in venture funding. Impulse, which launched in 2022 and has raised $25 million, maintains it disagrees with Copper’s characterization of events and anticipates a favorable outcome in court. The integrated battery design offers significant benefits, potentially enabling easier and more affordable home energy storage and supporting grid stability by storing excess renewable energy for peak demand.
