Butterfly Network shares surge 20.94% after-hours after filing to dismiss Fujifilm lawsuit and launching updated iQ+ ultrasound.

Butterfly Network surged 20.94% in after-hours trading following two key developments. The company filed a motion to dismiss a patent infringement lawsuit by Fujifilm Sonosite, framing the legal action as a meritless attempt to distract from its innovation. Additionally, Butterfly introduced the Butterfly iQ+, an enhanced portable ultrasound device featuring faster imaging, longer battery life, and advanced tools like Needle Viz and AI-driven bladder volume calculations. The legal defense and product innovation underscored the firm’s commitment to protecting intellectual property and advancing its clinical platform, likely driving investor optimism. The lawsuit dismissal motion reduces potential legal risks, while the product launch highlights competitive differentiation in the POCUS market.
