Stimulation for treating sleep disordered breathing
Summary
Third patent in Inspire Medical Systems core stimulation family (continuing from US11806526, which continues from US10898709). Covers further embodiments of the hypoglossal nerve stimulation method for OSA treatment, extending claims across additional stimulation protocol and therapy delivery contexts. Also named in the active Inspire v. Nyxoah patent litigation in Delaware District Court.
Why it matters
US11850424 is the third layer of Inspire's continuation patent strategy — each continuation adding claim scope to the foundational innovation. The three-patent family (US10898709 → US11806526 → US11850424) creates comprehensive IP coverage around the Inspire commercial product, which is why Nyxoah is challenging all three simultaneously in IPR2026-00091.
