Dear Sir/Madam, I am the inventor and assignee of newly granted U.S. Patent US 12,612,951 B1, "Helical Tubular Compression Spring" (filed Sep 28, 2025; granted Apr 28, 2026). This architecture integrates guiding and spring functions into a single compact tube: a non‑circular guide‑rod follows a first helical path while a complementary slider bore follows a second path. A designed pitch‑length mismatch bends the guide elastically to deliver a programmable restoring force — enabling non‑linear force curves via geometry and materials. It excels in constrained recoil systems, high‑cycle actuators, and A&D/automotive mechanisms where conventional wire coils limit fatigue life and packaging. High‑spec spring/actuator segments exceed USD 30B SAM (various market reports). The claims cover the core helical mismatch, non‑circular geometry, and tuning parameters. I seek an exclusive license or joint‑development (JD) partnership with a qualified U.S. OEM for prototyping, DFM, and platform qualification. Are you available for a 20–30 minute call next week to assess roadmap fit? Under NDA, I can share CAD geometries, drawings, and theoretical F–D curves. Attached: Patent Document Copy & 10‑slide technical brief and pitch deck. Best regards,
Project ID: 40421865
