China Cross-Border Tech Lawyer: Evaluate JV Proposal, Structure IP Safeguards & NNN Agreements

Background: I have a working prototype and a pending China patent (filed 3 years ago, awaiting approval). A large Chinese manufacturer has proposed a joint venture-they finance prototype development, I contribute the technology and know-how. My Question: Is the JV the best structure, or is there a safer, smarter alternative? What I Need Evaluate the JV: Pros/cons vs. 2–3 alternatives (licensing, phased partnership, tech transfer with royalty, etc.) Structure the deal: Ensure I retain core IP ownership, control over derivatives, audit rights, and a clean exit path Required 7+ years structuring China cross-border manufacturing/tech deals Deep experience protecting foreign IP holders in Chinese partnerships Access to China-qualified local counsel Apply If: You have worked with Real-world JV ownership splits in China tech/manufacturing deals and you know what's typical, what foreign IP holders actually negotiate, and where the leverage points are. You know tax implications for a Hong Kong-incorporated company entering a China JV or alternative structure (withholding, repatriation, treaty benefits, and optimal holding structures) You know how to preserve my right to license or sell this invention for other products/applications outside the JV's scope—field-of-use restrictions, carve-outs, and non-exclusive licensing frameworks that actually hold up in practice No generic theoretical answers. I've already read the basics. I need judgment forged from deals you've personally done or advised on in this exact space.
