Solo Founder Uses Claude Code for FDA Submission and Patent Review

A solo founder building a contactless sleep monitor (hardware, firmware, cloud, and app) documented a 10-hour Claude Code session that handled complex regulatory and legal work typically requiring specialized teams.
What Got Done in One Session
- FDA Pre-Submission filing: Claude walked through every field on the electronic form, indicated which dropdowns to select, and identified the user was on the wrong FDA portal before they wasted time registering for something not yet needed.
- 8 FDA regulatory documents created from scratch: Not templates with TODOs, but actual content pulled from existing docs and cross-referenced for consistency. Documents included cover letter, device summary, indications for use, EMC testing plan, and declarations of conformity.
- Patent review via parallel agents: Launched 4 parallel agents pretending to be different experts (RF engineer, sleep medicine doctor, patent attorney, business strategist). They independently reviewed the patent and returned 96 novel ideas while finding 14 vulnerabilities in existing claims. One agent discovered that 10 methods described in the patent were never formally claimed.
- 38 regulatory document references updated: FDA changed their quality system regulation earlier this year and reissued cybersecurity guidance. Claude handled finding and updating all references that would have taken days manually.
- Additional tasks: Built system architecture diagrams, converted everything to PDF, created consent forms for a data collection study, and deployed UI changes to a Raspberry Pi device at midnight to add blanket type tracking to calibration protocol.
User Context and Approach
The founder is a software engineer with ~26 years as a CTO experience, not a regulatory expert or patent attorney. They describe Claude Code as "letting me operate like a 10-person team" where the FDA submission alone would have cost thousands with a consultant and taken weeks, but was completed in an afternoon.
The founder emphasizes that Claude taught them FDA submissions and patent law in real time during the session. They bring domain expertise in knowing when to push back, what questions to ask, what good architecture looks like, and the sleep industry well enough to come up with novel concepts. As they put it: "The AI doesn't replace expertise - it replaces the 10 specialists you can't afford to hire. But you still need to be the person in the room who knows what to build and why."
One specific example highlighted was Claude telling them to STOP trying to register for FDA establishment registration because it wasn't needed yet and would have cost thousands unnecessarily.
