> This is NOT legal advice. Every action below needs a qualified attorney (patent, trademark, corporate, or clinical-regulatory counsel as indicated) to execute. This memo surfaces the full landscape + deadlines + costs so you can brief counsel efficiently.
---
| Protection | Urgency | Cost (one-time unless noted) | Who handles it |
|---|---|---|---|
| ESDI provisional patent | 🚨 File by May 21, 2026 (30-day window — priority-date clock ticking) | $140 USPTO + $1,500-3,000 attorney | Software/UI patent counsel (CPC G16H + G06F) |
| ESDI design patent | 🚨 Concurrent with provisional | $900-1,800 USPTO + attorney | Same counsel |
| "Silent Infinity" word-mark TM | High — file before the press release circulates | $250-350/class × 3 classes + attorney | Trademark attorney |
| Silent Infinity logo-mark TM | Medium — blocks until logo is finalized | $250-350/class × 3 classes + attorney | Same |
| Copyright registrations (key assets) | Medium — do them in batch quarterly | $65/work × ~8 works = $520 | DIY or light attorney |
| Delaware LLC or C-Corp | Depends on fundraising path | $90 LLC / $450 Corp + $800/y CA tax (if doing business here) | Corporate counsel |
| 501(c)(3) (for crisis layer — Innovation 6) | Defer until voice MVP live | ~$2-5k filing + attorney ~$3-8k | Nonprofit counsel |
| .com/.ai/.app/.wellness domains | 🟡 Audit defensive set this week | ~$50/year each | Self-serve Namecheap |
| EU trademark (EUIPO + Madrid Protocol) | Defer until 1000+ EU users | €850 EUIPO + attorney | International TM counsel |
Total realistic spend for core US protection in the next 12 months: ~$8k-15k. Most of that is patent counsel time. Without counsel: ~$3-5k minimum. Strongly recommend counsel for patents + trademarks — the self-filed failure rate is high on these.

See TOPIC-SUBTOPIC-EMOJI-PATENT-ANALYSIS-2026-04-21.docx in advisors/. Key points:
From the earlier memo. Core concept: measure voice core-vibration deviation + resistance during conversation to detect nervous-system state (parasympathetic vs sympathetic activation). Novel space — Hume AI has voice-affect patents but no vibration-resistance claim; Empatica has skin-conductance but not voice.
Our Innovation 7 — SHA-256 hashes of crisis-flagged sessions anchored to Bitcoin via OpenTimestamps for regulator / auditor verifiability.
Patentability assessment: Likely LOW. OpenTimestamps is pre-existing open-source infrastructure (Peter Todd). SHA-256 hashing is prior art. The combination of "hash user sessions + anchor to Bitcoin + publish verification endpoint" is probably obvious to a POSITA in crypto + security.
Alternative: trademark it as a METHOD + brand. Call it "Merkle-Anchored Safety Record" or similar — defend on trust/brand grounds rather than patent grounds.

Primary protection. Filed with USPTO (TEAS Plus form: $250/class; Standard: $350/class).
Classes to file in:
| Nice Class | Description | Rationale |
|---|---|---|
| Class 9 | Computer software, downloadable mobile apps | Covers the iOS/Android app when shipped, plus web-app SaaS |
| Class 42 | SaaS / cloud platforms / computer services | Covers silentinfinity.com as a service |
| Class 44 | Medical / wellness / mental health information services | Covers the wellness-chat positioning (non-medical) + transparency reports |
| (optional) Class 41 | Educational + entertainment content | If we publish essays, podcasts, courses |
Three-class filing total: $750-1,050 USPTO fees + attorney ~$1,500-3,000.
Pre-filing step (CRITICAL): Commission a full USPTO TESS + TSDR + common-law trademark clearance search by attorney. ~$400-1,200 one-time. This catches conflicts before filing. Without it: a similar mark in use elsewhere could kill the application after you've paid filing fees.
Separate application after logo is finalized (Brand Book designer-brief is the input). Same three classes. Same cost. Defer until logo is designed.
Logo-mark protects the specific visual mark (the symbol + typography lockup). Word-mark protects the words in any typography.
Per the NAME-CLEARANCE memo from Apr 19: USPTO 99340286 + 4 LLCs + iOS app already hold "Innerverse." We pivoted to Silent Infinity. Keep the trademark-search record on file forever as proof of good-faith pivot.
"A mirror for what's alive in you" + "Start anywhere" — don't file separately. Taglines are usually weak marks (descriptive). Protect them via © copyright on the marketing materials instead.
Defer until you have EU / UK / APAC users. The Madrid Protocol lets you file once at USPTO and extend to ~100 countries, but each extension costs ~$200-500 per country. At 0 foreign users today, this is premature.
Trigger to file Madrid: 1,000+ users in any single foreign country.
Starting from day 1 of silentinfinity.com launch, Silent Infinity has common-law trademark rights in the US in whatever geography we actually serve users. This is free and automatic. USPTO registration is stronger but common-law gives you standing to assert in court.
Use the ™ symbol now on all Silent Infinity branding. Switch to ® only after the USPTO registration issues (typically 9-14 months post-filing).

Copyright is automatic on creation in the US (Berne Convention). Registration is optional but gives:
| Work | Type | Why register |
|---|---|---|
| System prompt v1 (system_v1.md) | Literary work | Core IP — the voice's instruction set |
| Crisis-patterns-v1.json | Literary work / compilation | Clinical curation has real value |
| Silent Infinity Brand Book | Literary work | Marketing copy + guidelines |
| Silent Infinity Audit Document | Literary work | Comprehensive doc — investor-shared |
| Growing Tree SVG stages | Visual art | If we commission original art |
| Silent Infinity logo + glyph | Visual art | When finalized |
| Chat UI screenshots (current) | Visual art | Preserves "first publication" date for design patent support |
| /safety page content | Literary work | Compliance doc |
~8 works × $65 = $520. Batch these in one quarterly filing to save attorney time.
Once flipped to public under MIT license: no separate copyright registration needed. The MIT license itself plus git history establishes the copyright chain.
Contributor License Agreement (CLA) recommended if external contributors start submitting PRs. Use the Developer Certificate of Origin (DCO) — simple git commit -s signed-off-by pattern. Free.

You are currently a sole proprietor. All Silent Infinity contracts, AWS bills, Stripe accounts default to your personal name.
Risk: Sole-proprietor exposes personal assets to any product-liability claim. For a wellness + crisis-adjacent product, this is unacceptable beyond the pre-revenue stage.
| Option | Cost | Timeline | When to pick |
|---|---|---|---|
| Delaware LLC | $90 filing + $300/y franchise tax + $800/y CA tax if doing biz in CA | 1-2 weeks | You want simple tax pass-through, no equity compensation plans, no institutional investors |
| Delaware C-Corp | $450 filing + same taxes + stock issuance paperwork | 2-3 weeks | You plan to raise seed/VC, issue employee equity, eventually IPO |
| California LLC | $70 filing + $800/y | 2-3 weeks | Simpler if you're CA-based and not raising |
| 501(c)(3) nonprofit (Innovation 6 — crisis layer only, NOT core product) | ~$2-5k (IRS Form 1023) + state filings | 6-12 months IRS determination | Structure the crisis-detection module + research arm as a separate nonprofit |
Phase 1 (now — 3 months): Delaware LLC for Silent Infinity, S-corp taxation election. Clean pass-through for pre-revenue, liability separation, simple to upgrade.
Phase 2 (at first investor conversation): Convert Delaware LLC → Delaware C-Corp. Counsel handles the statutory conversion; 2-3 week process.
Phase 3 (post-voice MVP, demonstrable public good from crisis repo): Form a separate 501(c)(3) that OWNS the open-source crisis-detection module + collects donations. Silent Infinity Inc licenses the crisis module from the 501(c)(3) at arm's length. This is the Innovation 6 structure.

| Domain | Cost/yr | Rationale |
|---|---|---|
| silentinfinity.ai | ~$100 | AI-positioning; very low-cost insurance |
| silentinfinity.app | ~$20 | App-store adjacent, SEO value |
| silentinfinity.net | ~$12 | Cheap catch |
| silentinfinity.co | ~$30 | Common typo target |
| silentinfinity.io | ~$35 | Developer-audience SEO |
| silent-infinity.com | ~$12 | Hyphenated variant — cheap defensive |
| silentinfinity.org | ~$12 | 501(c)(3) future use |
| silentinfinity.health | ~$90 | Wellness category marker |
| silentinfinity.wellness | ~$25 | Same |
Total annual defensive-domain spend: ~$340/year. Cheap insurance. Route them all to silentinfinity.com via 301 redirects. Don't SEO them.

Lock the handle "silentinfinity" on:
Most are free, take 1-2 hours total. Do them in a single session before the press release goes public. If you don't claim them, squatters will (or have — check availability first).

6. Delaware LLC formation via Stripe Atlas ($500) or via attorney ($800-1500)?
7. Attorney engagements — want me to draft short outreach emails to 3 firms in each category (patent / trademark / corporate)?
8. 501(c)(3) — defer until voice MVP lives?
