The Patent Timeline Problem
You’ve invented something valuable. Maybe it’s a novel manufacturing process, a software algorithm, a mechanical design, or a chemical formulation.
You know you should file a patent. But here’s the reality:
- A patent application costs $5,000-$15,000+ in legal fees
- The US Patent Office takes 20-24 months on average to process applications
- Complex patents in competitive fields can take 3-5 years
- During that entire period, your invention is unprotected against prior art claims
What happens if, 18 months into your patent process, a competitor files a similar patent? Or publishes a paper describing a suspiciously similar approach? Or claims in court that they invented the same process independently?
The answer depends on evidence. Whose documentation of the invention is more credible, and who can prove earlier dates?
Why Traditional Documentation Fails
Most inventors rely on these methods to establish their timeline:
Lab notebooks
The gold standard of invention documentation — but only if they’re properly maintained. Signature-witnessed physical notebooks carry weight, but digital lab notebooks can be accused of being backdated. Few companies maintain the discipline required.
Internal emails
“I emailed my colleague about the invention on [date]” — useful but circumstantial. Email metadata can be questioned, servers can be compromised, and the content may not fully describe the invention.
Version control (for software)
Git commits have timestamps, but the commit date can be set to any value. Without external anchoring, version control timestamps prove nothing to a third party.
Notarization
Getting documents notarized creates a legally recognized timestamp, but at $25-$150 per session. For ongoing documentation across dozens of files and iterations, it’s prohibitively expensive and logistically impractical.
Blockchain Timestamps as Prior Art Evidence
A blockchain timestamp creates a fundamentally different type of evidence:
- Your file is hashed — SHA-256 produces a unique 64-character fingerprint of your exact document
- The hash is anchored to a public blockchain — Polygon’s immutable ledger records the hash and the exact time
- Anyone can verify it — The transaction is public on Polygonscan; no trust in TimeProof required
This means:
- The contents of your document are cryptographically locked (any change produces a different hash)
- The date is recorded by a decentralized network (no single party can alter it)
- The verification is independent (works even if TimeProof doesn’t exist)
For patent purposes, this creates prior art evidence that’s stronger than internal records but much cheaper and faster than formal IP processes.
Building Your IP Protection Timeline
The most effective strategy isn’t a single timestamp — it’s a continuous timeline of your inventive process:
Phase 1: Concept
- Initial concept sketches and brainstorms
- Problem statement documents
- Prior art research notes
- First technical specifications
Phase 2: Development
- Design iterations and CAD files
- Simulation results
- Prototype photographs
- Test protocols and results
- Meeting notes with dates
Phase 3: Refinement
- Final specifications
- Performance data
- Manufacturing process documentation
- Patent draft materials
Each timestamped file becomes a node in your evidence chain. Together, they tell the story of your inventive process — a story that’s cryptographically verifiable and chronologically anchored.
Cost Comparison
| Method | Typical Cost | Speed | Independence | Tamper-Evidence |
|---|---|---|---|---|
| Blockchain timestamp (Scheduled) | 1 credit/file | Batch anchor within 6 hours | Public ledger | Cryptographic |
| Blockchain timestamp (Instant) | 2 credits/file | ~2 seconds | Public ledger | Cryptographic |
| Legal-Grade upgrade | 50 credits/batch | Added to a verified timestamp batch | Public + identity | Cryptographic + JWS |
| Notarization | $25-150/session | Appointment needed | State-recognized | Physical seal |
| Provisional patent | $320+ | 12-month window | USPTO | Federal filing |
| Full patent | $5,000-15,000+ | 2-3 years | USPTO | Federal registration |
These aren’t competing — they’re layers. Use timestamps for comprehensive ongoing documentation. Use notarization for critical milestones. Use patents for your most valuable inventions.
The Trade Secret Use Case
Not everything should be patented. Some of the world’s most valuable IP is protected as trade secrets — processes, formulas, and methods that derive value from being confidential.
Trade secrets have no registration process. The Uniform Trade Secrets Act protects them as long as:
- The information derives economic value from being secret
- The owner takes reasonable steps to maintain secrecy
But if you need to prove when you developed a trade secret — in an employee dispute, a licensing negotiation, or a theft claim — you need evidence. And most companies don’t have a good answer.
TimeProof is uniquely suited for trade secrets because:
- Your file never leaves your computer — only the SHA-256 hash is sent
- The hash can’t reveal the contents — it’s a one-way function
- The timestamp proves when — without disclosing what
Add Legal-Grade for disputes where you need to prove who had the secret, not just when it existed.
