Most inventors get the timing wrong — they wait until they can afford a patent before protecting their idea. By then, it's often too late.
Here's what to do instead, starting today.
The danger window: The period between having an idea and filing a patent is when most invention theft happens. Competitors, contractors, co-founders, and even investors have been known to use information shared during this phase.
Method 1: Blockchain timestamp (proof of existence)
Cost: $5 | Time: 2 minutes | Best for: All stages
Create a detailed written description of your invention — what it does, how it works, what problem it solves. Then timestamp that document on a blockchain.
The blockchain creates an immutable record that this document existed at this exact moment. Crucially, the document itself is never uploaded — only its cryptographic hash. No one can read your invention from the blockchain.
What it protects: Establishes prior art, supports trade secret claims, creates evidence for any future dispute about who had the idea first.

Method 2: Non-Disclosure Agreement (NDA)
Cost: $0–$500 | Time: Hours to days | Best for: Sharing with others
Before sharing your idea with anyone — investors, potential co-founders, contractors, employees — get a signed NDA. An NDA creates a legal obligation of confidentiality and gives you grounds to sue if they disclose or use your information.
Important: An NDA alone is weak without timestamps. If someone breaches it, you need to prove what was disclosed and when. Combine NDA with a blockchain timestamp for maximum protection.
Method 3: Provisional patent application
Cost: $320–$1,600 | Time: Weeks | Best for: Pre-commercialization
A provisional patent application gives you "patent pending" status for 12 months at a lower cost than a full patent. It establishes a priority date and lets you publicly disclose the invention during those 12 months without losing patent rights.
What it protects: Creates an official USPTO priority date. Buys you 12 months to raise funding, find partners, or validate the market.
Method 4: Trade secret protection
Cost: Variable | Time: Ongoing | Best for: Ideas you won't patent
If you don't intend to patent (because you want to keep the method secret), treat the invention as a trade secret. This means strict access controls, NDAs for everyone with access, and documented security measures.
Key requirement: To claim trade secret protection, you must demonstrate you took reasonable steps to keep it secret. Blockchain timestamps + NDAs + access logs are your evidence.
Method 5: Defensive publication
Cost: $0 | Time: Hours | Best for: Open-source, defensive strategies
If you don't want a patent, publish a description of the invention publicly. Once published, it becomes prior art that prevents anyone else from patenting it.
Warning: Once published, you lose the ability to patent it yourself. Only use this if you're sure you don't want a patent.
Recommended protection stack
| Timing | Action |
|---|---|
| Day 1 | Blockchain timestamp your invention document ($5, 2 min) |
| Before sharing | Get signed NDAs from everyone who sees the idea |
| Month 1–3 | Continue timestamping as the invention evolves |
| Month 3–6 | File a provisional patent ($320–$1,600) if commercializing |
| Month 6–18 | File a full patent application with attorney support |
Start with the easiest step
The blockchain timestamp is the easiest, cheapest, and fastest first step. It takes 2 minutes and costs $5. Even if you do nothing else from this list, a timestamp before your first disclosure is invaluable protection.
