Most founders hear a narrow script:
- file early
- get people to sign NDAs
- write a detailed spec
- build first and think about patents later if traction appears
That script is not always wrong, but it is usually too incomplete to help a founder make good decisions with limited budget and limited time. Good startup patent strategy is not a filing checklist. The real question is what deserves protection, what signal you need now, and what sequence preserves the most room to move for the least wasted effort.
Provisional Before NDA
Most founders start with secrecy. That instinct makes sense. You do not want to show the wrong person too much too early.
But the first move that usually matters is not an NDA. It is a provisional filing. Investors generally do not sign NDAs. A signature may create an expectation. A filing creates a date.
That difference matters. A priority date gives you something an NDA does not: a way to speak more freely without negotiating secrecy every time the conversation starts. It also protects against the more expensive mistake of disclosing before filing and losing foreign rights.
So the real founder question is not, "How do I make people keep this confidential?" It is, "What is the cheapest step that gives me room to talk without giving away future options?" Most of the time, the answer is file first.

Draw First. Write Second.
Founders are often told that a strong provisional starts with dense written description.
The better starting point is possession. Drawings are often the clearest way to prove what you actually had on a specific date. If prior art forces you to narrow later, a concrete original disclosure gives you more room to maneuver. A vague paragraph about a bracket gives you one path. A drawing of an L-shaped bracket with a 45-degree gusset gives you several.
That is why the sequence is simple: draw first, write second, claim third. You cannot claim more than you originally showed you had.

Build And File In Parallel
The common advice is build first and worry about patents later.
That advice only works if nothing important becomes public in the meantime. Many early teams do not have that luxury. Demos get shared. Repos get shown. Partner conversations happen before the founder feels ready.
So the question is not whether patent work should stop product work. It is whether filing work can move alongside the engineering work that is already surfacing novelty, workflow, edge cases, and diagrams. For many early teams, the answer is yes.
Capture that while you are building instead of waiting until the most important disclosure moments have already passed. By then, the cheapest useful move is often gone.
The Unifying Founder Strategy
| What founders are often told | What Andrew thinks matters more |
|---|---|
| Get an NDA signed before you talk | File first if the disclosure matters |
| Write dense legal prose first | Show possession clearly, then write to it |
| Build first, patent later | Preserve optionality while the product evidence is fresh |
| Filing volume proves strategy | The right protected leverage proves strategy |
| Patent work is a legal silo | Patent work should support founder decisions |
The goal is not to become obsessed with patents. It is to stop making early decisions from the wrong script. If the work is not increasing clarity, room to move, or bargaining power, it is probably not doing enough.
One-Paragraph Summary
Protect what changes bargaining position. File before disclosure when the conversation matters. Draw before you drown in prose. Capture the work while you are building, not after the window closes. That is startup patent strategy in founder terms.
