Do You Need a Prototype Before Filing a Patent? | Protect Your Idea the Smart Way
Do you really need to build a prototype before filing your patent application?
It’s one of the most common questions inventors ask — and the answer isn’t as simple as yes or no. In this episode, attorneys Samar Shah and Jamie Brophy break down when a prototype helps, when it doesn’t, and how to file smartly without wasting time or money.
You’ll learn:
The legal truth: prototypes aren’t required — but enablement is.
How to describe your invention so others can make and use it (without building it first).
When a prototype can reveal what’s truly novel and strengthen your IP.
The risks of filing too broadly — and how it can block your own future patents.
Why a provisional application can be the best of both worlds: protection and flexibility.
How to think like an examiner and spot red flags before filing.
Why it matters:
A well-timed filing protects your idea before disclosure — but filing too early or too vaguely can cost you real protection later. This episode helps inventors and startups understand the line between an idea, an invention, and a patentable disclosure.
