When you're ready to protect an idea, one of the first forks in the road is: do it yourself, or hire a patent attorney? Both are legitimate paths. The right one depends on your budget, the complexity of your invention, and how much of the work you're comfortable owning. Here's the honest cost comparison.
The cost gap, side by side
Numbers are illustrative and vary by complexity and firm. Always check current USPTO fees.
When DIY makes sense
Filing yourself is a strong choice when you're early and budget-conscious, your invention is something you can clearly describe, and you mainly need to lock in a filing date and "patent pending" while you validate the idea. A provisional is deliberately simpler than a full patent — no formal claims required — which is exactly why so many founders file their own. Tools can carry most of the heavy lifting (structuring the description, generating figures, walking you through the portal) so "DIY" doesn't mean "alone with a blank page."
When an attorney is worth it
A patent attorney earns their fee when the stakes and complexity are high: a highly technical or crowded field, a full utility patent with formal claims that need to withstand challenge, litigation risk, or a fundraise where investors expect professionally drafted IP. Claims drafting in particular is an art — for a valuable, defensible utility patent, professional help often pays for itself.
Many founders do both — in sequence. File your own provisional cheaply to lock in the date and go "patent pending," use the 12-month window to validate the business, and then bring in an attorney for the full utility patent only if the idea proves worth the investment. You get speed and low cost up front, and expert help exactly when it matters most.
This is general information, not legal advice. Specific cases can differ.
The affordable middle path
AutoInvent sits between "totally alone" and "$15,000 lawyer." It turns your idea into structured, patent-style text and sketches and guides you step-by-step through filing your provisional yourself with the USPTO — idea to filed provisional in under 10 minutes, for a couple hundred dollars plus the USPTO fee. Lock in your date now; bring in an attorney later only if and when the idea earns it.
