Provisional application

File a provisional patent application.

Professional fees. Government fees not included.

Secure an early filing date—and get “patent pending” status for 12 months.

A provisional application is a lower-cost first step toward a patent. It establishes an early filing date for the invention it describes and lets you use “patent pending” while you develop your product, test customer interest, or seek funding.

It gives you up to 12 months to decide whether to pursue a full utility patent application—and prepare for that larger investment.

An inquiry does not create an attorney-client relationship or accept a deadline.

Choose the support that suits you.

Choose the level of help you need: filing an application you have prepared, having a patent attorney review it and then file it, or having a patent attorney prepare and file it for you.

Looking ahead

What comes next?

A provisional normally lasts 12 months. The closing information identifies your next filing deadline and who will receive patent-office correspondence. A later application and ongoing deadline monitoring require a separate agreed scope.

Service fit, conflicts, scope, and engagement are handled personally before substantive work begins.

Questions about this service.

Can I hire you just to file a provisional application I wrote myself?

Yes—our Filing Only package files a provisional application you prepared for a $249 professional fee, plus $65 in government fees at filing if you qualify as a micro entity. You provide the description and drawings, and we handle the attorney-supervised submission, filing confirmation, and copies of your filed documents. It covers applications up to 100 pages and does not include drafting, a patentability opinion, or a full assessment of whether your disclosure is legally adequate.

Can you review and file a provisional application I wrote myself?

Yes—our Review & file package covers a self-drafted provisional application for a $699 professional fee, plus $65 in government fees at filing if you qualify as a micro entity. We review your application for one invention, up to 40 pages and 10 drawing sheets, and send you a written list of gaps in how it describes the features you tell us matter. You make the changes, we recheck them once, and we file after your approval. It does not include rewriting, claim drafting, a prior-art search, or a patentability opinion. We quote longer applications before you engage.

What do you check before filing a provisional application I prepared?

With Filing Only ($249), we review your prepared description, drawings, and filing information administratively and tell you about any obvious missing information before submission. We don’t draft or rewrite your application or fully assess whether the disclosure is legally adequate, and material gaps may require a different service before filing. With Review & file ($699), we also review how your application describes the features you tell us matter and send you a written list of gaps before filing. Our Draft & file ($1,099) and Draft, discuss & file ($1,399) packages go further: we prepare the application from your materials and review it substantively, aiming to give your invention the fullest written description support we can.

How much does a provisional patent application cost in total?

Our professional fee is $249 to file an application you prepared (Filing Only), $699 to review an application you prepared, list any gaps, and file it (Review & file), $1,099 for attorney drafting and filing with email support (Draft & file), or $1,399 for drafting and filing with two focused calls (Draft, discuss & file). Government fees at filing are $65 if you qualify as a micro entity. The later nonprovisional application is a separate stage with its own work and fees.

Who writes my application?

With Filing only and Review & file, you provide the description and drawings and we handle the agreed review and filing work. With Draft & file and Draft, discuss & file, we prepare the application from your materials, review it, and file after your approval.

Does a provisional become a patent?

No. It is not examined and does not itself become a patent. A later application is a separate stage with its own work and fees.

What does an early filing date cover?

Only subject matter adequately supported by the provisional application. Filing is not a guarantee of patent protection.

Can I change the invention during drafting?

The package covers the invention agreed before engagement and one consolidated revision. Additional inventions or substantial new work need a separate agreed quote. Ordinary underestimation of the agreed work remains our responsibility.
