From napkin sketch to provisional patent: a 7-day action plan
The filing process

Have a great idea but feel overwhelmed by the patent process? You don't need months of work or thousands of dollars to get to "patent pending." With a focused plan, you can go from rough concept to a filed provisional patent application (PPA) in just seven days.

Idea to "patent pending" in one week

This plan is designed for beginners and solo inventors. Each day has a clear goal and a realistic time commitment (usually 1–3 hours). By Day 7 you'll have:

The 7-day action plan

DAY1

The brain dump · ~2 hours

Goal: get your idea out of your head and into writing.

Open a blank document and write without worrying about structure. Answer: What problem does this solve? Who's it for? How does it work? What are the main parts or steps? Sketch rough drawings on paper — even boxes and arrows are fine. Don't edit yet; just capture everything.

DAY2

Structure and detail · ~3 hours

Goal: turn messy notes into a structured description.

Create headings like Background / Problem, Summary of the Invention, Detailed Description, and How It Works / Use Cases. Rewrite your Day 1 notes under them. Start numbering parts on your sketches (100, 110, 120) and refer to them in your text: "As shown in FIG. 1, handle (100) connects to…" It's starting to look like a real patent-style document.

DAY3

Prior art search · ~2 hours

Goal: see what's already out there and clarify what makes your idea different.

Search keywords related to your invention on Google Patents. Skim a handful of similar patents or published applications and ask: What looks similar? What do they do differently? Update your description to highlight what's new and better. This isn't a full legal search, but it helps you position your idea and avoid reinventing what already exists.

DAY4

Refine and expand · ~2 hours

Goal: make your description as complete as possible.

Think about variations: Could it use different materials? Could a part be a different shape, size, or configuration? Are there multiple ways to achieve the same result? Add an "Alternative Embodiments" or "Variations" section describing these. This broadens your potential protection and makes your provisional more robust.

DAY5

Create patent-style sketches · ~1 hour

Goal: turn rough sketches into cleaner, patent-style drawings.

Use AI tools or simple digital drawing tools to create front, side, and perspective views. Add clear outlines and consistent line weights, and place reference numbers that match your written description. At minimum, have one main view showing the invention, plus additional views for important features. They don't need to be perfect — just clear, consistent, and readable.

DAY6

Final review and assembly · ~1 hour

Goal: assemble a single, complete provisional package.

Combine your written description and drawings into one document (often a PDF). Read through once more: Does it explain how to make and use your invention? Do figure numbers and reference numbers match the text? Are there gaps or obvious open questions? Fix minor typos and clarity issues. You should now have a provisional-ready spec with drawings.

DAY7

File your provisional patent · ~1 hour

Goal: file your PPA with the USPTO and become "patent pending."

Create or log into a USPTO Patent Center account. Fill out the provisional cover sheet (e.g. USPTO Form SB/16). Upload your description and drawings (usually a PDF). Pay the provisional filing fee (often around $65 for micro entities; check current USPTO fees). Save your confirmation number, application number, and filing date. Once filed correctly, you can typically say your invention is "patent pending." For a full walkthrough of this step, see our guide on how to file a provisional patent.

Where AutoInvent fits in

From 7 days to 10 minutes

This plan is perfect if you want to learn the process by hand. But if you'd rather compress it into a single guided flow, AutoInvent turns your idea into patent-style text and structured sections in minutes, helps you generate patent-style sketches that match, and walks 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. You stay the inventor and applicant; AutoInvent just takes the overwhelm out of getting to "patent pending."
