Provisional patent drafting · guided & AI-assisted
PatentPacket walks you through the ten questions a patent drafter would ask, assembles your answers into a USPTO-style provisional application before your eyes, and pressure-tests the draft for the gaps that sink self-filed applications. You review it. You file it. You own it.

Never done this before? Describe your idea in plain words. The guide tells you what's worth protecting, what your deadlines are, and prepares a draft — one question at a time.
Already have a product online? Paste the URL. PatentPacket reads it, flags what you've made public and your patent clock, and lists the ideas worth protecting — each one draftable in a click.
Know what you want to protect? Go straight to the ten-question studio and build a filing-ready provisional application, with the cover sheet and fee helper included.
Ten structured questions — field, problem, parts, construction, use, variations. Each comes with why-it-matters guidance, a starter template, and a worked example, so you're never staring at a blank page.
As you type, PatentPacket builds the specification live: proper section order, patent-style [0001] paragraph numbering, and automatic reference numerals for every component you list.
Run the completeness checks, export to Word, PDF, or text, and follow the step-by-step Patent Center walkthrough to file directly with the USPTO — fee from $65 as a micro entity.
Field, background, summary, brief description of drawings, detailed description, abstract — assembled in the order examiners expect, exportable to Word, PDF, and plain text.
Every component gets a patent-style numeral (100, 102, 104…) applied consistently through the document and ready to label your drawings.
The broadening and non-limiting passages professionals add by habit — inserted automatically and clearly marked for your review.
Cover-sheet checklist, current fee table, and a step-by-step Patent Center guide. You file directly with the USPTO; PatentPacket never touches your filing.
Drafts autosave in your browser and export as a project file you can reload anytime — or hand to your attorney.
Deterministic checks on every section: thin disclosure, vague wording, missing dimensions and materials, absolute language that narrows you, outcome promises that shouldn't be there. Runs entirely in your browser.
Rewrites your draft with patent-drafting conventions — permissive language, functional descriptions, precise phrasing — preserving every technical fact. You review; nothing is applied without your click.
The questions a patent drafter would ask about your section, so you can answer them before an examiner wishes you had.
A whole-application pass: where a skilled reader still couldn't build it, and where the description is narrow enough to design around. Completeness only — never a patentability opinion.
AI features run on your own Anthropic API key, stored only in your browser. No key? Everything else — interview, assembly, analyzer, exports — works fully offline.

one-time — one complete provisional patent application, start to filing-ready
One-time price for the drafting studio and your filing-ready documents. USPTO filing fees ($65 micro / $130 small / $325 undiscounted) are separate and paid by you, directly to the USPTO.
A provisional application is a written description of your invention filed with the USPTO. It is never examined and never becomes a patent by itself — its job is to establish a priority date and let you say "patent pending" for 12 months while you refine, test the market, or raise money. To keep the date, you must file a non-provisional application claiming its benefit within those 12 months. There is no such thing as a "provisional patent" — only a provisional application.
No and no. PatentPacket is a drafting tool. It gives you the structure, checks, and conventions professionals use, but it does not evaluate patentability, does not advise you, and does not create an attorney–client relationship. For anything commercially significant, have a registered patent attorney or agent review your draft — many inventors use PatentPacket precisely to arrive at that conversation prepared, which shortens the billable hours.
Because your later non-provisional can only claim the priority date for what the provisional actually discloses. A thin provisional gives you a thin priority date: anything you didn't describe — an alternative material, a variation, a dimension range — gets the later date, and intervening competitors or publications can cut it off. That's why PatentPacket pushes so hard on completeness, alternatives, and enablement.
The USPTO filing fee is $65 for micro entities, $130 for small entities, and $325 undiscounted (schedule effective January 19, 2025 — verify current fees at uspto.gov/fees). Most independent inventors qualify as micro or small entities. PatentPacket's fee guide in the studio explains the entity definitions.
They're not strictly mandatory in a provisional, but they're strongly recommended: anything a drawing shows is disclosed even if your text missed it. Clean line drawings — even careful hand sketches, one figure per page — are acceptable. PatentPacket builds your figure list and gives every component a reference numeral to label your drawings with.
Two layers. The local analyzer runs entirely in your browser — deterministic checks, nothing transmitted. The Claude-powered assists (strengthen, gap-finding, abstract, full review) run on your own Anthropic API key: the key lives only in your browser's storage, and requests go directly from your browser to Anthropic's API under your account. PatentPacket has no server and never sees your invention. Every AI suggestion is shown for your review — nothing changes your draft without your explicit click.
No — and you should be suspicious of tools that offer to. You file directly through USPTO Patent Center with the step-by-step walkthrough in the studio. That keeps your USPTO account, your receipt, and your priority date entirely in your hands.
