The patent process
What actually happens between your idea and a granted patent.
Everything patent attorneys assume you already know — provisionals vs. non-provisionals, the 12-month clock, what an examiner actually does, and why DIY filers quietly lose their priority dates. Plain English, no legalese.
I—Step zero — the provisional
A provisional is a date stamp. Not an approval.
The single biggest misconception: provisional patents don't get approved. They don't get examined, rejected, or granted. The USPTO stamps them with a filing date and puts them in a drawer. Nobody reads them.
A sits there for 12 months and then expires. What you're actually buying with the filing date:
- A — proof you had this invention on a specific day, in writing.
- The right to say “patent pending” for 12 months.
- Time to build, test, show investors, and decide whether to pay for the real thing.
The catch
Your priority date only covers what your provisional document actually describes in detail. If your provisional says “a widget with a button” and a year later you try to claim “a widget with a button and a sensor,” the sensor part doesn't get the early date. Anything published in the meantime becomes prior art against you — for the parts your provisional didn't cover.
II—The 12-month clock
Convert, or lose it.
At month 12 your provisional expires. To keep any of that priority date you have to file a application (or a for international coverage) before the deadline. Miss it and anything you publicly disclosed in the meantime — a demo, a Kickstarter page, a product launch — becomes prior art against your own invention.
Typical timeline
Month 0
File provisional
Priority date locked. You can say “patent pending.”
Month 1–12
Build, test, refine
Anything you disclose publicly is only protected for what the provisional already described.
Month 12
File non-provisional
Examination begins. Examiner assigned, prior-art search starts.
Month 18–36
Office actions
Examiner objections. You respond. Typically 1–3 rounds.
Month 24–48
Granted — or abandoned
Patent issues if you answer the concerns. Otherwise you walk away.

III—Examination
A real person reads your non-provisional.
The non-provisional is where real examination happens. A USPTO patent examiner — an actual person with a technical degree in your field — reads your , searches the database, and writes an office action explaining what they think is wrong. You respond. They respond. Typically 1–3 rounds.
The common rejections:
§102
Anticipation
Someone already published this exact thing. One reference covers every element of your claim.
§103
Obviousness
Two or three references together make your invention the obvious next step for someone in your field. This is the hardest to overcome.
§112(a)
Written description
Your spec doesn't describe the claimed feature in enough detail for someone to actually build it. This is where bare-bones provisionals get punished.
§112(b)
Indefiniteness
Your claim uses vague language — 'about,' 'sufficient,' 'approximately' — without a clear anchor. Also includes missing antecedent basis.
IV—The trap
Why DIY provisionals quietly fail.
A DIY filer writes a 3-page description of one version of their invention. They file it, walk around saying “patent pending” for a year, and at month 12 they file the non-provisional. Then the examiner rejects their broad claims because the provisional didn't support them. The priority date is worthless for the claims that matter.
What a good provisional does differently:
- Describes multiple variants of the invention (different mechanisms, configurations, materials) so you have fallback positions when the examiner cites prior art.
- Makes sure every figure element is explained in the text — §112 written description is airtight.
- Avoids language that locks you into a narrow interpretation before the invention has even been built at full scale.
- Sometimes includes provisional claims even though they aren't required — they anchor what you consider the invention.
If you later want to claim a variant you didn't describe in the provisional, you don't get the early date for it. Over-inclusive beats over-confident.
V—What a patent attorney charges
Why the bill is $5–15K.
You're paying for 20–40 hours of drafting by someone who has written hundreds of applications. That time goes into:
- USPTO formatting — margins, line spacing, paragraph numbering.
- Legal grammar — “comprising” (open) vs. “consisting of” (closed); ; awareness.
- Broad claims with dependent fallback ladders.
- Prior art pre-search to avoid the easy §102 rejections.
Provisional (attorney)
$3,000 – $8,000
Cheaper solo firms; boutique specialists charge more.
Non-provisional (attorney)
$8,000 – $20,000
Plus $400–$1,600 in USPTO fees.
USPTO fees only (DIY)
$75 – $300
Provisional filing fee. Non-provisional adds $400–$1,600.
Office-action response
$1,000 – $3,500
Per round, typically 1–3 rounds before grant or abandonment.
VI—Where Provixer fits
What we do. And what we don't.
Provixer is a document-preparation tool, not a law firm. What we actually do:
Over-inclusive drafting, by default
Our AI drafts the spec describing multiple variants and embodiments — the same structural habit an experienced attorney uses to protect the priority date for claims you haven't written yet.
Prior-art search before you file
We search 11.4 million patents and surface what the examiner will find anyway, so you address it up front instead of getting blindsided during office actions.
Live §112 linter
Catches antecedent-basis gaps, means-plus-function triggers, and indefinite language in your claims before you file — not during examination, when fixing it costs money.
USPTO-ready export
Generated PDF and DOCX hit §1.52 formatting. Ready to upload to Patent Center.
12-month deadline tracker
We email at 90, 60, 30, 14, 7, 3, and 1 day before your conversion deadline. Missing the window is the single most expensive DIY mistake.
You own it
Your invention data is never used to train AI, never shared, never sold. Export or delete anytime.
What we don't do: freedom-to-operate opinions, examination predictions, licensing agreements, litigation strategy. Those need a licensed attorney in your jurisdiction.
VII—Decide
Provixer or attorney?
Provixer is the right fit when…
- You're a solo inventor filing your first provisional.
- You're a repeat inventor who needs ten provisionals a year instead of one.
- You have a product launch or Kickstarter coming up and need a filing date before public disclosure.
- You want a real draft — not a placeholder — without writing a $7,000 check.
Hire an attorney when…
- You're about to raise a Series A and investors want a named attorney of record.
- Your invention is in a heavily-litigated space (pharmaceuticals, semiconductor design, biotech).
- The downside cost of a bad patent exceeds the attorney fee by an order of magnitude.
- You've already received an office action and need someone to respond strategically.
Many inventors file the provisional with Provixer, then bring in an attorney to handle the non-provisional and office actions. Our upcoming Attorney Handoff package ships a clean disclosure doc, claim chart, and prior-art dossier — so the attorney isn't starting from zero.
