Patent filing services covers businesses that do very different things, and the label does not distinguish them.
Only two categories can represent you before the USPTO — registered patent attorneys and registered patent agents.
Everyone else is doing something adjacent. That may be legitimate and useful; it is not representation.
And the thing that separates good outcomes from bad ones is claim drafting, which is also the thing hardest to judge before you have the result.
The categories
| Provider | Can represent you? | Typically does |
|---|---|---|
| Registered patent attorney | Yes | Drafts, prosecutes, opinions, litigation |
| Registered patent agent | Yes | Drafts, prosecutes |
| Online platform with affiliated practitioners | Through them | Varies — ask who drafts |
| Form-filling service | No | Paperwork, formatting |
| Search firm | No | Prior art searching |
| Draftsperson | No | Drawings |
| Invention promoter | No | Evaluation and submission packages |
Agents and attorneys hold the same USPTO registration. The attorney premium buys litigation and opinion capability you may not need. See patent attorneys.
What actually needs a registered practitioner
| Task | Registration required |
|---|---|
| Drafting claims on your behalf | Yes, to represent you |
| Prosecuting before the USPTO | Yes |
| Filing for yourself | No — pro se is permitted |
| Prior art searching | No |
| Preparing drawings | No |
| Translations | No |
| Annuity payment | No |
Pro se filing is legal. Thousands do it, and the risk is not rejection — it is a patent whose claims are too narrow for anyone to want.
What you can do yourself for free
| Task | Tool |
|---|---|
| Prior art search | Google Patents, Patent Public Search, Espacenet |
| Entity status check | The criteria |
| Reading competitor filings | Patent Center |
| Deadline tracking | A calendar |
| Listing every variation | Your own knowledge |
Arriving with a search and a variation list makes any engagement cheaper, because the practitioner spends time drafting rather than extracting.
What separates providers
| Factor | Weight |
|---|---|
| Claim drafting quality | Highest |
| Alternatives described | High |
| Prosecution judgement | High |
| Turnaround | Low |
| Headline price | Misleading alone |
Costs
| Item | Typical |
|---|---|
| Provisional drafting | $1,500–$4,000 |
| Non-provisional drafting | $5,000–$15,000 |
| Office action response | $1,200–$4,000 each |
| Continuation | $3,000–$6,000 |
| Professional search | $500–$3,000 |
| USPTO fees | Large | Small (40%) | Micro (20%) |
|---|---|---|---|
| Filing, search, examination | ~$2,000 | ~$800 | ~$400 |
| Issue fee | ~$1,200 | ~$480 | ~$240 |
| Maintenance, lifetime | $14,470 | $5,788 | $2,894 |
Official fees scale with entity status; professional fees do not. Micro entity status cuts USPTO fees by 80% and changes nothing about drafting cost. See small entity status.
A quoted total far below the drafting range usually means claims are not being professionally drafted. That is the thing you are actually buying.
What a good engagement letter covers
| Term | Detail |
|---|---|
| Scope | Exactly what is drafted and filed |
| Who does the work | Named, with registration number |
| Fees | Fixed or hourly, and for what |
| Office actions | Included or extra, and at what rate |
| Timeline | Drafting turnaround |
| Confidentiality | Before any disclosure |
Questions before hiring
| Ask | Weak answer |
|---|---|
| Who drafts the claims, and are they registered? | No name given |
| Their registration number | Evasion |
| Experience in this technology | "We cover everything" |
| What is included, what is extra | "It depends" |
| What happens at an office action? | Not addressed in the quote |
| Turnaround for drafting | "A few days" on a complex invention |
| Can I see a sample application? | No |
| How are foreign associate fees billed? | Unclear |
Registration numbers are public and verifiable. Asking for one is normal, and reluctance is informative.
Office action responses are where budgets overrun. A quote covering only drafting and filing describes maybe half the real cost.
What is usually included and what is not
| Item | Often included | Often extra |
|---|---|---|
| Drafting the specification | Yes | — |
| Claims | Yes, if a practitioner drafts | — |
| Drawings | Sometimes | Frequently extra |
| Filing and forms | Yes | — |
| Prior art search | Frequently not | Yes |
| Office action responses | Usually not | Yes — the budget overrun |
| Continuations | No | Yes |
| Foreign filings | No | Yes, plus associate fees |
Office action responses are where quotes diverge from reality. Most applications draw at least one rejection, so a quote covering only drafting and filing describes roughly half the true cost.
Distinguishing an invention promoter
Federal law requires invention promoters to disclose under 35 U.S.C. §297, in writing, before you contract:
- Total customers in the past five years
- How many received a net financial profit
- How many obtained licence agreements
- Any other trading names
| Red flag | Meaning |
|---|---|
| They contacted you first | Enthusiasm preceded evaluation |
| Paid evaluation returns positive | Positive evaluations are the product |
| Will not give §297 numbers | The numbers are bad |
| Guaranteed outcomes | Nobody can guarantee a grant |
| Pressure to decide today | Filing deadlines are real; sales deadlines are not |
| No named registered practitioner | Nobody accountable is drafting |
| Rights transferred to them | Never sign this |
Read the net-profit figure, not the customer count. See invention companies.
Verifying a practitioner
| Check | How |
|---|---|
| USPTO registration | Public register, searchable |
| Registration number | Ask for it |
| Attorney or agent | Register states which |
| Bar admission, if claimed | State bar records |
| Disciplinary history | Public |
| Technical background | Agents and attorneys need a technical qualification |
Registration is public and free to verify. A practitioner who cannot or will not supply a number has answered the question.
Pro se is a real option
| Legally permitted | Yes |
| USPTO Pro Se Assistance Program | Free guidance |
| Risk | Claims too narrow to be worth anything |
| Suits | Simple mechanical inventions, low stakes |
Turnaround is a signal
| Task | Reasonable |
|---|---|
| Prior art search | Days to weeks |
| Provisional drafting | 1–3 weeks |
| Non-provisional drafting | 2–6 weeks |
| Office action response | 2–4 weeks |
| Same-week non-provisional | Warning sign |
Proper drafting requires understanding the invention and systematically describing alternatives, ranges and embodiments. That takes time and it is where the value is.
Scope creep in engagements
| Item | Frequently extra |
|---|---|
| Office action responses | The main one |
| Drawings | Often |
| Prior art search | Often |
| Continuations | Yes |
| Foreign coordination | Yes, plus associate fees |
| Expedited handling | Yes |
Agree what happens at the first office action before signing, since most applications draw one.
What good drafting produces
| Feature | Why it matters |
|---|---|
| Several described embodiments | Amendment room when art appears |
| Nested ranges | Retreat positions |
| Independent claims at three breadths | Fallbacks |
| Method and apparatus claims | Reach different infringers |
| Technical framing in the background | Avoids §101 signals |
| Consistent reference numerals | Fewer objections |
Nothing can be added after filing. Each row above either exists on the filing date or is permanently unavailable. See how to write a patent application.
Sample requests
| Ask for | Shows |
|---|---|
| A granted patent they drafted | Claim quality |
| Its file history | How they handled rejections |
| Something in your field | Technical fit |
The file history is more revealing than the patent. It shows whether they argued or simply narrowed at every step.
Overseas providers
| Consideration | Detail |
|---|---|
| Drafting support | Common, cost differs substantially |
| Representation before the USPTO | Registered practitioner required |
| Confidentiality | NDA before disclosure |
| Export considerations | Some technologies restricted |
| Foreign filing licence | May be required before filing abroad first |
| Quality variation | Wide — ask for samples |
A foreign filing licence issue arises where an invention made in the US is filed abroad first. The filing receipt normally grants it; check before filing elsewhere.
After filing, what continues
| Item | Who |
|---|---|
| Office action responses | Usually the same provider, billed separately |
| Continuation decisions | Yours, on their advice |
| Maintenance fees | Yours — an annuity service or a calendar |
| Foreign filings | Coordinated through associates |
| Entity status | Yours to re-verify |
Maintenance is not usually part of a filing engagement. Someone has to own those three deadlines, and by default nobody does. See patent maintenance.
Worked example: three quotes
Same invention, three providers.
| Quote A | Quote B | Quote C | |
|---|---|---|---|
| Headline price | $650 | $7,200 | $14,500 |
| Who drafts claims | Not stated | Registered agent, named | Attorney, named |
| Office actions | Not included | 2 included | 2 included |
| Search | No | Yes | Yes |
| Turnaround | 3 days | 3 weeks | 4 weeks |
| Sample available | No | Yes | Yes |
What the $650 buys
| Likely deliverable | Formatting of your own text |
| Claims | Probably yours, unreviewed |
| Office actions | Billed separately, or you handle them |
| Real total if it draws two rejections | Far above $650 |
Quote A is not necessarily dishonest. It may be exactly what it says — a filing service, not a drafting service. The problem is the headline invites comparison with quotes that include the thing that matters.
Quote B captures most of the value at half Quote C's cost, which is the usual position where litigation is not anticipated.
Working well with a practitioner
| Practice | Why |
|---|---|
| Bring your prior art search | Saves their time, and yours |
| List every variation you can think of | They cannot invent alternatives for you |
| Explain the commercial context | Shapes claim strategy |
| Identify what competitors do | The claims should reach it |
| Respond to drafts properly | You know the technology |
| Flag any disclosure or sale dates | Deadlines depend on them |
Disclosure dates matter more than clients realise. A trade show six months ago changes the entire foreign filing analysis, and a practitioner cannot know it unless told.
Before hiring anyone
| Step | Cost |
|---|---|
| Free prior art search | $0 |
| Read the close references | $0 |
| Check micro entity eligibility | $0 |
| Apply to a law school IP clinic | $0 |
| Write down every variation you can think of | $0 |
Law school clinics do real work under the USPTO's Law School Clinic Certification Program, supervised and free for qualifying applicants.
The free search makes every later conversation better, because you arrive knowing whether the idea is new. See patent an idea free.
Red flags in any quote
| Signal | Meaning |
|---|---|
| No named registered practitioner | Nobody accountable is drafting |
| Guaranteed grant | Nobody can guarantee examination outcomes |
| Same-week turnaround on a complex invention | Not being drafted properly |
| Price far below the drafting range | Scope is narrower than it appears |
| Office actions not mentioned | Budget will overrun |
| Rights assigned to the provider | Never acceptable |
| No sample available | Nothing to assess |
Guaranteed outcomes is the clearest signal. Examination is uncertain and anyone promising otherwise is selling something else.
What most filings become
| Ipiry Patent Survival Curve v1.0 | Rate |
|---|---|
| Survive the 3.5-year fee (2022 cohort) | 85.8% |
| Survive the 7.5-year fee (2018 cohort) | 64.6% |
| Reach full term (2014 cohort) | 41.4% |
| Abandoned before full term | 58.6% |
Computed from 27,273,654 USPTO maintenance fee records covering 8,262,336 US utility patents — see the patent survival curve.
Nearly three in five granted patents are released early. Spending well on drafting is what makes a patent worth keeping or worth selling; spending badly produces one that joins that statistic.
Foreign associates
| Point | Detail |
|---|---|
| Required | In most countries, a local representative |
| Billed | Passed through, sometimes marked up |
| Ask | Whether fees are marked up, and by how much |
| Choice | Whether you can nominate your own |
| Translation | Frequently arranged through them |
Associate fees are a real part of foreign filing cost and worth understanding before committing to jurisdictions.
Patent filing services: the checklist
- Only registered attorneys and agents can represent you. Verify registration.
- Ask who drafts the claims, by name.
- Use an agent rather than an attorney where litigation is not anticipated.
- Compare what is included, especially office action responses.
- Treat a very low headline price as a scope question, not a bargain.
- Demand the §297 disclosure from anyone selling evaluation or submission.
- Never transfer rights to a provider you are paying.
- Expect weeks, not days, for proper drafting.
- Run the free search and check entity status yourself first.
- Never economise on claim drafting. It determines what you own, permanently.
