Patent services divide into categories that look adjacent and are not.
Only two require a registered practitioner — drafting and prosecuting applications before the USPTO.
Everything else is open, which is why the market is fragmented and why comparing a search quote against a drafting quote tells you nothing.
And several of them you can do yourself for free, which is worth knowing before commissioning anything.
The categories
| Service | Registration required? | Typical provider |
|---|---|---|
| Prior art search | No | Search firms, some agents |
| Drafting | Yes | Attorney or agent |
| Prosecution | Yes | Attorney or agent |
| Annuity payment | No | Annuity services |
| Portfolio monitoring | No | Software and services |
| Valuation | No | Specialists, accountants |
| Brokerage | No | Brokers |
| Claim charting / EoU | No | Specialists, counsel |
| Litigation | Bar admission | Attorneys only |
| Drawings | No | Draftspersons |
| Translation | No | Specialist translators |
Agents and attorneys hold the same USPTO registration. An attorney is additionally admitted to a bar, which is what enables opinions and litigation.
For drafting and prosecution where litigation is not anticipated, an agent does the same work for less. See patent attorneys.
Searching
| Type | Purpose |
|---|---|
| Patentability / novelty | Before filing |
| Freedom to operate | Before launching a product |
| Invalidity | Against a specific patent |
| State of the art | Landscape understanding |
| Evidence of use | Finding infringers of your own patent |
These are different searches with different outputs. A patentability search looks for anything disclosing your invention; an FTO search looks for in-force claims your product would infringe.
Do the free version first. Google Patents, USPTO Patent Public Search and Espacenet cost nothing and eliminate most inventions. See patentability search services.
Drafting and prosecution
| Item | Typical range |
|---|---|
| Provisional | $1,500–$4,000 |
| Non-provisional drafting | $5,000–$15,000 |
| Office action response | $1,200–$4,000 each |
| Continuation | $3,000–$6,000 |
| Appeal brief | Substantial |
| 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.
Drafting is the one not to cut. It determines what you own and cannot be fixed afterwards.
Annuity and maintenance services
| Service | Detail |
|---|---|
| Deadline tracking | Across jurisdictions |
| Payment execution | Official fees paid |
| Currency handling | Conversion and remittance |
| Fee forecasting | Budgeting across years |
| Insurance | Covers their error, not your late instruction |
Needed for any foreign portfolio. Foreign annuities fall due annually per country, and a four-country family generates roughly twenty deadlines a year.
Verify payments in Patent Center, not against provider confirmations. See patent annuity payment services.
Monitoring and watch services
| Watch | Purpose |
|---|---|
| Competitor filings | New grants and published continuations |
| Litigation dockets | Cases naming you or competitors |
| Assignment records | Transfers into assertion entities |
| Classification alerts | New art in your field |
| Own fee deadlines | The backstop |
Most of this can be done free. Docket alerts, assignment searching and classification alerts cost nothing, and commercial tools earn their price at scale rather than at small portfolios. See patent litigation updates.
Valuation
| Provider | Typical use |
|---|---|
| Specialist IP valuation firms | Transactions, financing |
| Accounting firms | Tax and reporting |
| Some brokers | Pre-sale indication |
| Expert witnesses | Litigation |
Ask what assumptions were used. Royalty rate, revenue base, discount rate and useful life drive the answer, and a valuation not stating them cannot be checked.
Note what data does not exist. No public dataset contains comprehensive patent sale prices, so market comparisons are harder than in most asset classes. Academic datasets provide patent value estimates rather than transaction records. See intellectual property valuation.
Brokerage
| Model | You pay |
|---|---|
| Contingency | Nothing upfront, % of sale |
| Retainer plus success fee | Both |
| Fee-for-service | Fixed fees regardless of outcome |
Contingency brokers select hard, since unpaid effort on an unsaleable asset is a loss. A decline is free diagnostic information.
Maintenance fees stay with you throughout a sale process. See patent brokers without upfront fees.
Claim charting and evidence of use
| Service | Output |
|---|---|
| Infringement charts | Claims mapped to products, with cited evidence |
| Invalidity charts | Claims mapped to prior art |
| Product teardowns | Physical verification |
| Technical analysis | Expert assessment |
This is the service most directly connected to value. A patent with a documented chart against a shipping product is a different asset from one without.
Verify every citation in a delivered chart. A fabricated or misread source is worse than an empty row. See claim chart example.
What you can do free
| Task | Tool | Time |
|---|---|---|
| Check in-force status | USPTO Patent Center | 3 min |
| Check current ownership | USPTO Assignment Search | 5 min |
| Calculate remaining term | Front page + PTA | 5 min |
| Prior art screening | Google Patents, Espacenet | Hours |
| Screen for products practising your claims | Product docs, competitor filings | Hours |
| Track US fee deadlines | A calendar | Ongoing |
Providers will charge for all of these. Doing them first also makes any paid engagement more productive, because you arrive knowing what the questions are.
Worked example: three budgets
One invention, three service configurations.
| Minimal | Balanced | Full | |
|---|---|---|---|
| Free search | $0 | $0 | $0 |
| Professional search | — | $1,500 | $3,000 |
| Provisional | Self-drafted | Agent, $1,800 | Attorney, $2,500 |
| Non-provisional | Self-drafted | Agent, $6,500 | Attorney, $9,000 |
| Prosecution (2 rounds) | Self | $4,800 | $6,400 |
| Annuity service | — | — | Yes |
| EoU chart before sale | — | Self-produced | $3,000+ |
| To grant (micro entity fees) | ~$700 | ~$15,300 | ~$21,300 |
What each likely produces
| Minimal | Balanced | Full | |
|---|---|---|---|
| Grant | Possible | Likely | Likely |
| Claim breadth | Usually narrow | Good | Good |
| Amendment room | Limited | Yes | Yes |
| Saleable later | Uncertain | Yes | Yes |
The balanced column captures most of the value at two thirds of the full cost, and for an inventor not anticipating litigation it is frequently the right answer.
The minimal column's risk is not failing to get a patent. It is getting one whose claims are too narrow for anyone to want.
Foreign filing services
| Service | Detail |
|---|---|
| PCT filing and national stage | Defers country decisions to ~30 months |
| Foreign associates | Required in most jurisdictions |
| Translation for national stage | Substantial cost |
| Foreign annuities | Annual, per country |
Foreign associates are unavoidable in most jurisdictions, and their fees pass through whoever coordinates the filing. Ask how they are billed.
Litigation support
| Service | Who provides it |
|---|---|
| Litigation counsel | Attorneys, bar admitted |
| PTAB proceedings | Registered attorneys |
| Expert witnesses | Technical specialists |
| Damages experts | Economists, accountants |
| Document review | Support providers |
| Opinions of counsel | Attorneys only |
Opinions of counsel are the willfulness defence and must come from an attorney, before the conduct rather than after suit. See willful infringement.
Red flags across every category
| Signal | Meaning |
|---|---|
| They contacted you first | Enthusiasm preceded evaluation |
| Guaranteed outcomes | Nobody can guarantee a grant or a sale |
| Pressure to decide today | Filing deadlines are real; sales deadlines are not |
| Large upfront fee for submission | The fee is the business |
| No named registered practitioner for drafting | Nobody accountable |
| Will not put scope in writing | Disputes later |
Guaranteed outcomes are the clearest signal. Examination outcomes and sale outcomes are both uncertain, and anyone promising otherwise is selling something else.
Choosing a provider
| Ask | Weak answer |
|---|---|
| What exactly is the deliverable? | Vague |
| What is included and what is extra? | "It depends" |
| Are you registered (drafting/prosecution)? | Evasive |
| Comparable work in this technology? | No examples |
| Who does the actual work? | Unclear |
| How is confidential information handled? | No NDA |
| What happens if I am not satisfied? | No answer |
Ask who does the work, not who sells it. Delegation is normal and worth knowing about.
What to keep in-house
| Task | Why |
|---|---|
| The renewal decision | Commercial judgement |
| Entity status determination | Depends on your circumstances |
| An independent deadline record | Outsourcing execution is not outsourcing consequence |
| Verification against office records | Minutes, catches everything |
Entity status is the trap. A service applies the status you give it, and paying at a reduced rate when no longer entitled can render a patent unenforceable. See small entity status.
Drawings and translation
| Service | When needed |
|---|---|
| Formal drawings | Before issue; informal accepted at filing |
| Design patent drawings | The drawings are the claim |
| Certified translation | Foreign art in proceedings |
| Machine translation | Screening only |
| Foreign filing translation | National stage entry |
Design drawings are claim drafting, not illustration. Solid lines claim; broken lines disclaim, and a line-type error changes scope. See patent drawing.
Where most spending is wasted
| Waste | Why |
|---|---|
| Skipping the free search | Costs nothing, eliminates most inventions |
| Cutting drafting cost | The one thing that cannot be fixed later |
| Paying fees by default | 58.6% of patents are eventually abandoned |
| Filing broadly abroad without revenue there | Annual escalating cost |
| Commissioning valuation before checking status | The patent may be dead |
| 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.
Paying by default is the largest silent cost. Every fee window is a four-way decision, and two of the options happen by not acting.
Patent services: the checklist
- Know which category you are buying. Quotes are not comparable across them.
- Only drafting and prosecution need a registered practitioner.
- Use an agent rather than an attorney where litigation is not anticipated.
- Run the free search first. It is the highest-value step and costs nothing.
- Never cut drafting cost. It sets the ceiling on everything downstream.
- Use an annuity service for any foreign portfolio.
- Ask what assumptions any valuation used, or it cannot be checked.
- Check status and ownership yourself before commissioning anything.
- Keep the renewal decision and entity status in-house.
- Treat every fee window as a decision, not an invoice.
