Many startups begin with a provisional application, a lower-cost filing that holds a filing date for 12 months; keeping that date requires filing a non-provisional, or utility, application within that year. Public disclosure before filing is one of the most common avoidable mistakes: the United States provides a one-year grace period for inventors’ own disclosures, but many other countries do not. USPTO fee reductions are 60% for small entities and 80% for micro entities, effective December 29, 2022, under the Unleashing American Innovators Act. A USPTO-registered patent attorney or agent should draft the claims—the statements defining the protection requested.
Provisional vs non-provisional applications
A provisional establishes an early filing date for the invention it adequately describes. A non-provisional seeks an enforceable patent through examination by the United States Patent and Trademark Office, or USPTO.
| Feature | Provisional | Non-provisional (utility) |
|---|---|---|
| What it does | Establishes a filing date for adequately described subject matter | Requests examination and patent protection |
| Examined by the USPTO | No | Yes |
| Claims required | No | Yes |
| How long it lasts | 12 months | Examination time varies; any resulting patent has a separate term |
| Can it become a patent by itself | No | Can result in a patent if allowed |
| Government filing fee in 2026 | Undiscounted / small / micro: $325 / $130 / $65 | Filing, search and examination, filed electronically: $2,000 / $730 / $400 |
| Patent term effect | Provisional year does not count toward the term | Generally 20 years from earliest relied-upon non-provisional filing |
A provisional is only as useful as its description; a thin filing may fail to support later claims. File a complete description, including relevant drawings and implementation details, with a registered practitioner’s help.
The filing-date rule comes from 35 U.S.C. § 119(e); the general utility patent term comes from 35 U.S.C. § 154. The table uses the USPTO fee schedule effective January 19, 2025, last revised November 1, 2026.
The 12-month clock and what counts as disclosure
Track the provisional deadline separately from publication plans. The later application must claim the provisional’s filing date, with adequate support for the claimed invention.
Under 35 U.S.C. § 102(b)(1), an inventor’s disclosure—or one by someone who obtained the information from the inventor—one year or less before the effective filing date is excluded from prior art against those claims. Prior art means earlier information used to assess patentability. Many other countries require absolute novelty: public disclosure before filing can prevent patent protection there.
Potential disclosures include:
- Conference talks and posters.
- Published abstracts.
- Theses and dissertations placed in a library or online.
- Preprints.
- Public grant abstracts.
- Demo days and pitch competitions.
- Pitch decks sent without confidentiality terms.
- Offers to sell or public use.
Before any of these, consult your technology transfer office or patent counsel. The guide to technology transfer and invention ownership explains the institutional role. Whether a talk, poster or meeting counts as a disclosure depends on the facts, so ask about the specific case rather than relying on a general rule.
What a patent costs
Budget for government charges, professional work, and later expenses. A low initial filing fee does not represent the full cost of securing and maintaining protection.
| Cost layer | What to budget for |
|---|---|
| USPTO fees | Filing, search, examination, applicable surcharges, and issuance |
| Professional fees | Drafting and prosecution: handling the application through examination; costs vary widely with complexity |
| Later expenses | Responses to office actions, maintenance fees, and foreign filings |
In the USPTO fee schedule effective January 19, 2025 (last revised November 1, 2026), each figure below reads undiscounted / small entity / micro entity. The utility basic filing fee is $350 / $140 / $70, but a small entity that files electronically pays $70, and paper filings carry an extra non-electronic filing fee. The search fee is $770 / $308 / $154 and the examination fee is $880 / $352 / $176, so the core government fees for an electronic filing come to $2,000, $730 or $400. More than three independent claims or more than 20 claims in total add surcharges, and the utility issue fee of $1,290 / $516 / $258 is due only if the patent is allowed.
Small-entity status generally covers businesses with 500 or fewer employees, including affiliates, independent inventors, and nonprofits such as universities, subject to conditions. Micro-entity status adds income and filing-count limits, or a university-employment basis. Misclaiming status has consequences; confirm eligibility under USPTO rules with a registered practitioner.
Ask for an estimate identifying assumptions and exclusions, including responses to office actions—USPTO communications requiring an applicant’s response. Fees change; check the current USPTO fee schedule.
Freedom to operate is a different question
A patent gives its owner a right to exclude others, not permission to make or sell a product. Freedom to operate means assessing whether commercial activities could infringe others’ patent rights. Counsel reviews relevant patents against the proposed product and market.
Deep-tech investors often ask about both patent protection and freedom to operate. Present the assessment’s scope and unresolved issues accurately; the guide to presenting a technology startup to investors explains how to communicate your intellectual property position.
When to hire a registered practitioner
Only USPTO-registered patent attorneys and agents may represent others before the USPTO in patent matters. Drafting claims requires specialized judgment about technical scope and disclosure support. Bring experimental records, drawings, publication plans, and ownership documents.
Get help before public disclosure, investor meetings, or license negotiations. For institutional inventions, coordinate with the technology transfer office before commissioning work. The guide to licensing university technology explains how patent costs and control of prosecution fit into a license negotiation.
Low-cost help from the USPTO
- The Patent Pro Bono Program matches under-resourced inventors and small businesses with volunteer practitioners through independently run regional programs nationwide; eligibility is mainly income-based and locally determined.
- The Law School Clinic Certification Program lets supervised law students handle patent and trademark matters for eligible clients, with client criteria set by each participating school.
- The Pro Se Assistance Program provides general information, not legal advice, for applicants filing without a registered practitioner.
- Patent and Trademark Resource Centers are USPTO-designated public, state, and academic libraries that assist with patent and trademark searching.
Verify current availability and eligibility with the USPTO or participating provider. Be cautious with paid invention-promotion firms promising licensing results.
This guide provides general information, not legal advice. Work with a registered patent practitioner on filing strategy, disclosure risks, and claims.
Frequently Asked Questions
Does a provisional application give me a patent?
No patent is granted from a provisional alone. It can establish a date for adequately described material used in a subsequent non-provisional application.
Can I patent an invention after presenting it?
Possibly, depending on what was disclosed and when. The US inventor-disclosure grace period may help, while foreign rights may already be affected. Have a registered practitioner review the presentation promptly.
Does the provisional year shorten my patent term?
The provisional year does not count toward the general utility patent term. That term generally runs from the earliest non-provisional filing on which the patent relies.
Can I file a patent application myself?
Applicants can file without a registered practitioner. Preparing an adequate description and effective claims requires specialized skill, so professional help is advisable. USPTO self-filing assistance supplies general information rather than legal advice.
