Pct Filing Cost Depends on Filing Fees and Country Selection

Three main charges make up the international-stage filing expenses:

• International filing fee: The USPTO's August 2026 schedule lists $1,667 for the first 30 sheets, reduced to $1,542 for qualifying electronic filings without an ePCT ZIP file or $1,416 with one.
• International search fee: The charge depends on the competent International Searching Authority. Under the same schedule, a search performed by the USPTO costs $2,400 for a regular entity.
• Transmittal fee: The USPTO charges $285 for regular entities, $114 for eligible small entities, and $57 for eligible micro entities.

For example, a regular-entity applicant filing electronically with a qualifying ePCT ZIP file and selecting the USPTO as the searching authority would pay $4,101 in these three fees, assuming no additional charges.

This amount excludes application preparation, excess-sheet fees, and later national phase expenses.

Discounts do not apply uniformly across PCT charges.

USPTO small-entity and micro-entity status can reduce eligible transmittal and USPTO search fees. WIPO international filing fee reductions follow separate requirements, including qualifying electronic filing methods and certain applicant eligibility criteria.

The applicant's residence, nationality, and chosen receiving Office can also affect available filing arrangements.

These distinctions matter when evaluating PCT application procedures, particularly where more than one competent receiving Office or searching authority is available.

The following comparison identifies the main expenses rather than presenting a single price that may not fit every application.

Actual fees depend on the filing date, entity eligibility, application details, and local rules.

A U.S. .ational-stage application may require several official fees rather than one filing charge. Likewise, the EPO fee structure differs from those of individual national patent Offices.

Translation costs can make two otherwise similar filing plans look very different.

A lengthy English-language application entering Japan or China may require substantial technical translation work. The final expense depends on the number of words, specialized terminology, and applicable translation requirements.

European filings need separate consideration. The EPO has its own language rules, while validation after grant may create additional requirements in selected states.

Local attorney fees cover work such as preparing entry documents, checking formalities, and communicating with national patent Offices. Companies pursuing protection in several jurisdictions can address these charges through coordinated patent prosecution planning.

For PCT applications filed through the USPTO, each sheet exceeding 30 adds $19 under the August 2026 fee schedule.

National Offices apply different rules. Some charge extra for claims beyond a specified number or for particular claim structures.

A lengthy specification can also increase translation costs without increasing every jurisdiction's official filing fee in the same way.

National phase entry is not the end of the payment process.

Patent examiners may reject or object to claims, requiring amendments or written responses. Additional prosecution work can increase attorney expenses, while certain procedures carry separate official fees.

Foreign exchange changes may affect the amount applicants pay in other currencies.

Granted patents can generate further maintenance or renewal fees. These expenses should appear in a long-term patent portfolio budget, rather than being included in the quoted initial filing cost.

Consider a company planning protection in the United States, Europe, and Japan.

It would first pay the applicable international-stage fees. At national or regional phase entry, the company would then incur separate charges for its three selected patent markets, including any required translations and local representation.

Adding China and South Korea would introduce two more sets of national expenses.

The international filing fee does not multiply by the number of countries selected, but national phase expenses accumulate with each additional market.

For preliminary planning, applicants can use:

Estimated budget = International-stage costs + National-phase entry costs + Expected prosecution costs

Each component should reflect current official fees and a realistic estimate of professional expenses.

Most national and regional phase deadlines fall 30 or 31 months after the earliest priority date, although some jurisdictions have different rules.

For example, the United States generally uses a 30-month deadline, while the European Patent Office and South Korea generally allow 31 months.

These deadlines determine when applicants need funds available for national phase entry. Before committing, they should confirm the applicable payment dates, translation requirements, and national Office procedures.
