European patent and Unitary Patent budgets

Build a common procedural baseline

European proceedings include filing, search, examination and grant fees. The application budget also includes professional work through that procedure. Organise these stages before comparing the protection selected after grant; the EPO's overview of the application process provides the procedural framework.

Use the same claims, pages and complexity in both variants. Record the first filing and any PCT route consistently, then review the expected office actions and time to grant. This common baseline helps you see whether a budget difference comes from the post-grant strategy or from an unrelated change to the application assumptions.

Define the geographical coverage precisely

A Unitary Patent covers the participating states for which the system is effective when its unitary effect is registered. That patent's territory remains fixed for its lifetime. Use the EPO's register and territorial guidance to identify the coverage relevant to your scenario, together with any additional countries your project needs.

Write a coverage list for each alternative before comparing totals. Group markets by their importance to the business, and identify manufacturing and licensing priorities. A clearly described geographical result is more useful to the project team than two totals whose territory lists differ without explanation.

• Priority sales markets
• Manufacturing and supply-chain locations
• Licensing territories
• Additional countries outside the selected unitary coverage

Describe the conventional European option country by country

With a conventional European patent, the selected national validations and subsequent national renewal arrangements form part of the post-grant budget. Give each retained country its own place in the comparison so the cost of the chosen territorial set can be reviewed clearly.

For budgeting, note the local professional work and formalities assumed at grant, then follow the maintenance years. Review which work is included in the firm profile and which client-specific inputs you have adjusted. This creates a useful record for discussing a narrower or broader set of countries with the attorney handling the application.

Identify the unitary renewal component

The proprietor pays one Unitary Patent renewal fee to the EPO for the patent's unitary coverage. Keep that component distinct from any additional national protection selected for the project. The EPO publishes the renewal framework and its cost information for the Unitary Patent.

Compare the unitary option over the same horizon as the conventional option. Include the professional administration work you expect for each, and review the assumptions used for supplementary countries. The annual breakdown then shows both the recurring commitment and the effect of your chosen territorial strategy.

Prepare two controlled scenarios in Patfee

Begin with the applicant information, first filing and technical characteristics. Select the European procedure and intended territories. Prepare a conventional post-grant variant, then a variant including the Unitary Patent. Keep the assumptions that are common to both scenarios unchanged so each comparison has an identifiable purpose.

Use clear report titles, such as a conventional reference and a unitary alternative, with the same project identifier. After changing the strategy, check the assumptions summary before calculating again. Review the selected procedures, territory list, professional-fee profile and maintenance duration in the new result before placing the reports side by side.

Compare official fees and professional work separately

Office fees and attorney fees answer different budgeting questions. The first identifies procedural charges under the selected framework; the second records the professional work assumed for the dossier. Use the separate lines to discuss the expected representation with a firm and to identify the inputs that should be tailored to the client.

Where a reduction is selected, review its conditions using the question-mark help and record the facts supporting the assumption. Use consistent currency conversion assumptions for both variants. Examine the marked items of a partial result directly, then update and recalculate the scenario before presenting the resulting budget for approval.

Present the choice as a budget and coverage decision

Start the review with the territorial coverage, then show the annual spending and total for the chosen horizon. Explain which costs occur before grant and which follow the post-grant decision. This sequence lets commercial, technical and finance colleagues discuss the same protection objective with a common set of assumptions.

The PDF provides the assumptions, expense explanations and legal references attached to the calculation. Keep the comparison with the project record and identify when to review it again. A later change in markets, application complexity or professional work can then be assessed against a documented reference rather than an isolated historic total.
