Innovation Capital Law Group offers flat rate cost estimates for initial filings of PCT national stage entry in the most common PCT member countries.
PCT national phase filing costs vary widely. Factors such as translation and excess claim fees can add thousands to the initial filing cost of a particular PCT country. The European Patent Office (EPO), a regional patent office that accepts a single application to cover multiple European Union countries, charges an excess claim fee of over US$300 for each claim above 15. For example, a PCT application with 25 claims, which would not be unusually high for a U.S. utility patent application, would incur over $3,000 in excess claim fees when entering the national stage at the EPO.
PCT applicants approaching the national stage deadline can save a great deal of money by planning ahead with their patent attorneys to understand the particular costs associated with filing in each desired foreign IP office. Instructing foreign associates early on to proceed with the national phase filings can also save money by avoiding late charges for required filings such as signed formal documents and translations.
