TOP TIPS
For European Patents
- 15 Claims - Significant extra fees are charged by the European Patent Office (EPO) for each claim over 15. Therefore, if possible, slim your claims down.
- Novel claims - Consider amending the claims prior to filing the European patent application to make them as novel and inventive as possible. This will help reduce prosecution costs.
- 31 months - If filing a European patent application from an international PCT patent application, you have until 31 months from priority to do so, which is longer than the usual 30 months of many countries.
- Claim references - Amend the text of the claims to include the reference number of each element. This will help to reduce prosecution costs.
- Claim types - A European patent can only have one independent apparatus claim, one independent method claim, and one independent product-by-process claim. If there are more than one of these types of claims, make them the subject of a divisional application.
