Our foreign patent filing workflow

Step-by-step workflow for Sun IP’s foreign patent filing services.

Sun IP’s EP Validation service

When a European Patent (EP) is granted, it must be validated in every country where protection is required. The process for EP validation involves completing country-specific actions within three months of the European Patent Office (EPO) grant date. Each jurisdiction comes with its own set of requirements, translation guidelines, and filing frameworks.

At Sun IP, we make the process effortless. From agent coordination to document management and cost clarity, we offer a smarter, more transparent way to manage EP validations, all from a single, secure platform.
