I have to file a “declaration of claims correspondence” to participate in the PPH programme. How do I file this declaration?

The EPO requires the applicant to submit a “declaration of claims correspondence” stating that the claims sufficiently correspond. This is done by ticking the relevant box in section D. of EPO Form 1009. No separate document needs to be filed.
