<p>The WIPO Digital Access Service (“DAS”), available at <a href="https://www.wipo.int/das/en/">https://www.wipo.int/das/en/</a>, allows you to meet requirements for providing priority and similar documents in respect of participating Offices, without the need to obtain and send multiple certified paper copies of an application.</p>
<p>Instead, you ask the Office where you are claiming priority (“Office of Second Filing” or OSF) to download a copy of the document directly from a digital library, normally held by or on behalf of the Office where the earlier application was filed from which priority is claimed (“Office of First Filing” or OFF).</p>
