What evidence is needed to demonstrate IP infringement?

Some of the necessary evidence includes: proof of ownership of the IP right, such as registration certificates and affidavits of ownership of copyright; photos or specimens of the infringing goods or of other infringing materials such as brochures, invoices, and receipts; and proof of damages incurred such as financial and sales data of the infringing goods and testimony on loss of profit. In an administrative action filed with the IPO- BLA, evidence consisting of documents from a foreign country must be notarised, and thereafter legalised by an Apostille (or legalised by a Philippine foreign officer stationed in the foreign country, if the foreign country is not a party to the Apostille Convention).
