EUIPO writes in the executive summary:
“Internet websites and mobile applications that provide access to content, goods or services that infringe intellectual property rights (IPR) on a commercial scale use the sale of advertising space as one of their revenue sources. In addition to providing a revenue stream to IPR infringers, the presence of advertising for legitimate brands on websites and mobile applications that infringe IPR can confuse consumers. It can lead them to mistakenly believe that the site or application they are accessing provides access to legal content, goods or services.”.
