Counterfeit goods and piracy costs the Irish economy €909 million in lost sales, an EU report published in June found.
The European Union Intellectual Property Office (EUIPO) 2019 Status Report estimates that this is equivalent of €192 per citizen per annum, and 5.4% of total sales.
Sales losses from counterfeiting and piracy loss are estimated at €60 billion a year across the EU.
Online shopping has led to a surge in the availability of counterfeit goods.
China is the main source country for goods infringing intellectual property rights (IPR).
Cigarettes and toys are the top two categories for counterfeit items seized across the EU.

This represents an increase since a similar report was published by the two organisations in 2016.
Prosecutions in Ireland for suspected counterfeit goods are under Section 92 of the Trademarks Act 1996.
