It refers to the use of deceptive or abusive practices intended to harm competitors. The private detective then acts on surveillance of the offending company, evidence gathering, and legal support, in order to provide you with all the necessary elements to respond effectively.
Although already closely regulated by public authorities, this illegal practice causes significant financial losses for the company whose products (clothing, accessories, medicines) are copied. The private detective can investigate, infiltrate, gather and examine evidence, then work hand in hand with the competent authorities.
