Poland is not different from the rest of the world and counterfeit seems to be a serious issue here. Although Allegro tries to tackle the problem, users impressions on that are mixed to say the least. My feeling is people much too often try to resolve the situation on their own. Fortune favours the bold, right? And legal assistance could by decisive to help with stopping fake products being offered on Allegro, still the largest online e-commerce platform in Poland. Why? For starters - more or less formal complaint is necessary to open the process of stopping suspicious auctions. And to navigate through the waves later so to speak. It can all end up at the court or even lead to an opening of criminal proceedings against fake products seller. It is not easy without legal knowledge, belive me.

Further steps depend on what Allegro’s response would be. Auditing your intellectual property rights will be probably necessary before since legal measures generally apply only to what is protected in Poland. So to counteract trademark infringement you need to have your trademark registered, to stop copying ideas your products are based on you need to have a patent granted (eg. european patent) or utility model protected and so on. And to make that protection fully working data such as trademark registration number, graphical representation of registered Community design, patent number etc. is absolutely essential.
