Protection of the seller's intellectual property rights on Allegro - an effective response without a court hearing
by Marcin Tomczak on Jan 25, 2026
Introduction
In disputes over intellectual property rights infringement on the marketplace, an appropriate strategy and professional out-of-court actions can effectively protect the interests of entrepreneurs without the need for lengthy court proceedings.
Online marketplaces like Allegro are not only a place for price competition but also a frequent source of intellectual property infringement. Unlawful use of EAN codes, trademarks, or product images is common and generates real losses for brand owners.
Case description
A client selling on Allegro has repeatedly encountered competitors copying their EAN codes, trademarks, and product images. This behavior has led to customer confusion, reduced brand recognition, and decreased sales. Previous attempts by the client to contact the infringers themselves have been unsuccessful.
Solution method
After analyzing the situation, we implemented an action plan that included thorough documentation of violations and the preparation of formal cease-and-desist letters, citing the appropriate legal grounds. Acting on behalf of the law firm, we sent formal letters to the violators, outlining the consequences of further violations and the possibility of legal action.
Effects
Professionally prepared notices brought immediate results – the infringing entities withdrew their offers or modified them, eliminating infringements of EAN codes, trademarks, and images. The client secured his interests without having to engage in costly and lengthy litigation.
Summary
This case study confirms that effective intellectual property protection on online marketplaces begins with a carefully crafted out-of-court strategy. For many infringers, the mere engagement of a professional law firm and the presentation of real legal risks are sufficient motivation to cease unfair practices.
