In this scenario, the footballer can utilize trademarks to show that the clothes are made by his company. A trademark will allow him to protect his brand name, logo, and any unique identifiers associated with his clothing range, helping to distinguish his products in the market and preventing others from using similar marks that could cause confusion.
While registered designs may protect the aesthetic features of his clothing, and copyright could apply to original artwork or designs, trademarks are specifically intended to signify the source of goods or services. Geographical indications are typically used for products having a specific geographical origin and qualities or reputation due to that origin, and patents are for inventions and not applicable to clothing designs. Therefore, trademarks are the most relevant form of intellectual property in this context.
