Paul Walsh


Paul is an industry-acknowledged leader in all aspects of brands law. He specialises in the entirety of the work – from brand and design creation to brand enforcement and exploitation. In terms of exploitation and use of brands, he advises not only on IP rights but day-to-day use of brands in market. This includes advertising, specific product regulatory regimes and relevant consumer law.

As well as being a well-renowned litigator, Paul’s litigious practice is one of dispute resolution, in which the commercial avoidance and settlement of disputes is every bit as important as victories in the courts. Paul is a member of the International Trademark Association.

Paul has lectured and taught widely on brands and dispute resolution. In addition to his many corporate clients, he also acts as the legal adviser to the British Brands Group – a UK industry body of brand manufacturers which is widely acknowledged as the UK industry “voice for brands”.

Paul’s cases have defined the law of brands: creating the law of intermediary liability (L’Oreal v eBay), registrability of non-traditional trade marks (KitKat), genuine use of UK and EU trade marks (Walton v Verweij) and “targeting” of UK/EU trade (BDO v BDO Unibank).
