Dan Smith, from Newbury, created healthy drinks company Thirsty Beasts in 2018, and the US firm filed a legal challenge against him.It claimed customers would confuse both Mr Smith’s slogan – “Rehab the beast” – with its “Unleash the beast” line. The case, which was dismissed, cost Mr Smith more than £30,000 in legal fees. He said he and his wife had ploughed every penny they had into launching the business. After registering his first trademark in the UK in 2016, Mr Smith then filed the Thirsty Beasts logo. Billion-dollar company Monster Energy objected to his application, claiming Mr Smith’s slogan was too similar to its own.The UK Trademark Office ruled in favour of Thirsty Beasts, but Monster Energy appealed the decision.
