Hindustan Unilever lost a trademark case for its 127-year-old Sunlight soap brand to a little known Kerala-based company called the Thai Group. While Sunlight was once HUL's most popular soap, its sales had declined nationally as brands like Surf and Wheel became more popular. The Thai Group, founded in 1984, had launched its own soap brand called Sunplus that earned around 10 crore annually. HUL had sued the Thai Group for infringing on the Sunlight trademark, but lost the case as the court found HUL had not used the Sunlight brand for detergent in over 60 years.
