Piramal Healthcare Ltd obtained a common ex-parte ad-interim order from the Mumbai High Court on April 9, 2009 restraining four companies from using trademarks similar to its product Esgipyrin. Piramal Healthcare is a registered proprietor of the mark 'Esgipyrin' and the company has been using the trademark since 1974.

The four companies that have been restrained via this order are Endolabs Healthcare Pvt Ltd for their trademark Easipyrin, Endolabs Lifescience for their trademark Elgipyrin, Spachem Laboratories Pvt Ltd for their trademark Zypyrine and Endolabs Ltd for their trademark Agepyrine.

The order states that the companies have introduced the infringing products for the same ailment as countered by Piramal's Esgipyrin and that it has been prima facie seen that the product is deceptively similar to that of the original product. The order further goes on to state that the companies have been engaged in a deliberate, dishonest and fraudulent act of counterfeiting and are passing off their products as that from Piramal Healthcare, a statement issued by Piramal Healthcarre said.
