Protecting ideas, defending brands and shaping the future of intellectual property since 1990.
Biswajit Sarkar is a leading intellectual property law firm, guiding inventors and businesses from Kolkata to the world since 1990.
We help clients protect ideas, defend brands, and turn creative and technical work into secured, enforceable rights. Our patent, trademark, copyright and corporate law teams pair sharp legal thinking with practical, business-first advice — so every client walks away with protection that actually works.
Founded in Kolkata in 1990, Biswajit Sarkar began as an intellectual property law firm and, through years of working across the many layers of IP law, grew into a practice that also covers corporate affairs, international trade and information technology.
Our international litigation experience includes empanelment with the U.S. Consulate in Kolkata, the British Deputy High Commission in Kolkata and the French Trade Commission in Mumbai, alongside ties to national and international chambers of commerce.
