Patent

Trade mark

Case studies show that the firm has assisted clients with prosecution matters across a diverse range of industry sectors. 

In a judgment dated July 12 2018, the Delhi High Court has allowed a plea of patent infringement by Koninklijke Philips Electronics (Phillips)
In the case of Christian Louboutin SAS v Abubaker & Ors, a single judge of the Hon’ble Delhi High Court summarily dismissed a trade mark infringement and passing off suit on May 18 2018, without issuing summons to the defendants, holding that use of a single colour rather than a combination of colours does not qualify as a mark under Section 2(1)(m) and as a trade mark under Section 2(1)(zb) of the Trademarks Act 1999 (hereinafter the Act).
