"I would rate K & S Partners among the best IP firms I've worked with in India," says a client. The firm continues to be in the top Tiers of the patent rankings, where it is highly rated by peers and clients. A competitor notes: "I have a lot of respect for them." Though the firm lost litigation partner Rajeshwari Hariharan in the last year, a peer notes that: "They have strength in depth when it comes to litigation." A few of the partners recognised for their litigation abilities include Jyoti Sagar, Calab Gabriel, Rajendra Kumar and Kenneth Benjamin.
The firm represented client Qualpro Diagnostics, as appellant, before the Delhi High Court in cases regarding the filing of serial oppositions. Completed in mid-2010, these cases considered issues of abuse of methodology and process of the Court and addressed detailed guidelines for the procedure that should be adopted by the patent office.
