Firm Profile

Lall & Sethi was founded in 1994 by Chander M Lall and Sandeep Sethi, both of whom are designated senior advocates. An IP boutique with a focus on IP law, including trademarks, copyright, designs, patents, confidential information and trade secrets, L&S provides a complete range of services ranging from filing and prosecution of applications, oppositions and cancellation proceedings, searching and watching services, renewals, licensing and registered users to franchising, IP audits and enforcement of rights through civil, criminal or administrative measures.

Lall & Sethi ensures that its attorneys and staff stay abreast of the best practices from across the globe, and understand and respect client needs. Training is also imparted on local practices of courts and IP offices in the region. This training and knowledge have resulted in some of the ground-breaking decisions in the region, with IP legislation starting life on the desks of Lall & Sethi offices – be it decisions on well-known and famous marks, version recordings in music, or unique region-specific John Doe and Anton Pillar-type search and seizure orders. All litigation, including drafting and court appearances, are handled by in-house experienced litigators.

The firm prides itself on having one of the best IT systems in the world. The firm’s IP management software, developed in-house, ensures that timely responses are sent and deadlines are strictly adhered to. The docketing systems have minimal manual interface, virtually eliminating human errors. An assembly-line approach ensures that each task is undertaken by a member of staff who is thoroughly familiar with it, having undertaken it multiple times after receiving thorough training. On client reporting, it is possible for a client to monitor the work on a real-time basis by requesting password-protected access to the database where all files are completely digital. An optional fixed-fee schedule ensures that the cost benefits of repetitive services on bulk files and use of efficient systems are passed on to the client. The client has full knowledge of, and access to, the administrative staff, often communicating with them on a first-name basis.
