Charan advises clients in patent and other intellectual property litigation, primarily involving pharmaceutical, software, communications network, medical device, mechanical and biotechnology inventions. He represents clients through all stages of litigation, including trial, inter partes review and other PTAB proceedings, and appeals. Charan also leverages his trial experience to advise clients on IP portfolio development, provide pre-litigation and freedom-to-operate opinions, prosecute high-value patents relating to a variety of technologies, and review key assets in transactional due diligence.

He represents clients in various types of litigation, adapting the core strategy to fit clients’ business needs and objectives. His outside-the-box approach is highly valued in branded-side Hatch- Waxman Abbreviated New Drug Application (ANDA) patent litigation and bet-the-company patent litigation between multinational competitors. His ability to winnow cases to key strategic issues and evidence gives technology clients an advantage in efficiently defending against non-practicing entity litigation. Charan’s broad technical background makes him well-suited both to delve into obscure points with experts while still simplifying complex issues for a lay audience. For this reason, Charan has been retained by clients to handle IP disputes relating to diverse technologies ranging from software, Internet routing and content delivery technologies, PET scanner crystallography, infrared missile seekers, genetically modified crops, automation equipment, mobile telephone handsets and computer hardware, and communications protocols.
