In India, patent agents are registered with the Patent Office and are authorised to draft, file, and prosecute applications. Patent attorneys (advocates) may additionally represent clients in IP litigation before courts.
Prosecution vs litigation
Agents handle patent searches, draft provisional and complete specifications, examination responses, and hearings before the Controller of Patents. Attorneys lead infringement suits, oppositions requiring court strategy, and portfolio due diligence for M&A.
Choosing your advisor
Many portfolios use both: agents for patent drafting and prosecution and attorneys for enforcement. Verify registration status and sector experience in pharma, software, or mechanical arts.
