Intellectual property law covers registering and protecting trademarks (brand names, logos), copyright (creative and written work, software, music), patents (inventions), and industrial designs, as well as pursuing or defending against infringement. The relevant statutes are the Trade Marks Act, 1999; the Copyright Act, 1957; the Patents Act, 1970; and the Designs Act, 2000. India also recognises "passing off" as a common-law remedy for unregistered trademarks that have built up reputation and goodwill.
Trademark registration is generally advisable before or immediately upon launching a brand — an unregistered mark can still be defended under passing-off principles, but registration gives significantly stronger and faster legal protection. Copyright in original creative work exists automatically upon creation without needing registration, though registration provides useful evidence of ownership and date of creation if a dispute arises. Patent protection, unlike copyright, requires a formal application and examination process, and the invention must be novel and not already disclosed publicly before filing.
Delhi High Court in particular has a dedicated Intellectual Property Division handling a large share of India's trademark, copyright, and patent litigation. Whether you're launching a brand and want to search and register a trademark, responding to an infringement notice, or pursuing someone who's copied your work, it's worth getting legal input before taking any public action, since IP disputes often turn on documentation of who used or created something first.
