Design registration is for the visual features of an article — shape, configuration, pattern, ornament. It is fast and inexpensive in India, but it must be filed before the design is published or sold; novelty is a condition.
Trademark protection for a shape or packaging (trade dress) is possible but demands proof that the look identifies you in buyers' minds — a much higher bar, usually built over years of use.
A practical sequence
- File the design before launch (novelty preserved, cheap, 15-year ceiling).
- Build recognition; if the look becomes your identity, layer trademark/trade-dress claims on top.
- Meanwhile the brand name and logo should be trademarked on day one.
