The Timing Question: When to File
- Too Early: File before product-market fit, spend ₹5L on a patent for a feature nobody wants. Waste.
- Too Late: Wait until Series B, but competitors already copy your idea. Too late — prior art defeats your patent.
- Just Right: File when you have PMF and the idea is defensible (non-obvious, novel). Seed stage, right after you find traction.
Pro tip: Provisional patents (₹1–2L) buy you 12 months to assess patentability before committing to full patent (₹4–5L). Smart founders file provisional, see if competitors copy, then decide on full patent.
Global Filing Strategy
- Phase 1 (Seed): File provisional in India (cheap, fast). File trademark everywhere (US, EU, India — ₹10–30K total).
- Phase 2 (Series A): Convert Indian provisional to full patent. File PCT (Patent Cooperation Treaty) for global coverage. Cost: ₹20–30L but covers 150+ countries.
- Phase 3 (Series B): File full patents in US, EU, China if your product is globally valuable.
