Frequently Asked Questions
How long does the patent process take?
Provisional patent: filed immediately (valid 12 months). Design patent: 12-24 months to issue. Utility patent: 18-36 months average (can take 5+ years). Expedited examination ($2,000-$4,000 extra) can reduce to 6-12 months.
Is a patent worth the cost?
It depends on the commercial potential. A patent is worth it if: your invention has significant market value, competitors could copy it, or you plan to license it. Many patents are never commercialized. Consider the total cost ($5,000-$20,000+) vs potential revenue.
