Maintenance fees due at 3.5, 7.5, and 11.5 years (utility patents)
A utility patent costs $10,000–$30,000+ in total, including USPTO fees ($320–$1,760 filing) and attorney fees ($5,000–$20,000+). Design patents are cheaper: $2,000–$5,000 total.
A provisional patent (PPA) costs $160–$320 in USPTO fees plus attorney fees ($1,500–$3,000). It establishes a priority date and gives you 12 months to file a full utility patent. It never becomes a patent on its own.
Utility patents last 20 years from the filing date. Design patents last 15 years. Maintenance fees are due at 3.5, 7.5, and 11.5 years for utility patents.
Yes, but it's risky. Pro se (self-filed) patents often have weaker claims. For valuable inventions, an experienced patent attorney helps maximize protection.
