FAQ: Patent Cost Questions Answered

Q: Can I patent an idea without a prototype?
A: Yes! USPTO requires "enablement" (clear descriptions/diagrams), not physical prototypes. Example: Software patents often use flowcharts.

Q: What's the cheapest way to patent internationally?
A: File a PCT application within 12 months of your US filing, then selectively enter countries. Costs 40% less than direct national filings.
