AI prior art search tools: a 2026 buyer's guide for defendants
AI doesn't replace a patent attorney's judgment. It does replace the search step that used to cost $20,000 and take three weeks.
Patent term and expiration
Patents don't last forever. They don't even reliably last 20 years. The expiration date that actually matters depends on the earliest filing date, the maintenance schedule, and any USPTO or FDA delays the patent owner can claim back.
