The exam at a glance
Tested edition: MPEP 9th ed., Revision 01.2024 (November 2024). Our bank follows the same edition. Changes since then sit in their own topic and stay out of the mocks. What the exam tests
The exam is mostly fact patterns: filings, dates and deadlines. So is our bank.
An engineer demonstrated her drone-landing system at a public trade show on March 2, 2025. Her nonprovisional application, which claims no earlier benefit or priority, was filed on March 9, 2026, and is subject to the first-inventor-to-file provisions. The examiner rejects the claims as anticipated by the demonstration. What is the effect of the demonstration?

Older exams the USPTO made public, each explained against today’s MPEP, with changed answers flagged.
One per topic: the rule, the exam trap and a takeaway you can remember.
