How these questions are made

Each question was drafted with AI from the exam’s own source materials (the MPEP and the USPTO’s rules), then answered blind by a second AI model from a different company; a question was kept only when that check reached the same answer, found one defensible choice and no defect. Dates are checked against the federal holiday calendar by code. Questions use the MPEP revision the exam tests; check the current rule before relying on one in practice. These are practice questions, not legal advice.
