01
Prometric-Replica Interface

The same layout, navigation constraints, and lag-simulated PDF viewer as the actual Prometric testing environment. No Ctrl+F. No shortcuts. Practice under real conditions.

02
100 Official USPTO Questions

2003 October Morning and Afternoon sessions — drawn directly from official USPTO past exams. Every question is real. Every answer key is verified against the official USPTO model answers.

03
Integrated MPEP Viewer

One click from any question opens the relevant MPEP section — exactly as it appears on the actual exam. Session history, replay, Exam and Practice modes included.

Patent law is not a rulebook — it's a record of disputes. Every section of the MPEP exists because someone tested a boundary. The USPTO exam knows this. Its questions are drawn from real edge cases, real thorny situations, real adjudicated outcomes.
