  13. INVENTION OF USE • Considered as having inventive step if it can generate unexpected effect • Example: • Prior art: A lubricant having cooling effect. • Claimed invention: A grinding slurry containing said lubricant. • Invention step: NO

  14. INVENTION OF SUBSTITUTION • Considered as having inventive step if it generates unexpected effect. • Example: • Prior art: Water pump comprising an electrical motor. • Claimed invention: Water pump comprising a hydraulic motor. • Inventive step: NO
