Depends on what type of pen the assailant is using. My limited googling gave 461 psi as the pressure needed to puncture skin, and 1 mm^2 as a good approximation of the area of a ball-point-pen.
1 sq in is roughly 645 mm^2 so you need 461 lb / 645 mm^2 multiply by the area used, 1 mm^2, and you get the answer of approximately
0.7 lbs of force
