Frying pan Teflon damage
These don't look like scratches to me, more like heat damage. You are either using it for the wrong tasks (e.g. steak), or using it improperly (e.g. preheating it), or the extremely frequent use is simply too much and tires the material. 

Without knowing more about your cooking habits, we can't tell you what to change. 

Edit: just realised you are using it 3 times a week, not 3 times a day. Scratch the last reason (too frequent use).
