Do attack bonuses from different feats stack?

Question

Like the +1 bonus from Implement Expertise and the +1 from Versatile Expertise?

Answer 1

NO, they do no stack

Typed bonuses do not stack with same typed bonuses. In your example the feats do not stack.

However, some feats provide untyped bonuses.

For instance the Fighter Feat Fighter Weapon Specialization provides an untyped +1 to damage. This will stack with the feat bonus to damage from a focus feat (Heavy Blade Focus, Light Blade Focus etc).

Answer 2

Bonuses of the same type do not stack. In this case, both are listed as Feat bonuses, so they do not stack.
