Attack Roll Modifiers and See Invisibility

[Cloudyshine]

So this is just a tiny issue that I just can't seem to find the answer to. It lists in the rules that an Invisible creature gets a +2 on attacks, on top of their opponent being denied their Dexterity Bonus to AC. But it never specifies if this refers to being invisible regardless of if your opponent has See Invisibility or not, or if it refers to being invisible to your enemy. So the question is:

If you're invisible and attack someone who has some form of See Invisibility, do you get the +2 to attack?

Logic dictates you don't, but maybe I've overlooked something.

No as you aren't invisible to them. Invisibility is a condition, if you are invisible to the target the effects apply, if not they do not. If it was a flat +2 whether or not your enemy could see you they wouldn't have included "An invisible creature gains a +2 bonus on attack rolls against sighted opponents".
