Spell Penetration Feat - used only on creatures?

[Korwynne]

Spell Penetration says: "Gain a +2 bonus on caster level checks (1d20 + caster level) made to overcome a creature's spell resistance."

If someone were to have a cursed item where the save when casting "remove curse" is 10 + caster level of that item, would spell penetration help?

If not, is there any feat that would assist in the situation where a person is looking to reduce the roll necessary to remove cursed items?

The caster level check required with Remove Cure is not spell resistance. Spell Penetration would not help with that.

Thanks! Any idea on what feats might?

Mage's tattoo. There's also an orange prism ioun stone (not a feat but still an option). Caster level bonuses seem few and far between.

Thanks!
