The Protector title and Fenn Rau's ability DO NOT use the same phrasing as each other. Yes they both say "when defending" and "in arc at range 1" but the part between those two is what matters most to this discussion:
Fenn Rau triggers from "if the enemy ship". This is the same as Jax, Fett(scum), and most other abilities that reference range during an attack. Inq will not trigger this ability because it's just the range of an enemy ship rather than the range of the attacker.
This is different from the Protector title that says "if the attacker". The only other card I can recall that uses "the attacker" and a reference to range is autothrusters. This is why the Protector title should work against Inq at range 2-3; both use the same trigger albeit at adifferen range conditions.
