2.4.3 Multiple priorities claimed for different inventions in the application with an intermediate publication of one of the inventions 

EP claims priority of P1 and P2, D is the disclosure of A+B.

Claim 1 has a valid priority of P1 for its subject-matter, thus publication D is not state of the art under Art. 54(2) against this claim. Claim 2 cannot benefit from the priority of P1, as it does not concern the same subject-matter. Thus publication D is state of the art under Art. 54(2) for this claim (see G 3/93). It is immaterial whether claim 2 is in the form of a dependent or an independent claim.
