I have received a written opinion from the Korean International Searching Authority (ISA). The opinion states that the application contains two inventions which have a common technical feature that lacks novelty and inventive step with respect to cited prior art, and thus concludes that the claims do not have a single general inventive concept.

However, the written opinion goes on to state that both sets of
claims (for the two inventions) are novel over cited prior art,
involve an inventive step, and have industrial applicability.

I take all this to mean that (1) the ISA believes the claims are
allowable (subject to local constraints such as allowable subject
matter), and that (2) a restriction requirement will probably be
received after entering US national stage. Is this a reasonable
interpretation?

Thanks.
