From the Objective-C language manual syntax definitions:

        protocol-declaration:
        @protocol protocol-name
        [ protocol-reference-list ]
        [ interface-declaration-list ]
        @end

        protocol-declaration-list:
        @protocol < protocol-list  > ;

        class-declaration-list:
        @class class-list ;

Which is hopefully self-explanatory.  So I guess you need:
@protocol < SomeProtocol SomeOtherProtocol >;
