I. The posing of a new problem does not represent a contribution to the inventive merits of the solution if it could have been posed by the average person skilled in the art. Such is the case where a problem consists solely of eliminating deficiencies in an object which come to light when it is in use.
II. The fact that the state of the art has been inactive over a long period prior to the invention may be an indication that an inventive step is involved if during that time an urgent need for improvement has demonstrably existed.
