Reproducibility is not impaired if the selection of the values for various parameters is a matter of routine and/or if further information is supplied by examples in the description (T 107/91).

The board in T 764/14 concluded that the skilled person was able, based on common general knowledge and corresponding routine variation of experimental conditions, to complement the information contained in paragraph [0031] of the patent in suit and, thus, to determine (possibly with some slight uncertainty but) without undue burden the surface Na baseline value for a given carrier.
