Geltungsjude was the term for people who were considered Jews by the first supplementary decree to the Nuremberg Laws from 14 November 1935.
The term was not used officially, but was coined because the persons were deemed (gelten in German) Jews rather than exactly belonging to any of the categories of the previous Nuremberg Laws.
A person with two Jewish grandparents who satisfied none of the criteria (a) through (d) was not considered a "Geltungsjude" but a Mischling of the First Degree.
In contrast, while Mischlinge of the First Degree within the Old Reich were subject to various forms of discrimination, they were at least in principle exempt from deportation.
Their status as "provisional citizens" was subject of an intra-regime tug-of-war between maximalists like Heydrich (who wanted them treated like Jews) and minimalists who pleaded against "throwing out the Aryan with the Jewish blood" (such as Wilhelm Stuckart and his assistant Hans Globke).
