In common language the Genitive of the substantival possessive
pronoun is not used. There is another form of a possessive
that could be used (der unsrige, die unsrige, das unsrige),
but it sounds really antiquated. If you want to form
a Genitive of unser
it is mostly done like in English.
Das
ist der Schlüssel von unserem (Auto
etc.).
This is the key to ours. (car etc.)
Example:
die Schachtel (= box) possessed object => feminine,
singular
Ich sehe
meine, aber unsere nicht.
I see mine but not ours.
Example:
das Kleid (= dress) possessed object => neutral,
singular
Du kannst
mit unserem hingehen.
You can go in ours.
Example:
die Häuser (= house) possessed object =>
neutral, plural
Ich sehe
unsere, aber ihre nicht.
I see ours but not hers.
