>> At an earlier stage in litigation, the Obama administration took a similar position, urging the Supreme Court not to accept Google's appeal.
Did Ellison do a fundraiser for Obama as well?
The situation now is that Google won at court again. The jury found the API reimplementation was fair use. And the Federal Circuit overturned the trial court again, saying (I'm not making this up, though obviously I'm paraphrasing) "The jury trial we demanded before was invalid because this infringement cannot be fair use as a matter of law, we just forgot to tell you that earlier."
That is, the Federal Circuit is behaving badly here, effectively shopping around for a basis to force a trial court to find for Oracle. The time for principled legal arguments was literally six years ago, this is just partisan hackery.
So obviously Google is appealing to SCOTUS (they took the case this time, for obvious reasons), and the DoJ is jumping in to pick a side in the substance of the actual case, something they really didn't do earlier by requesting that the appelate victory stand.
Except you didn't actually demonstrate that, since they involve different appeals which did not present the exact same questions to the Court.
To demonstrate what you are trying to demonstrate you need to look at the two petitions and the briefs submitted by the two administrations, and see how much the two administrations agreed on whatever questions, if any, were common to the two petitions.
