That is why on one level I am surprised by the petition. They are talking to a supercharged litigation monster and are asking it "Dear Oracle, ... We urge you to release the mark into the public domain". You know what a litigation happy behemoth does in that case? It goes asks some AI to write a "Javascript: as She Is Spoke" junk book on Amazon just so they can hang on to the trademark. Before they didn't care but now that someone pointed it out, they'll go out of their way to assert their usage of it.
On the other hand, maybe someone there cares about their image and would be happy to improve it in the tech community's eyes...
IANAL, but I don't think that wouldn't be enough to keep the trademark.
Also the petition was a "we'll ask nicely first so we can all avoid the hastle and expense of legal procedings", they are now in the process of getting the trademark invalidated, but Oracle, illogically but perhaps unsurprisingly is fighting it.
But yeah, IANAL either and just guessing, I just know Oracle is shady and if you challenge them legally they'll throw their weight around. And not sure if responding to a challenge with a new "product" is enough to reset the clock on it. Hopefully a the judge will see through their tricks.
