Are the "Indoraptors" actually confirmed or are they just fan rumors?

The most info we have on Indoraptors is that the word "Indoraptor" has been patented by Amblin entertainment. It's not confirmed that it will appear in the Jurassic World sequel, just speculation based on the patent.

And JW and JW:FK producer Frank Marshall called the Indominus Rex a Indoraptor in a tweet.

Just that alone isn't strong evidence but since Amblin Entertainment trademarked the name Indoraptor it really seems to be likely.

Jurassic Park Fan For LIFE,

Yes, I don't think Amblin Entertainment would go through the trouble of trademarking unless they are using it in a future film.

Maybe It's comfirmed
