Worlds Inc (WDDD)

[abcd12]

Worlds had asked for collateral estoppel, and if Worlds is collateral estoppeled, then the recent vacate AND remand opinion by the CAFC effective become a vacate ONLY decision (the remand for RPI determination and discovery becomes moot).

And if collateral estoppel does not apply, then RPI determination is necessary, and the PTAB may need discovery in order to address RPI issue.
