If I understood correctly, the empty lists in your data are essentially the separator. You can try this:

from itertools import groupby

def flatten(lst):
	for i in lst:
		if not i: yield []
		elif isinstance(i, list):
			for j in i: yield j
		else: yield i
            
OUT = [list(g) for k, g in groupby(flatten(IN[0]), key=lambda x: not x) if not k]
