WeeZuhl, Previous gelling patents invalid for obviousness. I think I read previous gelling patents by Purdue were found invalid because it was obvious to anyone trained in that field in the year 2001. It is obvious to increase the viscosity to prevent injection by syringe.

Gelling Patent No. 8,337,888 are invalid for obviousness.

WeeZuhl, so why did you bring up 50% PEO, since the gelling patent does not specify any amount of PEO?
