>>2934439Impossible can't use the Polaroid process because the materials and supply chain Polaroid used was destroyed with the company's exit from the industry. When Polaroid shut down, those materials were also discontinued for environmental reasons - the chemistry was only still in production under grandfather clauses.
I'm not sure where Fuji and Polaroid stand regarding Instax, etc.(fuck, Polaroid has their own, rebranded version of the Instax Mini camera and film) - however I do recall Polaroid licensed their packfilm patents to Fuji back in the early-90s. The big lawsuit you're thinking of was actually with Kodak in the mid-80s, which Polaroid won and forced Kodak out of the instant business.
