They didn't mention Panavision filming because the idiots bringing the suit are proceeding on the basis that all films are shot flat. While the aperture for an anamorphic film does cut off some information during projection, this is understood from the get-go and is never an issue when it comes to video transfers.

Keep in mind that Panavision is only a brand name now; although it used to apply to certain widescreen processes, the company's cameras are now used for all formats of shooting, flat and anamorphic (or scope as it is referred to in the industry).
