I think it is much more dangerous if Oracle wins. You made your DWG clone? Get sued. Made a PDF clone? Sued! Made a insertRandomProprietaryFileFormatHere clone

I think it is much more dangerous if Oracle wins. You made your DWG clone? Get sued. Made a PDF clone? Sued! Made a insertRandomProprietaryFileFormatHere clone? Sued! Made a Wine, DOSBOX, Mono, any other sort of compatibility layer? Sued!!! If Oracle manage to reverse and win this, it means that Oracle, Microsoft, Adobe, Autodesk and Apple will just bash everyone else (including Open Source stuff) to oblivion.
