Can we not agree that the above cited patent was submitted by agents of Hughes Aircraft Company (now Raytheon Corp) in March 1991 and they were seeking to protect their rights to the use of the above detailed technology to be used in future efforts to mitigate global warming . . .
Well Mick . . . will you agree with the above statement?
It's a real patent for "Stratospheric Welsbach seeding for reduction of global warming", I would agree that far.
However I'd take some minor issue with your wording, which seems to suggest they intended to use it later. More likely they thought that someone might use it later, so it would be worth something.
And I think that patent has also expired.
