"Scientifically tested!" is the marketing term for "The tests showed it didn't work, but we won't mention that second part!"
E.g.:
"successfully flight-tested" -- didn't break or leak anything when launched into space. A brick also has these properties.
"validated across three space missions" -- a brick could be flown multiple times too, this proves nothing except that this thing is space-rated.
"protected by a portfolio of granted international patents" -- we've got more lawyers than engineers!
"accumulated more than 700 hours of on-orbit operation" -- I could say the same thing about a brick left in orbit for a month.
"multiple on-orbit activation cycles have continued alongside data analysis and characterization activities" -- we kept turning it on and off in a futile attempt to work out why nothing was happening.
"confirmed system functionality in real space conditions" -- It definitely was "on", drawing power and everything!
"several long-duration tests were conducted in which it was observed, objectively and repeatedly, that motor activation produced a measurable acceleration or deceleration of the host spacecraft." -- we got confused by atmospheric drag, IMU drift, vibrations, and other confounding factors and called the experiment a success despite a string of failures for short-duration tests.
