Hmm, I'm not sure 'bout that.
Neither am I, which is why I said I was "almost positive"
At the time of the first Star Wars film Star Trek was just a cancelled show in reruns with a cult following, and if there wasn't a Forbidden Planet, or any of the 40's 50's and 60's sci-fi we wouldn't have Star Trek or Star Wars. Lucas also admits that his films are more in line with the saturday afternoon serials of the 50's and was influenced more by those episodes than Star Trek. And might I add, if Lucas hadn't given us Star Wars, i'm more inclined to believe we'd not have had the second coming of Trek beginning from the Motion Picture (green-lit based largely on Star Wars' sci-fi success) on to the films, TNG and so forth. Just like any genre, both franchises were enriched by what came before.
Perhaps, but I imagine with todays' day & age and lack of originality, someone would have made a Star Trek movie long ago or rehashed the old series into a new series, like Battlestar G, Dr. Who, etc.
And I don't really buy Lucas's excuse, as I've seen many of those 50's space shows and movies, and most of them were way different then what I seen in Star Wars.
PS: The first use of a tractor beam can be traced to the 1931 story by E. E. Smith entitled "Spacehounds of IPC," which includes the line "Brandon swung mighty tractor beams upon the severed halves of the Jovian vessel, then extended a couple of smaller rays to meet the two little figures ..."
Ok, so there's the term, but what is meant by Swinging mighty tractor beams? What are they doing? Is it a weapon or is it more towards the Star Trek/Star Wars tool of moving things?
I wasn't referring so much toward the word itself, but both the word/thing and its purpose.
Also:
The term "cloaking device" was first coined by Star Trek writer D.C. Fontana...
Cloaking devices have also been used in many other science-fiction settings, including Doctor Who, Star Wars, Stargate and Predator.
So besides Dr. Who which aired before Star Trek in 1963 or so, at what point in the series did they begin to use the term "Cloaking Device?"..... since you say it was originally coined by a ST Writer, I'd say Star Trek was the original users of that term, where all of the other shows you listed above used the term after the fact.
Regardless of all of this, my original point in this thread was that even if a Star Trek movie trailer may have used sound effects from Star Wars, I don't think Star Wars has any place to complain. All the finer details are kinda irrelevant.
Added:
And yes, if it wasn't for past movies and shows about space through the 20's, 30's, 40's, 50's etc. there wouldn't be a Star Trek or Star Wars..... the difference is that Star Trek and Gene Roddenberry actually took the time to make it all make some sort of sense and seem actually plausable to be the future.... everything else revolved around a gimmicky storyline and a bunch of fancy eye candy effects. Star Trek is basically responsible for creating much of the technology we take for granted today (by accident or purpose) where Star Wars..... as far as I'm aware, only gave us battery operated Walker toys.
