Ouch! I've had that happen where an idea I had got used before I could reach publication.
I was using the term "Synthoid" in VQF's first draft. Then the Aliens movie came out (I'd never seen part one at the time) and I lost that term. I switched to Synth, but that sounded too similar. In this draft I'm using Synthite, but I don't like that either. Basically I feel like I'm kicked off my term.
Slightly related, my concept of hands-free invisible computing (Buck Rogers was using terminals and Star Trek was using chest badges) which was revolutionary in the 80's has basically been stolen by real life. I totally need to release VQ before someone invents time travel and trumps Imager.
