Isn't the only Prime Universe facts that the novels would have to adhere to would be the fact that Romulus would be destroyed and that Ambassador Spock would be lost trying to prevent it. All other items (Picard as Ambassador, Geordi designed the Jellyfish, etc) were not part of the filmed/released movie. Would those items need to be honored?
Yes, that's what I already said. Only what's in the movie is binding. Tie-ins have never been obligated to acknowledge each other's inventions.
So what does that mean if the novels reach the end of 2387 at some future point and the licensing situation doesn't change? The ongoing 24th century storyline just ends?
I'm not the one responsible for making those decisions, nor have I discussed it with those who are. But the solution seems pretty self-evident to me: The books would just have to tell stories that weren't about Spock or the Romulans. And that's not hard. Most 24th-century Trek novels are
already about things other than Spock and the Romulans. It's a big universe with plenty of other elements to focus on. It would probably be possible to work around the edges, to allude to the destruction of Romulus or hint at a change in the status of the Romulan Empire without coming right out and mentioning the supernova directly.
After all, licensing limitations are a fact of life for adaptations. Marvel Studios movies and shows can't use the X-Men or the Fantastic Four, so they find alternatives, like focusing on Inhumans in place of mutants.
Smallville couldn't use Batman, so they brought in Green Arrow instead.
Arrow couldn't use Ted Kord, so they put Ray Palmer in his place. Nobody has to stop adapting an entire universe just because one piece of it is off-limits. They just work around it.
wouldn't it be more likely for them to just change your contracts to say "you have to adhere to what was onscreen except for the events of the Abramsverse"?
Of course not. We have to adhere to what's onscreen, period. We may not be able to mention every part of it, but that doesn't mean we get to contradict it. Some things just have to be avoided.
I mean, it's not like there's a law that forces a company to make its tie-in writers adhere to everything, it's Paramount's choice to make that the agreement. If Paramount wanted, they could say you had to adhere to "Mudd's Women" and specifically ignore the entire rest of the universe; they own it, and they get to say what you have to adhere to and what you don't.
The company formerly called Paramount Television is now called CBS Studios. CBS owns
Star Trek and licenses its tie-ins. The company that's still called Paramount Pictures licenses the movie rights to
Star Trek from CBS, or retains them through agreement with CBS, or something. I gather that the complicated rights situation between CBS, Paramount, and maybe Bad Robot (???) is part of why getting the license sorted out is so tricky.
And I suppose you're right, in a sense; as the owners of the property, CBS (or Paramount where the new movies are concerned) is entitled to rewrite the continuity however they wish, to declare a show or movie non-binding and contradict it -- like, say, the various
Highlander sequels did with their predecessors, or the way that one season of
Dallas retconned the previous season as a dream. But here's the thing -- it's the core franchise itself, the movies and shows, that has the right to do that. That's the thing that's actually
Star Trek. What we do is just an authorized imitation of
Star Trek. We're borrowing their toys. The core universe can be rewritten, but we aren't the ones who get to do that. If any part of the core franchise gets ignored, that precedent has to be set by something onscreen, something that the tie-ins can then reflect and build on.
A studio would have no incentive to authorize its tie-ins to contradict or undermine the core work, because the purpose of tie-ins, from their perspective, is to
promote the core work, to reinforce audience awareness and interest in it. These days, studios are pretty hypersensitive about making sure tie-ins and adaptations are faithful to the core work. Movie novelizations don't even get to embellish or flesh out the stories like they used to.
If you're legally not allowed to tie into the 2009 movie, then why are you still required to follow its lead?
Because it's
the actual show. The show that the tie-ins exist to promote. Like I said, it's the real deal, and what we do is just an imitation, an echo of it. Sometimes we only get to echo parts of it, but it's all just as real. You're getting it backward if you think you can treat the books as the reality and the screen canon as an optional piece of it. We have to accept the entire canon as real, even if there are parts we aren't licensed to use.
Like I said, if the canon is history, the books are historical fiction. A historical novelist may choose to avoid dealing with some part of history, may choose to write around it because it's too controversial or because some other novelist just dealt with it or something; but that doesn't mean they can directly contradict that set of historical events (assuming it's not an alternative-history novel). Trek canon is the "reality" that we're writing fiction about, so we write within its established framework.
