I should say "reference" rather than "rip off".  What I mean is that it is clear, by JJ Abrams own admission no less, that he grew up a fan of Star Wars, but never watched the original Star Trek.  So, when someone says that the trailer for Force Awakens looks no different than the Star Trek reboots, it's because they are all directed by Abrams.  While he inserts characters names and places from Star Trek, his movies invoke far more memories of Star Wars than the source material he is supposed to be utilizing.

Here are similiarities that harken back to memories of Star Wars, and not Trek:

Leonard Nimoy's first appearance in the film as "Old Spock" coming out in a hooded robe to ward off a monster attacking Kirk lying on the ground is a literal recreation of Ben Kenobi coming out in a hooded robe to ward off the sand people from attacking Luke Skywalker lying on the ground.

Nero's ship blows up Vulcan, Death Star blows up Alderaan

The Federation officer uniforms from Into Darkness are carbon copies of Imperial officer uniforms

This one was pointed out by someone else:

Kirk and Khan propel towards a tiny shaft located on the admirals vessel which has a slim/none chance of success. This scene is very much like the thermal exhaust port of the death star which required pinpoint accuracy to succesfully destroy the space station. Ofcourse Kirks targetting computer in his helmet is destroyed halfway through which strongly ressembles Luke's decision to turn his off. The dialogue in this scene is almost identical in its flow to the one in star wars between rebel command and Luke(excluding any force related business)

Well, we'll see soon enough. People aren't going to like this because Lucas isn't making it. I'm just going to say it right now though, George Lucas is a Hack. The star wars universe is cool, but based on my knowledge, George Lucas is responisble for almost every stupid part of all 6 movies. 

So, no rip-offs then? Just references? I also think you need to look up the meaning of carbon copy. The Federation officer uniforms look like real world Navy uniforms exception grey.

The whole point of my comment stands true.  Aside from the character names and places, JJ Abrams Star Trek reboot resembles Star Wars far more than the source material he was supposed to be utilizing.  Abrams flat out admitted to being a lifelong Star Wars fan while never having seen an episode of Star Trek.  So, when a poster comments that the Force Awakens doesn't look any different to him than the Star Trek reboot.  It's clearly because while directing the Star Trek reboot, Abrams repeatedly went to the Star Wars well.  There is a reason why people refer to the Star Trek reboot as Abrams' audition for filming Star Wars.  But, thanks for having me explain it again.

Well, point made. It still looks the Star Trek movies though with the disadvantage of not being able to do good fights.
