On March 11, 2016, Paramount and CBS filed an amended complaint against Axanar Productions and Alec Peters for copyright infringement complaint, specifying precisely which elements of the Star Trek intellectual property that the two studios believe was illegally used without consent.
The original complaint was brought by Paramount and CBS on December 29, 2015. Axanar’s legal team filed a response on February 22, 2016 seeking dismissal of the lawsuit on a number of legal grounds. Presumably, that response is what has motivated Paramount and CBS to amend their complaint.
Please note: Fan Film Factor is taking a neutral stance regarding this lawsuit and will simply announce developments as they happen.
