 The franchise is owned by CBS Television Studios, which now owns television properties previously held by Paramount Pictures, the studio that produced "Star Trek" for many decades; CBS Paramount continues to hold DVD rights to the TV series, and the rights to produce feature films.
The grammar of the Klingon language was created by Marc Okrand for the Star Trek franchise.
 He first described it in his book "The Klingon Dictionary".
 It is a nominative–accusative, primarily suffixing agglutinative language, and has an object–verb–subject word order.
 The Klingon language has a number of unusual grammatical features, as it was designed to sound and seem alien, but it has an extremely regular morphology.

 In the 2009 film "Star Trek", Nimoy reprised his role with Zachary Quinto, who depicted a younger version of the character, existing within an alternate timeline.

In the "Star Trek" franchise, the Klingon Empire makes use of several classes of starships.
 As the Klingons are portrayed as a warrior culture, driven by the pursuit of honor and glory, the Empire is shown to use warships almost exclusively and even their support ships, such as troop transports and colony ships, are armed for battle.
 This contrasts with the exploration and research vessels used by Starfleet, the protagonists of the franchise.
 The first Klingon ship design used in "", the D7-class battlecruiser, was designed by Matt Jefferies to evoke a shape akin to that of a manta ray, providing a threatening and instantly recognizable form for viewers.
 The configuration of Jefferies's design featured a bulbous forward hull connected by a long boom to a wing-like main hull with the engine nacelles mounted on each wingtip.
 Though a variety of Klingon ships have appeared in "Star Trek", their design generally conforms to this style.
 Most Klingon vessels were physically built as scale models, although later computer-generated imagery was used to create the models.
 In recent years, many of the original studio models have been sold at auctions.
