According to Comicbook.com, Marvel has filed trademarks for Alpha Flight, Age of Ultron, Black Panther, Guardians of the Galaxy, Irredeemable Ant-Man, Journey Into Mystery, New Warriors, Rocket Racoon [sic] and Strikeforce: Morituri.
Obviously Marvel has already has films either in the works or in the can for Guardians of the Galaxy and Avengers: Age of Ultron. While they are just about to film Ant-Man, it's been said that this film will NOT feature Eric O'Grady, the character most directly associated with the Irredeemable arc. Black Panther has long been in development and is a top choice to be one of Marvel's unannounced Phase 3 films. So, what about these other properties?
This is not the first time my eyes read Strikeforce: Morituri, so I did some digging to see if I remembered correctly that it was previously in development and found this 2011 story. At the time the film was being developed by another company, but it's possible the rights are back at Marvel and, maybe, the story that was being pushed into a film.
New Warriors, Journey Into Mystery and Alpha Flight all fall into the category of very interesting. Journey Into Mystery and New Warriors are either current or soon to be published comic series, while Alpha Flight, though a fan favorite, was canceled in 2011. With Marvel's recent announcement of their deal with Netflix and the addendum that they were shopping those series to other companies, the first thing that comes to mind is the possibility that Marvel may be developing these for series as well and, interestingly, they would all fit nicely into the Netflix model.
While it's entirely possible that this extension of trademarks could just be a yearly housekeeping procedure, we should be open to the possibility that Marvel is trying to aggressively expand its footprint in both film and TV.
