Square Enix Europe has filed a trademark for Lara Croft: Reflections in the US, Siliconera reports.
While it's unclear what the trademark filing relates to, the success of Crystal Dynamics' recent Tomb Raider reboot likely ensures there'll be more new series entries on the way.
The studio said earlier this month that the game amassed over one million players in just two days on sale. Tomb Raider also recorded the biggest UK launch of 2013 to date and has topped the UK all formats chart for the past two weeks.
Earlier this week, creative director Noah Hughes and global brand director Karl Stewart told fans the studio is looking forward to taking Lara "on new adventures".
Stewart said: "Future games will be defined by who Lara has become as a result of who she is at the end of this experience."
Hughes added: "Now that Lara is more experienced, we are excited to take her on new adventures that challenge her new strength and confidence. It is important that even as Lara grows as a character, so do the challenges she must face.
"In terms of where we go next, we cannot answer too directly, but now that Lara has survived the Island she can follow the clues that she found on the Island."
Unfortunately the pair also said Crytstal Dynamics currently has no plans for any single-player expansions, noting: "All of our DLC is based around the multiplayer experience for now."
Earlier this week, Square Enix released the first batch of Tomb Raider DLC, featuring three new multiplayer arenas. The Caves & Cliffs map pack is a timed Xbox 360 exclusive.
