Update: Ubisoft has told CVG that it is working to reinstate its Watch Dogs trademark after a "fraudulent Request for Express Abandonment" was filed last week.
With outright cancellation highly unlikely, such a move would appear to suggest the firm will grace the open-world hacking game with a new title, although a simple administrative error also cannot be ruled out.
CVG has reached out to Ubisoft for comment.
In mid-October, a month before the game's planned release, Ubisoft delayed all versions of Watch Dogs until spring 2014.
"Our ambition from the start with Watch Dogs has been to deliver something that embodies what we wanted to see in the next-generation of gaming," the company explained at the time. "From the beginning, we have adopted the attitude that we will not compromise on quality.
"As we got closer to release, as all the pieces of the puzzle were falling into place in our last push before completion, it became clear to us that we needed to take the extra time to polish and fine tune every detail so we can deliver a truly memorable and exceptional experience."
