The Unilever owned brand has filed a trademark application with the Intellectual Property Office for the spread brand featuring pink branding with flowers and the words "summer of love" emblazoned on the logo.
Unilever confirmed it is set to roll out a campaign, but declined to reveal any details at this time.
However the new campaign could be designed to echo the infamous 1967 summer of love gathering, or play on the spread's "you either love it or you hate it" motto.
Marmite has been ramping up its marketing activity and this campaign could be a step away from the comic tone of its most recent work.
The brand rolled out a spoof ad featuring Dean Gaffney in February as part of its "neglected" series of campaigns.
In the spot, designed to remind customers not to forget the spread, a Marmite rescue team is sent in to rescue the former soap star from an embarrassing magic show.
It also set up a spoof helpline to save the world from "Marmaggedon", urging consumers to report cases of "Marmite neglect".
