Meghan Markle, 38, and Prince Harry, 37, were due to stop using the word ‘royal’ in conjunction with their names following their decision to step down as senior royals.
The couple officially relinquished their royal roles at the end of March and as part of their severance deal with Queen Elizabeth II, they were expected to stop using their Sussex Royal brand.
Meghan and Harry have now settled in Los Angeles with their son Archie Harrison and are keeping a low profile amid the coronavirus crisis.
While it is understood they plan to launch their new venture Archewell at some point in the future, their Sussex Royal website is still active.
Meghan and Harry had hoped to continued serving the Crown while ceasing to be senior royals but their wish to be half-in and half-out of the monarchy was deemed impossible by the Queen.
While the couple had already applied to trademark their Sussex Royal brand name ahead of their royal step down the Queen prevented them from using it in future.
In February a spokeswoman for the Sussexes confirmed they would no longer use their Sussex Royal name.
A spokeswoman for the Sussexes said: “While the Duke and Duchess are focused on plans to establish a new non-profit organisation, given the specific UK government rules surrounding use of the word royal, it has been therefore agreed that their non-profit organisation, when it is announced this spring, will not be named Sussex Royal Foundation.
“The Duke and Duchess of Sussex do not intend to use ‘SussexRoyal’ in any territory post-spring 2020.”
The spokeswoman said trademark applications that were filed as protective measures “acting on advice from and following the same model for the Royal Foundation” have been removed.
In a statement on their website, Meghan and Harry said: “While there is not any jurisdiction by the monarchy or Cabinet Office over the use of the word ‘Royal’ overseas, the Duke and Duchess of Sussex do not intend to use ‘Sussex Royal’ or any iteration of the word ‘Royal’ in any territory (either within the UK or otherwise) when the transition occurs spring 2020.”
However, their Sussex Royal website remains active and it is unclear when they intend to take it down.
The couple bid farewell to their 11 million Sussex Royal Instagram followers with an emotional message at then end of March.
Their final post on the account read: “As we can all feel, the world at this moment seems extraordinarily fragile.
“Yet we are confident that every human being has the potential and opportunity to make a difference—as seen now across the globe, in our families, our communities and those on the front line—together we can lift each other up to realise the fullness of that promise.
“What’s most important right now is the health and wellbeing of everyone across the globe and finding solutions for the many issues that have presented themselves as a result of this pandemic.
“As we all find the part we are to play in this global shift and changing of habits, we are focusing this new chapter to understand how we can best contribute.
“While you may not see us here, the work continues.
“Thank you to this community – for the support, the inspiration and the shared commitment to the good in the world. We look forward to reconnecting with you soon. You’ve been great!
“Until then, please take good care of yourselves, and of one another.”
Earlier this month a spokeswoman for the couple confirmed the name of their next venture is Archewell.
They told the Telegraph: “Like you, our focus is on supporting efforts to tackle the global COVID-19 pandemic but faced with this information coming to light, we felt compelled to share the story of how this came to be.”
“Before SussexRoyal, came the idea of ‘Arche’ — the Greek word meaning ‘source of action.’
“We connected to this concept for the charitable organization we hoped to build one day, and it became the inspiration for our son’s name.”
They added: “To do something of meaning, to do something that matters.
“Archewell is a name that combines an ancient word for strength and action, and another that evokes the deep resources we each must draw upon.”
The couple’s son Archie Harrison will celebrate his first birthday on May 6.
While it was previously thought the milestone would pass quietly, the couple are now expected to share a new photo of Archie to mark his special.
