Per BBC, a spokesperson for Prince Harry and Meghan Markle said that the decision to rebrand is in compliance with government rules. And because of this, they have withdrawn applications to trademark their "SussexRoyal" brand — which is currently in use for their Instagram and official website. They also won't be using their logo going forward.
On the Sussex website, they've posted details regarding their transition. One of the terms states, "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."
According to the spokesperson, the Sussexes are focusing on getting their organization ready to launch in the spring.
This rebrand may just be what Meg and Harry need to turn over a new leaf. And, who knows, maybe the new branding will gain them even more followers than their current 11.2 million on Insta.
