The Prince and Princess of Wales have made a significant move toward launching their work in the US, just weeks after Kate quietly resumed work following the completion of her cancer treatment.

Prince William and Catherine have reportedly completed and submitted official documents to the United States Patent and Trademark Office in preparation for the official launch of their Royal Foundation charity in America, reports the UK’s Mirror.

The trademark application includes a reference to “healthcare services relating to mental health”, which could potentially overlap with Prince Harry and Meghan Markle’s work in the US.

“Meghan was quite shocked when she found out that Kate and William plan to do more work in America after trademarking their foundation’s brand with authorities,” a source told OK! magazine.

“Although they have made a couple of trips to the US, it’s not really part of their territory and now Meghan feels they could be moving in on her turf.”

The Waleses first lodged their initial bid to secure a US trademark focusing on mental health projects in May last year, but plans were reportedly paused amid Kate’s cancer diagnosis.

Palace sources reportedly told Tatler magazine that the reignition of the plans are nothing more than “internal housekeeping” – but it’s unsurprisingly still being viewed as a positive sign in Kate’s path to recovery.

Earlier this month, the princess announced in a personal video released by the Palace that she had officially completed chemotherapy, and was “looking forward to being back at work” and undertaking “more public engagements” when she felt able.

She’s since made her first appearance on the official Court Circular for the year, after hosting a meeting with her Centre for Early Childhood team members, and it’s understood she’s also in the midst of planning for her annual televised Christmas carol concert, which is held at Westminster Abbey.
