Prince William, Prince Harry and Duchess Catherine have applied to trademark the Twitter hashtag #stopspeaksupport.
The royals want to trademark #stopspeaksupport to use on social media, which they hope to use to encourage people with mental health issues to speak up about what they are going through and also for everyone to offer support to each other.
The trio have been huge supporters of mental health with their Royal Foundation campaign called Heads Together.
They recently launched a £2million digital mental health scheme, "a start-up for digital mental health innovation" to help improve mental health in the UK, following the success of Heads Together.
Prince William said: "I feel like it's exam results day. This also shows that support at home is quite key, isn't it? At the beginning, we were trying to understand why at home people weren't sharing some of their problems. If we've at least made a big impression there we can work on the wider societal aspects. But I think it all has to start at home.
"If you can't even have a conversation with your loved ones, there's no way you're going to go to HR at work.
"The only thing, trying to extrapolate the data from this, is that these individuals who have spoken have probably got a reasonably good support network around them.
"Are we missing a whole set of people who have either been in care or who have had very bad experiences at young ages, who have bad mental health already? How do we affect that demographic?
"You'd struggle to find a parent out there who wouldn't want the well-being of their child to be taken care of at school."
