The illusionist wowed judges during his live semi-final this week with a trick that involved Amanda Holden's autobiography, but some critics suggested he'd been influenced by a magician, Collins Key, who appeared on America's Got Talent three years ago.
But speaking on ITV's Lorraine today, Richard said: "It's great for magic because it shows that people care and they are interested in magic.
"In terms of it being similar to some other magicians, all magicians perform very similar effects, but it's their own personal take on the effect that matters, they adapt it and make it their own.
"The roots of some of the tricks that I did on the semi-finals stem back hundreds of years and I have adapted them and made them more modern for our public and it's a bit like a singer singing her own version of a song or a dancer doing her own style of dance."
Richard's trick saw him asking judge Alesha Dixon to select a random page from co-star Amanda Holden's autobiography and a random word. The page then appeared in a glass bottle in front of Simon Cowell, while the word was burned into the book.
He previously told The Sun: "Magic is all about evolving the ideas that might have been done before with a common object. New ideas won't always be found nowadays so I'm thinking what I can do that's similar but make it more understanding and more updated. That's what magic is all about."
