It's been around for sometime, a Japanese chemical Chuggi Photo Chemical company bought the rights to the Ilford name off the receivers of Ilford Imaging in Switzerland.
Ilford did make their own version of Rodinal, Certinal, which they introduced around 1907 and discontinued late 1950s. Although Mees worked on a similar developer while at Wratten & Wainwright Kodak didn't make an equivalent Kodinol until just after WWII, made by Kodak Ltd here in the UK and never sold in the US.
