I agree with you - interlocking discs have been around 50+ years as toys, and the racquet game involving feathers is pretty much a basic badminton shuttle cock (older readers will remember they were originally made of feathers before plastic became common!).

While legally you might be able to get away with reinventing old ideas and copyrighting them, it doesn't sit morally well with me!

I can raise it to 70 years, with a toy from the 1950s, "Dis Kit".

I had a mid-20th-century version as a child, which I think was originally my mum's toy when she was a child. They did have a tendency to fall apart — they were probably cut from a sheet rather than injection moulded. The small improvement to make them "click" together seems fine, but it's a bit rich to then rant about others selling similar toys.
