For those that don't know, a long time ago Josh Duck built an HTML Periodic Table that actually resembled the periodic table. It got taken down, because someone else made another HTML Periodic Table (with clearly different organization and a very different look), and then she claimed that Josh Duck's very different periodic table was infringing on her copyright. She even went as far as to claim that he somehow even intercepted her emails to steal her ideas, and even alleged that Josh Duck and another guy who made a similar HTML Periodic Table were in kahoots because they were in the same country (Source: https://i.imgur.com/sthuEd8.png)!

By making this table look nothing like the periodic table of elements (or like the ones that people were sued over), I think the creator should be able to avoid being sued by anyone trying to make a quick buck.
