Well Good news that patent covers absolutely every variation of that compound possible. It would take me a good month to draw out all the compounds.

The application states Nitrile Derivatives and reading through it is some very advanced chemistry that I have little exposure to but basically

There is a parent compound and then if you change one of the bonding atoms or atom groups you would have a derivative. It stems from the parent compound but it is structurally different.

And again this patent is covering so many derivatives that I am in awe.
