And you're posting it here because...why?

If you think there's a legal issue, this, obviously, isn't the forum.

If you want to tell people "I had this idea first!" this also isn't the forum; you're either wrong, or are pointing to the wrong thing (patents aren't particular readable or understandable); show us the thing you made.

Because I am excited that this idea got turned into a viable product. And what is wrong with sharing the excitement with my fellow nerds including the fact that I had this idea first? It is all about execution and kudos to stripe for taking this idea forward and turning into a viable product.

Then perhaps a comment along the lines of "This is really neat! I'm so glad to see someone else doing this; I originally patented something akin to it and then (never used it/did and here's the thing I built), and it's awesome to see continued development in this area".

As it is, it's not clear what your intent is (hence my question). You aren't congratulating them. You aren't expressing excitement. To your credit, you also aren't claiming they're infringing, though it begins to approach it.

Gumroad had this since 2011, 5 years before you filed your patent.

This is a good forum for it since it is for showing new products.

If this violates a patent, I definitely want to know.

If it doesn't, then there will be no problem, right?

Did you look at the patent? Did you understand it? Do you have the legal knowledge to both understand if the patent is valid (since plenty have been overturned in the past), and that this in fact violates it?

If not yes to all of those, the comment hasn't helped illuminate you in any way.
