Skimming that patent, I see little indication that you solved the actual practical problems with making something like this; you wrote down the problem statement, not the solution. This should not have been granted a patent.

When you file a patent the patent attorneys tell you how critical it is to do so.

When someone infringes a patent, especially if you’re not commercializing your patent, the patent attorneys tell you, “wow, that looks really tough.”

It’s a big company game at this point, in general, or you’d need something that drives an immense amount of value before the patenting seems worth it, as far as I can tell.

Did you file for a patent in Japan? Foreign countries are not bound by United States patents; U.S. patent rights only apply within the United States.

>Pretty much all [...] are being infringed at this point.

So, funny you say that. You know those AI companies that seem to have really good training data...

Good. Patents should not reward people for simply being the first to have an idea that others can easily discover independently.

When I wanted to file a patent, the attorneys told me it was only good as my ability to enforce it, which really means how much money I have vs the other guy

I learned that lesson too. But I also learned that you get what you pay for in terms of the patent attorney's skill in crafting claims.

They are pretty inarguable prior art for anyone who wants to compete with TDK.
