No offense, but I think you’re just being dazzled by patent-style writing. For whatever it’s worth on an anonymous Internet forum, I’ve written patents, and litigated patents, related to analogous compression technology.
It is not difficult to write something that sounds complex and novel in a patent, but is in fact a completely obvious, generic solution that any person of skill in the art would immediately and inevitably have upon confronting a task or problem. The patent examiners are overworked, underpaid, and every patent attorney knows this. Thousands of patents are granted that should not be granted every year, because after a few office actions and responses, high-paid attorneys inevitably make it too time-consuming for the patent examiners to fight.
And while yes, sometimes tech companies steal tech, you should also be verrrry suspicious of anything coming out of EDTX by default.
