Conflating public domain with public knowledge risks a meaningful error. To patent something requires that you make it publicly knowable, but this knowledge would not be usable by other companies.

well... you can write a patent that is so obfuscated that the public cannot learn from it...

In such case the patent office should reject your patent claim as patent laws usually require that the description of the invention being patented should be understandable to professionals of relevant domain, who should be able to replicate it based solely on that description.

I assune you can patent part of an overall process (certainly that's the case in virtually all software patents), which could be a way to prevent others from replicating your process without explaining the whole thing, no?

While this does happen, and sometimes things obvious to a practitioner get patented, obfuscated patents are contrary to the purpose of patenting.
