Outside of the very specific cases of Palworld and WB’s notorious Nemesis System, you probably can just ignore the patents and do whatever you want, many of these are filed for self protection rather than to enforce them.
Metroid Zero Mission’s Mother Brain fight is patented, it literally is about shooting the player when they make line of sight with the Brain eye, besides being utterly ridiculous to have something like this patented, you don’t see anyone going to court over this.
Nintendo patents almost every mechanic they deem noteworthy, even if they amount to a bunch of gimmicky minigames or interactions. The sanity system, as it currently exists, is very rudimentary and overstays its welcome quickly, I’d argue making something substantially better was always on the table, and that alone would’ve bypassed the patent, so long is not literally the same code or instructions I guess.
