Worth reading the article, but for the TL:drs and comment readers:

• A patent attorney has narrowed down the list of potential candidates that could be central to Nintendo’s lawsuit against Palworld developer Pocketpair to 28 patents.
• Out of those, one particular intellectual property describing creature-capture mechanics was labeled as a “killer patent” that would be difficult not to infringe when making a game with monster-taming elements.
• The said property is part of a recently approved patent family consisting of three more patents, all of which were approved mere weeks before Nintendo and The Pokemon Company sued Pocketpair.
