My guess is the “Pokemon Box Storage” system since palworld stores pals in a palbox.
US Patent for Content data holding system, storage medium, content data holding server, and data management method Patent (Patent # 11,998,838 issued June 4, 2024) - Justia Patents Search

A server includes a content storage medium configured to store content data of content usable in different types of games up to a first upper number, and a management information storage medium configured to store valid period information of a right to use an extended function concerning the content data The server, in case that a right to use an extended function is valid, sends the content data to an information-processing device or receives the content data from the information-processing device, and stores the content data in the content storage medium up to a second upper number larger than the first upper number. The server, in case that the right is invalid, performs at least one of transmission of the content data to the information-processing device and reception of the content data from the information-processing device, in a restricted manner as compared with a case where the right is valid.

In the “other references” they link to the bulbapedia article for Pokemon box so I figured thats what the whole thing was about, but yeah it does read like accessing data on a server
