Sony Computer Entertainment Japan has patented the technology of restricting or blocking the use of the second hand video games. This technology will tag the game discs to the user accounts resulting in the rejection of playing the game with another user’s account.
According to Sony, other anti-second hand gaming methods such as Online Passes and passwords worked better only when the user was connected to the internet and the ability of those methods fell down upon disconnection from the internet.
The filing continues: “As a result [of the patented idea], the dealing of electronic content in second-hand markets is suppressed, which in turn supports the redistribution of part of proceeds from sales of the electronic content to the developers.”
Sony is expected to launch the next generation of PlayStation later this year.
