Personally, I think the Playtime Automated Companion is this thing from RESTRICTED_omnitool.mp4.
They censored the bottom with static, they're hiding the name of the device for some reason. And it could explain why the trademark was first made back in 2024, because it relates to the Omni-Hand and Omni-Chip that appear in Chapter 4.
Although it doesn't explain why one of the PAC trademarks was for plush toys...
