I don’t think this really means much. Companies love to incentivize their employees for coming up with patent ideas. This could very well be one of those ideas
They were going to be useful for my immigration visa renewal though. My L1 renewal got stuck with a request for evidence, and the lawyers thought that patents are excellent evidence of outstanding ability to the eyes of the gov. Eventually I got my green card before my L1 evidence got processed, so I didn’t get to see if that would have helped.
