The second image is a screenshot of the trademark registration, it's definitely real.
As for the ratings, you need a bit of context there. Ultraman Ginga aired in the same time slot as Ultraman Retsuden, which is basically just reairings of old episodes, so its ratings have always been low. Ginga wasn't likely to do much better.
Financially speaking, last year was the best Ultraman has had as a franchise in quite some time. Granted, this is still nowhere near Sentai or Rider, but it saw a marked improvement.
