Why does this word have the registered trademark symbol ® on it?


On the weather app on my phone, the word 体感温度 has a ® next to it. Here's a
screenshot:

And here's the corresponding shot in English:

Am I correct in believing that what is really trademarked is just the English
"REALFEEL", and not the Japanese? If so, why keep the ® in the Japanese (and
presumably other languages') translation?




It is most likely a coding mistake. When products are internationalized,
strings in the code are changed depending on the locale of the user. In this
case, their template is something like

[code]

    "%s\u00AE:"
    
[/code]

where %s is the localized string. \u00AE is ®. They obviously haven't filed a
trademark on 体感温度, but rather some formula they use that is different from
actual windchill/heat index, which they named RealFeel in English.
