User blog comment:SS4/Level-5 is being sue by Sega!!!/@comment-4525039-20121211132541

There is some hope yet.

A touch screen mechincs is need for every DS games, so every company has the rights to use the DS touch screen in anyway(especially Nintendo) Also a user also point out Nintendo using the same mechnics saying that Legend of Zelda games also used the same thing, Yet why did Sega sue Level 5 instead?(This could be because Nintendo is the company that made DS so they cannot win against it).

Another good point is that Level 5 have been using the Nintendo's support on making these game, I hope that Nintendo will support Level 5 as well.

Their is a likely chance that Sega's claim will be rejected, but if that was the chance they might seek royalties.(Which I may have to look up :P)

And here is one of the quotes that was said regarding the situation

"Is touch screen too essential to the Nintendo DS console that no one company(What about Nintendo, the guys who actually made the DS) can claim patent ownership".
