One interesting thing to me, is that it is pretty clear that the kik lawyers pretty dramatically over enforced their trademark.

For those who don't know, the purpose of trademarks is to prevent customer confusion; essentially we don't want people to be able to sell cheap knock-offs of someone else's thing without the general public being able to easily distinguish between them. In practical terms, trademarks are "scoped" by their "goods and services" declarations.

For example, Apple the device manufacture[1] and Apple the record label[2] could both be trademarked because they had non-overlapping goods and services declarations... until iTunes started selling music[3].

If you look at kik's trademark application[4], you can clearly see that the trademark is limited to chat/media consumer applications, a pretty obvious over enforcement.
