Slide to unlock on mobile devices

Amazing how they patented an idea thats been around for 100+ years, isnt it?

My slide to unlock existed before yours!

A couple of things:

1) People are allowed to patent things that have already existed
2) People are allowed to trademark words that already exist, otherwise anyone could use the name "Apple"

1) no its called prior art
2) in general anyone can use the name as long as its in a non compeating industry. see apple computer vs apple music, or monster vs anyone.
