Warrantee on Canon Lens Repair?

Does Canon have a warrantee on USA factory service center repairs?

I had the focus on my 50L repaired a couple months ago and now it's malfuctioning again.

I find anything on Canon's website or in my communication with the service center about warrantee info.

Speak to them

on the 2nd page of my receipt from last year it states:

"Repair Warranty Information
