[BC] HD Patent Fight

>As an end-user, though, I simply join you (the manufacturer) through a counterclaim, arguing that as an end user I have a reasonable expectation that the product I bought from you doesn't infringe on someone's patent.
 
Well you either join the manufacturer in the defense (if invited) or you sue the manufacturer for not indemnifying (which won't go far). A counterclaim against the patent holder would need to be that he infringed *your* patent. Unfortunately trolling isn't against the law (yet).
