Anything more on Grip n Stik pliers?

[Northwoods]

I picked up a pair this weekend and find them really neat.  Any problem with patent infringement with better-known plierenches?
This is earlier discussion from this site.

I'm not aware of any infringement issues. 

I have one.  Only one size that I am aware of. I've always wondered about other tools in the line since it was No. 707.

Perhaps they expected the 7 1/4" model 707 to be so successful that they would follow it with a larger, heavier model, but, even with strong magazine advertisement, it didn't work out.
