I would like to sell my own toilet paper rolls, but having done some google searches, there seems to be a lot of patents on it, many of which are held by Kimberly Klark. Is it possibly for me to buy wholesale toilet paper from over seas and sell in at home legally?
That depends on a lot,and this isn't enough information to figure that out. Infringement covers anyone who sells, attempts to sell, imports or attempts to import any infringing products, but there's more to it than this.
Which patents specifically do you think you'd infringe? Most of the basic elements of toilet paper patents expired long ago.
If you import the paper and then use it for an infringing purpose, then yes, of course, you can get sued for infringement. Where you source the paper doesn't matter.
If the paper itself is infringing, then again, yes, you are infringing.
