I picked this up reading some blog. Why... is this even allowed? It's a paper bag with a handle.
Reading only the first page of a patent is often not very helpful to understanding what the patent or patent application is covering. In this case, the patent application isn't trying to claim all paper bags, but constructing a paper bag with 60% or greater post consumer content paper. The second thing to remember here is this is only a patent application, not an issued patent. It is common for patent applications to have extremely broad claim language. Should the application ever be granted, it is likely the claims will be narrowed considerably. As for this specific application, it doesn't seem all that novel to me, but I have no specific knowledge in the fabrication of paper bags and how difficult it is to make a paper bag out of paper with 60% post consumer content.
