Presumably they are purchasing the razor blades from Dorco and importing them. http://www.uspto.gov/patents-maintaining-patent/patent-litigation/about-patent-infringement http://www.uspto.gov/patents-maintaining-patent/patent-litig... > Patent infringement is the act of making, using, selling, or offering to sell a patented invention, or importing into the United States a product covered by a claim of a patent without the permission of the patent owner. Further, you may be considered to infringe a patent if you import items into the United States that are made by a patented method, unless the item is materially changed by subsequent processes or becomes a trivial and nonessential component of another product. A person “infringes” a patent by practicing each element of a patent claim with respect to one of these acts. Further, actively encouraging others to infringe patents, or supplying or importing components of a patented invention, and related acts can also give rise to liability in certain cases. (If you think about it, of course importing is infringement. Otherwise, patents are worthless: anything patented would simply be made overseas, if they aren't already.)
