&gt; rather the service is about the delivery and cost mechanism, not the actual product received.<p>Presumably they are purchasing the razor blades from Dorco and importing them.<p><a href="http:&#x2F;&#x2F;www.uspto.gov&#x2F;patents-maintaining-patent&#x2F;patent-litigation&#x2F;about-patent-infringement" rel="nofollow">http:&#x2F;&#x2F;www.uspto.gov&#x2F;patents-maintaining-patent&#x2F;patent-litig...</a><p>&gt; Patent infringement is the act of making, using, selling, or offering to sell a patented invention, or <i>importing into the United States</i> 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.<p>(If you think about it, of course importing is infringement. Otherwise, patents are worthless: anything patented would simply be made overseas, if they aren&#x27;t already.)
