I have not yet found the patent application nor an issued patent (applications are harder to find because you don&#039;t have the chain of links in actual patents that have completed the examination process)(it&#039;s also true that lots of people put patent pending and then never follow all the way through)</p><p><br /></p><p>/2/ when Hallmark went bust PCI bought their intellectual property for the small slab.

Even without a patent, the molds for the shells,&nbsp; the die for cutting labels and the sealing tooling would all have had value. Whoever bought it then either shared the wealth, licensed it or maybe passed it on to successors.</p><p><br /></p><p>Looking into this is on my list of someday projects.[/QUOTE]</p><p><br /></p>
