There is another unclaimed field; cemetery intellectual property. Patent rights on unique means and methods of designing, managing, operating, etc cemeteries. A quick search of the US Patent office yielded 314 existing patents mentioning "cemetery" and 3,034 existing patents mentioning "burial"; digging deeper one will find that most of these patents are individually owned. I have an under-utilized patent program that targets and organizes similarly subject matter patents into small groups, whereby they are then leveraged for royalties. All you need are a few broad patents to literally exclusively control the field. Another fun program to possibly explore is to gather up a couple of dozen key patents in this industry and become the foremost depository of patent holdings in the industry. It is not far fetched to envision quickly turning this patent depository into a revenue generator for KCA of several millions of dollars a year. If the U.S. death care industry is a $30B/year industry, the patent royalties generated by this industry could be 5% or $1.5B/year
