Burial Structure for Human Remains and Significant Memorabilia (US 6799399)

Does this device look familiar? This 2004 patent for a burial structure bears a striking resemblance to the Great Pyramids at Giza, and even employs the same methods that were used thousands of years ago to bury the dead in ornate tombs. However, this patent makes minor changes to the design to "prevent vandalism," according to the patent summary: by building the blocks of the pyramid in a certain order, it can be sealed off entirely rather than have vulnerable spots. And, yes, that was enough differentiation to get a pyramid patented.
