- Designer Peter Swantrom on his website notes "I was very proud of this design and applied for a patent in 1997. Later I learned from Mr. Fred Sawyer, President of NASS, that a similar sundial had been patented by Mr. Lloyd Mifflin of Germantown, PA in 1867. After finding this out I then received a Notice of Allowance from the U.S. Patent Office stating that my application had been approved and that for a mere $4,000 more they would be happy to issue me a patent
