Increased digital technology and website improvements have uncovered another discovery in the story of Micajah Clark Dyer. A descendant of MCD sent the foundation the following link, a publication called the Official Gazette of the United States Patent Office. It is simply an annual publication with a synopsis of each patent filed that year.

On page 315 is Clark Dyer's patent:
