He received his first patent in 1873. Five hundred and two patents have been issued during the year 1844, including seven reissues, twelve designs, and five additional improvements to former patents, of which classified and alphabetical lists are annexed, marked N and O. During the same period, five hundred and thirty-nine patents have ex- pired, as per list marked P. Arbetet med att göra uppfinningen praktiskt fortsatte. År 1844 var processen tillräckligt genomarbetad och Goodyear fick USA:s patent nummer 3633, som nämner New York men inte Springfield. [ 7 ] År 1844 införde Goodyears bror Henry mekanisk blandning av blandningen istället för användning av lösningsmedel.
