In what year did Margaret E. Knight secure the patent for her square-bottom paper bag machine?
Answer
1871
The specific timing of securing legal protection for the square-bottom paper bag machine is a key detail in understanding the patent dispute with Luther C. Crowell. Margaret E. Knight successfully secured the official patent for the complex mechanism designed to fold, cut, and paste paper into the sturdy, flat-bottomed grocery bag configuration in the year 1871. This date serves as the anchor point against which Crowell's subsequent application was measured, although the administrative process allowed him to secure his own patent first, initiating the necessity for litigation to reaffirm Knight's prior rights.
