Adoniram was a skilled mechanic and duplicated the original wooden version. It performed better because no splinters of wood impeded the passage of the cloth. Arrowsmith had no interest patenting the sewing machine then and had decided to postpone that step for a later time. He gave as reasons for not procuring a patent that 1) he was busy with other businesses then; 2) the expense of getting the appropriate drawings and paperwork together to register a patent was more than he could afford and; 3) the difficulty of introducing the new sewing machine into public use, saying it would have cost two thousand () or three thousand () dollars to start the sewing machine business. Had he seen the newspaper article titled Sewing by Machinery of December 1835 and January 1836 that was in many nationwide newspapers he may have applied for a patent right away, because it said that a mechanic of Rochester had invented a machine for making clothes which would thereafter take the place of fingers and thimbles. Hunt did not seek a patent for his sewing machine at the time because he worried it would create unemployment with seamstresses. History records show that his wife and daughter advised him against marketing his sewing apparatus. Hunt's daughter Caroline operated a corset-making shop with twelve seamstress ladies and was watching out for their interest and thousands of other seamstresses. This ultimately led to a court case in 1854 when the lockstitch sewing machine concept was applied for by Elias Howe in a patent application. Hunt submitted his initial application for his 1834 sewing machine on April 2, 1853. Records at the Supreme Court show Hunt's invention was made before Howe's machine and the Patent Office identified Hunt's preexistence but it did not issue a patent to him for this. The reason was because he had not filled out the proper paperwork for a patent before Howe's paperwork application and had abandoned the design experiment of the 1830s. Hunt acquired public acknowledgement for his invention, however Howe's official patent remained lawful because of the technicality of the timing of the paperwork. Isaac Singer arranged to give Hunt $50,000 () in installments for his sewing machine design in 1858 in order to clear up the patent confusion about sewing machines, but Hunt died before Singer was able to consummate the agreement.
