In the late 1850/60s, many scientists and inventors were focused on a new field of research: the creation of the modern day paper bag. It was such a hot topic that the original designer is unknown. The three possible inventors are Margaret Knight, William Goodale, and Francis Wolle.
UNION PAPER-BAG MACHINE COMPANY v. MURPHY.
The Union Paper-Bag Machine Company, assignee of William Goodale, to whom letters-patent No. 24,734, for an improvement in machines for making paper-bags, were issued July 12, 1859, and subsequently extended, brought this suit to restrain Merrick Murphy and R. W. Murphy from infringing said letters. The respondents justified under letters-patent No. 146,774, issued Jan. 27, 1874, to Merrick Murphy.
Letters-patent No. 24,734, bearing date July 12, 1859, were granted to William Goodale, for new and useful improvements in machinery for making paper-bags, as more fully described in the specification. Patents at that date were granted for the period only of fourteen years; but the record shows that the same was duly extended for the further term of seven years from the expiration of the original term, and that the patentee, on the 14th of July, two days subsequent to the extension of the patent, by an instrument in writing, sold and assigned all his right, title, and interest in the patent to the complainants, who instituted the present suit. What they charge is that the respondents are making and using the patented improvement, the title to which they acquired by virtue of the aforesaid written assignment.
