In 1855, Alphonse Poitevin improved his photolithographic process and utilized it in his studio until 1857. On October 27, 1857, for reason of poor management of business, Lemercier bought Poitevin’s studio and patent, and used photolithography in his printing house. They created a collective society for the utilization of the process. The profits were split down the middle. The society was later divided in February 1867. The use of the patent would unfortunately reveal itself barely profitable, the stress of which put the two men at odds with each other. In 1859, Poitevin began legal proceedings against Lemercier for not having put the complete title “Procédé Poitevin” on the bottom of the plates, instead putting only “P. Poitevin,” and for paying less than the full cost of the patent. The judge ruled in January 1860, in favor of Poitevin. 
Le Sérapéum de Memphis by Auguste Mariette, is one of only a few rare books illustrated by Poitevin’s photolithographic process. Le Sérapéum de Memphis describes the Egyptian collections in the Louvre originating from that famous site. In his preface to this sumptuous work, Mariette sings the praises of photolithography, of thanks to which the images are taken, without the intermediary of the pencil, directly from the monuments themselves.
