Abstract

Methane-oxidizing bacteria (MOB) or methanotrophs are a category of bacteria that rely on methane as their primary carbon and energy source. Methane is the second most abundant greenhouse gas after carbon dioxide and is comparatively far more potent in trapping heat in the atmosphere. MOBs are important microorganisms in the global carbon cycle where they play a crucial role in the oxidation of methane. The present review provides a comprehensive patent landscape on technology development using MOB. The first patent in this technology domain was recorded in 1971, with a notable surge in activity observed in 2020. A detailed patent analysis revealed that the early inventions were mainly focused on the production of various metabolites and bioremediation using MOB. In the later years, patents were filed in the area of identification of various species of MOB and their large-scale production. From 2010 onwards, consistent patent filing was observed in the genetic engineering of MOB to enhance their methane oxidizing capacity. The United States and China have emerged as the global leaders in terms of patent filing in this technology space. Precigen Inc. and Exxon Research Engineering Co., US were the top patent assignees followed by the University of Tsinghua and Calysta Inc. The Highest number of patent applications have claimed metabolite production by using MOB followed by their use in bioremediation. Methylosinus has emerged as the predominant microorganism of choice for methane oxidation applications.

Keywords: Methane, methane oxidizing bacteria, methanotrophs, patent landscape, bioremediation, oxidation applications.
