The scientific literature published in peer reviewed journals is the limited source of information for most of the scientists and academicians. As neither all researches nor their technological strategies are published in papers, therefore, lots of information remains missing. The systematic patent analysis using authenticated patent database makes it possible to find out technological strategies adopted by potential researchers. In spite of that, the research gaps along with research directions in a particular research field can also be identified. The aim of present study was to analyze the patenting trends in bioremediation technologies for environmental pollutants. This analysis was based on various criteria i.e. patenting trend over time, country-wise and assignee-wise comparisons and types of technology used in various patents. The Delphion database was used to retrieve bioremediation patents filed during 1990 to 2013. Out of 443 patents, United States accounted for maximum patent publications, followed by China, Japan, Korea, India etc. Yearly analysis revealed that maximum (35) patents were published in 2005. Out of 31 patent assignees, the United States Secretary of Agriculture obtained maximum patents followed by Exxon Research and Engineering Co. Comparison among technological groups indicated that maximum patents (33%) were associated with technologies for reclamation of contaminated soil followed by wastewater and sewage treatment technologies (22%) and use of micro-organisms (20%) natural as well as genetically engineered for bioremediation of environmental pollutants. Further, identification of process/product based utility of screened patents revealed that 80% patents were directed towards processes of bioremediation while 20% were products for assisting bioremediation.
