Background: Endophytic fungi are taxonomically and ecologically heterogeneous group of
organisms, mainly belonging to the Ascomycotina and Deuteromycotina. Endophytes usually produce
the enzymes necessary for the colonization of plant tissues. Endophytes are able to utilize components
of plant cells without disturbing host metabolism, which is confirmed by isozyme analysis and studies
on substrate utilization. The patents related to enzymes and metabolites produced by endophytic fungi
are associated with their ecological significance. Application of metabolites and growth promoting factors
produced from endophytic fungi, in the pharmaceutical and agricultural industries, is now well established.
The patents on secretion of extracellular enzymes in vitro by endophytic fungi needed for cell
wall degradation, support the hypothesis that fungal endophytes represent a group of organisms specialized
to live within plant tissue.
Objective: This review presents the patents granted on different aspects of endophytic fungi for the last 11
years. This expresses the scenario and impact of these patents regarding significance in human society.
Conclusion: In the last few years, research and inventions regarding the different aspects of endophytic
fungi beneficial for host plant as well as for human beings have been carried out, which is supported by
the increasing number of patents granted on endophytic fungi.
