There are several emerging technology clusters in the induced pluripotent stem cell (iPSC) space. Simon Elliot and I conducted a patent landscape analysis focusing on issued U.S. patents and pending applications. We found several geographical clusters and a trend in the development of the technology away from the use of genetic transforming factors. A brief report on our analysis was recently published on line - “Induced Pluripotent Stem Cells: A U.S. Patent Landscape Analysis.”
This report is interesting not only from a patent analyst’s perspective of tracking the evolution of IP in a particular technology, but also because it shows a clear evolution of the technology and processes for achieving the same result using different techniques.
