StemCells, Inc. has spent more than a decade systematically assembling one of the broadest IP portfolios in the world in the field of stem cell biology and related technology.
Intellectual Property Our patent portfolio consists of dozens of US patents, hundreds of foreign equivalents and active patent prosecution in over 14 distinct patent families claiming different types of stem and progenitor cells, cell culture media, stem cell research tools and techniques, and similar technologies. Our comprehensive patent portfolio includes seminal technology in cell biology including three patents identified by Nature Biotechnology as being among the five most fundamental neural stem cell patents as well as four patents identified as being among the top 20 most significant patents in stem cell research.1 We have also identified numerous protected trade secrets, especially in the area of cell manufacturing, and have a growing list of registered trademarks, especially to support our commercial sales of SC Proven® products.
While many of our patents were exclusively licensed from world-leading stem cell researchers and their institutions, a substantial number of our patents were homegrown, with StemCells scientists as named inventors. Key among these are various antibody enrichment patents and our patents claiming the use of leukemia inhibitory factor (LIF) to improve the proliferation of neural stem cells.
