Stanford conference: Geron’s 345 patents and reasons for stem cell intellectual property
Perhaps more confusing than making and using stem cells are the intellectual property rules governing such use. In addition to the licenses his company has attained from the Wisconsin Alumni Research Foundation, David Earp, patent counsel for Geron, said that his company had filed more than 300 patents covering a variety of areas: undifferentiated cells; differentiated cells; methods to scale, differentiate and process cells; and ways to grow cells without blood products and feeder layers.
