Homologous telomerase gene sequences
This group of patents – three of which are owned by Geron and University of Colorado (individually or jointly), one of which is co-owned by Geron and Albert Einstein College of Medicine, and one of which is owned by Research & Development Institute in Montana – concern nucleic acid sequences and gene products of telomerase from other species. By no means does this group exhaust the species from which telomerase gene has been cloned; telomerase from other species can be found in the scientific literature.
The species represented in this group are:
- Candida albicans (US 6,541,202);
- Euplotes (US 6,093,809 and US 6,166,178);
- Schizosaccharomyces pombe (US 6,309,867);
- Mus musculus (US 6,767,719).
* – A terminal disclaimer was filed for this patent. Without obtaining the full prosecution history of this patent to reveal which patent it was disclaimed in favor of, certainty of the expiry date is not possible.
 An interference is a procedure conducted by the United States Patent and Trademark Office when multiple applications have identical claims. The purpose of an interference is to determine who was the first-in-time inventor and so deserves the patent.

 Geron has many pending patent applications on telomerase, some of which may contain claims directed to disclosure that isn’t claimed in this patent.
