Vertebrate Telomerase and Splice Variants

These patents over the hTERT gene were filed at nearly the same time as patents held by Geron, but cover the splice variants the Geron patents do not. Issued in the United States as US 6,916,642, US 6,846,662, AU 1998/82854 B2  and Korea as Patent Number 581990.   Applications are pending as US 2005/176022, NZ 501,962, Brasil P19810643-0, Canada 2,294,792, China 98808383.3, EP 04026579.5, HK 01101501.9, Israel 133830, Japan 11-508771, Mexico 000196, and WO 1999/001560.

Available under a BiOS license, which allows both research and commercial use.  Contact for more information on licensing or receiving hTERT clone under an MTA.

IP Portfolio licensable from Cambia

Cambia is in the process of implementing its new policy to maximize the public use of its work product.   To this end, we intend to a) abandon all of our patent protection over our inventions and no longer require licensing of any type, and b)  and to longer restrict use of our physical materials through materials transfer agreements (MTA).


We will simply ask that all users of technology or know-how from Cambia acknowledge our contribution to your work.  Those who wish to contribute financially are of course welcomed to do so.


This new policy will be announced publicly in due course.
