I used to think so, but our resident patent attorney on FR has convinced me otherwise. Patents were loose in the 1990s but have tightened up significantly.
I don't understand how you can patent something that exists naturally (gene sequences). Perhaps they patented the sequencing technology or gene sequences that they actually spliced themselves?
IIRC, you have to prove a practical application/working model before you can patent.
"YOU, or someone you love, may die because of a gene patent that should never have been granted in the first place. Sound far-fetched? Unfortunately, its only too real."
