I was reading up on the Henrietta Lacks story (an interesting story unto itself) and came across this
article that was written by the author who wrote the book on Henrietta Lack and her immortal cells.
The basic gist of it is that companies are rushing out to patent human genome disease/cancer sequences and are charging hefty licensing fees to do research and testing using those patented sequences. These license fees are sometimes so much that it discourage scientists from doing further research into those areas for fear of patent violations (read: litigation).
But seriously, how can our patent system allow someone to patent something that the company didn't create/invent but occurs naturally? All they did was isolate it. On the flip side, can my family sue the disease's patent holder if I were to die from THEIR disease even though I acquired it naturally?
