Cytori does actually that what is described above and also states so as can be read in this picture:
An absolute mix of legal protection through patents etc, secrecy- know how- and economics, entry barrier high due to development cost to gain that know-how. You can download the "barriers to entry" barriers_to_entry.pdf784.83 KB02/02/2012, 16:20
In respect of the traditional IP rights i.e. Patents, lets have a look what the experts have to say about that theme:
What exactly are patents and patent rights registered with the USPTO and abroad?
The following slides are from an IP-primer that you can download ip-primer-holman.pdf318.51 KB02/02/2012, 19:41 if you like and gives an overview- from this primer two slides-
Claims can be from three major categories as stated above- composition of matter, method/process and machine/apparatus. Its important to realize that with the "raw materials" of cell tech- i.e. the cells themselves, ONLY THE USA allows composition of matter claims. All over the "rest" of the world this is NOT recognized. The recent EU decision on ESC´s kind of confirmed that although for different reasons. Than again -as example- treatment of cardiac disorders with ADRCs in France can be patented i.e. a process and also the machine to use in that process i.e. Celution.
This leads to the impressive IP portfolio that Cytori possesses at present and will be extended in due course when the patent applications are through the funnel- (a "cut" a Cytori slide in two parts to make it better legible)
