RE: Preliminary response PTAB25 Feb 2021 18:01
Great work, Hawi. Borac's comments are spot on. I am not a lawyer or a scientist. Nor do I know what I do not know. I can however tell the difference between as sound argument and a specious one. Nanoco and it lawyers have shown that Samsung's IPR institution petition is unjustified and that its claims against Nanoco's patents are a mishmash of unrelated prior art and misleading statements.
As Nanoco's response states:
"Notably, at the time of Nanoco’s invention, Petitioner [Samsung] was still trying to solve the problems associated with producing cadmium-free quantum dots, but they were not having much luck. Petitioner was able to create cadmium-containing quantum dots, but not cadmium-free ones. Indeed, Samsung’s research lead, Dr. Eunjoo Jang, expressed publicly that Samsung found developing cadmium-free quantum dot technology “to be quite a challenge.” Ex. 2005, at 3 (Quantum Dot Artisan: Dr. Eunjoo Jang, Samsung Fellow). As she further stated: At first, we could not even imagine a Cd-free quantum dot, but in Samsung’s commitment to being a globally responsible manufacturer, the vision was to make it work. I was able to relatively quickly complete a cadmium-containing quantum dot, but I wanted to do something that no one else had. So, I worked another three years on Cd-free quantum dot. "

"Case No. IPR2021-00186 U.S. Patent No. 8,524,365 35 1001 at 5:28-29. Previous methods were unable to produce commercial quantities of high-quality quantum dots, while the claimed cluster-assisted method was—even for the notoriously difficult cadmium-free quantum dots. VI.CLAIM CONSTRUCTION Claims in an IPR are construed under the claim construction principles set forth in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc); 37 CFR § 42.100(b). “Petitioner does not believe any claim terms need to be construed to resolve the prior art issues presented” in its petition. Petition at 19. A.Molecular Cluster Compound The term “molecular cluster compound” appears in all asserted claims of the ’365 patent, and is described as being an “important feature of the invention.” Ex. 1001 at 5:5-9. Because of this importance, the patentee chose to expressly define the term to ensure its clarity. The ’365 specifications states: ‘Molecular cluster’ is a term which is widely understood in the relevant technical field but for the sake of clarity should be understood herein to relate to clusters of 3 or more metal or nonmetal atoms and their associated ligands of sufficiently well defined chemical structure such that all molecules of the cluster compound possess the same relative molecular mass. "
Nanoco's response makes a strong case that 'terminology' used in its patents, such as "molecular cluster compounds" and "seeding", are core components of its patents and that their defintions must not be ignored.
