Petitioner Taiwan Semiconductor Manufacturing Company, Ltd. filed a Petition (Paper 2, “Pet.”) requesting inter partes review of claims 1, 4, 8–11, 13, 17–24, 26–28, 43, 46, 49, 50, and 52–62 of U.S. Patent No. 8,354,726 B2 (Ex. 1001, “the ’726 patent”) pursuant to 35 U.S.C. § 311(a).
Using the disclosed distance “enhances the carrier mobility in a channel of a field effect transistor including the first gate electrode, and provides the structure applicable to miniaturization of the semiconductor device.” Id. at col. 3, ll. 11–14.
“Rather, obviousness requires the additional showing that a person of ordinary skill at the time of the invention would have selected and combined those prior art elements in the normal course of research and development to yield the claimed invention.” Unigene Labs., Inc. v. Apotex, Inc., 655 F.3d 1352, 1360 (Fed. Cir. 2011).
For an obviousness analysis, “it can be important to identify a reason that would have prompted a person of ordinary skill in the relevant field to combine the elements in the way the claimed new invention does.” KSR, 550 U.S. at 418.
Further, an assertion of obviousness “‘cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.’” Id. (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)).
