`INVALIDITY CLAIM CHART FOR THE ’298 PATENT
`BASED ON U.S. PATENT APPLICATION PUB. NO. 2011/0099460 (“Dusija”)
`
`U.S. Patent Application Publication No. 2011/0099460 (“Dusija”) was filed on December 18, 2009 and published on April 28, 2011.
`Dusija is prior art to the ’298 patent under at least 35 U.S.C. §§ 102(a), (e) (pre-AIA). The asserted claims of the ’298 patent are
`anticipated by Dusija expressly and/or inherently or rendered obvious, either alone or in combination with other references, as set
`forth in the cover pleading for Micron’s Initial Invalidity Contentions and as further explained in the chart below.
`
`This chart is based on Defendants’ present understanding of Plaintiff’s apparent positions as to the scope of the asserted claims. By
`including prior art that invalidates the claims of the patent based on Plaintiff’s claim construction and infringement positions,
`Defendants are neither adopting nor acceding in any manner to Plaintiff’s claim construction and infringement positions.
`Furthermore, nothing stated herein shall be treated as an admission or suggestion that Defendants agree with Plaintiff regarding either
`the scope of any of the asserted claims or the claim constructions Plaintiff advances in its infringement allegations or anywhere else.
`Nor shall anything in this chart be treated as an admission that any of Defendants’ accused technology meets any limitations of the
`claims.
