EXHIBIT A-20
`INVALIDITY CLAIM CHART FOR THE ’298 PATENT
`BASED ON U.S. PATENT APPLICATION PUB. NO. 2009/0327591 (“Moshayedi App.”)
`
`U.S. Patent Application Publication No. 2009/0327591 (“Moshayedi App.”) was filed on June 25, 2009 and published on December
`31, 2009. Moshayedi App. is prior art to the ’298 patent under at least 35 U.S.C. § 102(a), (b), and (e) (pre-AIA). The asserted claims
`of the ’298 patent are anticipated by Moshayedi App. 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.
