`
`·6· · · · A· · ·Well, claim 1 states
`
`·7· ·Esomeprazole not surrounded by an enteric
`

`
`·9· · · · Q· · ·Okay.
`
`10· · · · · · · And claim 1 also recites that
`
`11· ·the Esomeprazole is released regardless of

`

`

`
`22· · · · A· · ·Well, when I look at the subject

`

`
`16· · · · · · · ·If you turn to the bottom of
