`Re:
`
`RAI Strategic Holdings, Inc. v. Altria Client Services LLC
`Case No. 1:20-cv-00393-LO-TCB (E.D. Va.)
`
`Dear Max:
`
`Plaintiffs RAI Strategic Holdings, Inc. and R.J. Reynolds Vapor Company (“Reynolds”)
`hereby stipulate that, if the Patent Trial and Appeal Board (“PTAB”) institutes the pending inter
`partes review petition in IPR2021-00725 challenging the patentability of claims 1–4 and 7 of
`U.S. Patent Number 6,803,545, then Reynolds will not pursue as to the challenged claims any
`ground raised or that could have been reasonably raised in the IPR in the above-captioned
`litigation, 1:20-cv-00393.
`
`To avoid any doubt, if the PTAB declines institution of IPR2021-00725, Reynolds
`reserves the right to pursue these invalidity grounds in the parallel litigation.
`
`Very truly yours,
`
`David M. Maiorana
