Ex. 1001”), which issued on October 1, 2013 to Wolfe et al. from U.S. Patent

°339 Patent is currently assigned Redstone Logics LLC (“Redstone” or “Patent
Owner’). The assignment is recorded in the U.S. Patent and Trademark Office
(“USPTO”) at reel/frame 062120/0206, 064575/0934, 048373/0217, and
024009/0530.

Requester submits that this Request presents substantial new questions of
patentability based on prior art references that are non-cumulative of the
considerations that were before the Examiner during the original prosecution of the
°339 Patent. Requester also submits that this Request shows that the Challenged
Claims are invalid over these references. Requester therefore requests that an order
for reexamination and an Office Action rejecting claims 1-5, 8-11, 14, and 21 be
issued.

substantial new question of patentability based on material, non-cumulative reference

provided in Sections I and II of this Request.

Pursuant to 37 C.F.R. § 1.510(b)(2), reexamination of the Challenged Claims
of the *339 Patent is requested, and a detailed explanation of the pertinence and
manner of applying the cited references to the Challenged Claims is provided in
