In IPR2017-00858, defendant petition for review of Claims 1–3, 9, 10, 18–22, and 26–30 of the
’688 Patent. See Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1367 (Fed. Cir. 2021).
The Patent Trial and Appeal Board (“PTAB”) determined that Claims 1, 2, 9, 10, 20, 22, 27, 28,
and 30 are unpatentable. See id. at 1368. The PTAB further concluded that defendant had not
shown that Claims 18, 19, 21, 26 and 29 are unpatentable; defendant appealed from that ruling.
Id. at 1368–69. The Federal Circuit affirmed the PTAB’s decision with regard to the claims that
were deemed unpatentable, but reversed and remanded for further consideration with respect to
Claims 18, 19, 21, 26, and 29. On remand, the PTAB again determined that defendant had not
demonstrated the unpatentability (or obviousness) of Claims 18, 19, 21, 26, and 29; defendant
has appealed this decision, and an opening brief is due on August 11, 2023.

In IPR2017-01928, defendant challenged all 24 claims of the ’229 Patent. 8 F.4th at 1369. The
20 PTAB initially concluded that defendant had not established that any claims were unpatentable.
Id. The Federal Circuit reversed and remanded for further proceedings as to Claims 1, 2, 9–17,
21 and 21–24 of the ’229 Patent. See id. at 1370–76 & 1381. On remand, the PTAB determined
that Claims 1, 2, 9, 11–17, and 21–24 of the ’229 Patent are invalid as obvious in light of the
prior art. Neither party has appealed, and the IPR process had been completed. Claims 3–8, 10,
22 and 18–20 of the ’229 Patent have survived defendant’s IPR challenge.
