If you don't have new grounds to add, you may as well
copycat. On September 4, 2019, the PTAB denied Microsoft's
petition requesting inter partes review ("IPR")
of U.S. Patent No. 7,167,487 ("the '487 patent");
furthermore, the panel also denied Microsoft's motion to join
its IPR to another IPR over the same patent filed by Apple. See
Microsoft Corp. v. UNILOC2017LLC, Case
IPR2019-00744, (PTAB, Sept. 4 2019) (Paper 11).
The '487 patent, which claims certain wireless network
technologies, is owned by Uniloc 2017 LLC, who has filed
infringement actions against many well-known cellphone
manufacturers. In late 2018, a group led by Apple, including LG and
Samsung, filed an IPR petition to review the patent. The PTAB
instituted the IPR in June 2019. In March 2019, Microsoft filed its
own IPR petition to review the '487 patent with essentially the
same arguments.
