WWE is always looking to lock down names when they want to use someone on television. That trend has not stopped at all.
They filed a trademark for her name in the past, but it was abandoned in December 2020, because they did not have written consent. Now, they apparently have that consent.
This trademark was filed under the “entertainment services” category in the typical way that pro wrestling names are registered.
WWE signed Duke in May 2018 and they are just getting her name locked down. It’s unclear when she might be used again, because we haven’t seen her since RAW Underground in August 2020. Duke has been working on UpUpDownDown pretty consistently since then.
