The filing date is irrelevant, as I have pointed out time and time again.

3.8 Can bad faith be found where a domain name was registered before the complainant acquired trademark rights?
3.8.1 Domain names registered before a complainant accrues trademark rights
Subject to scenarios described in 3.8.2 below, where a respondent registers a domain name before the complainantโs trademark rights accrue, panels will not normally find bad faith on the part of the respondent. (This would not however impact a panelโs assessment of a complainantโs standing under the first UDRP element.)

3.8.2 Domain names registered in anticipation of trademark rights
As an exception to the general proposition described above in 3.8.1, in certain limited circumstances where the facts of the case establish that the respondentโs intent in registering the domain name was to unfairly capitalize on the complainantโs nascent (typically as yet unregistered) trademark rights, panels have been prepared to find that the respondent has acted in bad faith.
Such scenarios include registration of a domain name: (i) shortly before or after announcement of a corporate merger, (ii) further to the respondentโs insider knowledge (e.g., a former employee),
(iii) further to significant media attention (e.g., in connection with a product launch or prominent event), or (iv) following the complainantโs filing of a trademark application.

I've added some highlighting on important bits. I'm sure it is TL;DR for most. Cheers.
