There is a European trademark event in Belgium The Next Level: A Total Immersion Forum for Up-and-Coming Trademark Lawyers on 23rd-24th September which is organized by INTA. Unfortunately, it clashes with Suckot (the Jewish feast of Tabernacles), so we won’t be represented.
It is a shame that this type of thing happens all too frequently. I note that INTA did organize a Kosher table at the Boston Annual Meeting, so am sure it is lack of forethought and planning rather than general vindictiveness.
Since the Israel Patent Office organized a trademark seminar on the Fast of Av (see Israel Patent Authority to Hold Patentscope Seminar on Fast of Av), we can’t really complain that international organizations don’t take Jewish festivals into account.
