A developer of an open-source project had their EU trademark revoked after a $160M-funded company filed for cancellation, citing the developer's inability to prove 'genuine use' of the trademark in the EU. The developer had attempted to provide evidence of usage, including Google Analytics data and GitHub stats, but it was deemed insufficient. The company had previously tried to register the trademark in the US, but was initially blocked due to likelihood of confusion. The developer is now considering whether to appeal the decision or abandon their trademark altogether.
