Sorry about the previous response. I didn't pay enough attention and answered incorrectly.
The current phrasing does indeed refer to the licensee's ability to file for additional rights, rather than the creator's. This doesn't seem appropriate for the project (although it should be clear that Long Tail Games won't be applying for a trademark or patent based on these designs). This contract is based on a template provided by the Arts Law Centre of Australia, which means some sections needed to be modified, and obviously this one fell through the cracks.
I will update the contract to remove this sentence. Although, for anyone who has agreed earlier, I'd like to reiterate that Long Tail Games has no interest in filing any kind of trademarks ever - certainly not for a single card.
Thanks for bringing this to my attention! The intent of the agreement is that the creator grants Long Tail Games a non-exclusive right to print this card, leaving the original creator free to distribute, publish or otherwise monetize the design in any way they want. I want to keep improving the standard agreement over time, so it can align better with that goal.
