Intellectual Property Law
Intellectual Property Law Questions? Ask a Lawyer
when you took the photos, did you transfer the copyrights in any manner?
was there any type of agreement?
then it sounds like you still have the copyright, I suggest you meet with an attorney to have them send a cease & desist letter to the publisher/seller of the Calendar...if it's a very small matter then you could send a letter/email on your own.
yes, you want them to stop using the photo and/or compensate you for the use. It would be better if your copyright was registered but not required at this stage (but it is required to file a lawsuit)
if you are referring to how to register the copyright, see www.copyright.gov, it can be filed online for a small fee of around $40, you just have to get familiar with the process on the website
you don't have to in order to have the basic copyrights, but you do to get the legal benefits of registration (e.g. filing federal lawsuit, statutory damages etc.)...sometimes collections of photos can be filed as a group is they are related
yes it helps to show your authorship
I would see a copyright attorney right away to consider your options and what type of C&D letter to send them
or you can try to do it yourself first and if you don't get results have the attorney do it
obviously they will take a letter from the attorney more seriously and it's much more likely to get you faster & better results
best of luck, and please rate me. thanks
