Throwback: I wrote about how a copyright has value even if it's not registered. https://twitter.com/MarkJKings/status/1204574175450419200

Every time I write about copyright registration, well-meaning Twitter people jump in to add "this is only in the US" or some other clarification.

As I say, assume all my threads have asterisks. Here are the some of the important asterisks for that thread:

I'm typically writing about copyright law in the United States. Most other countries don't have this requirement that a copyright must be registered before suing.

Also if the work is not a United States work (that is, a foreign author created the work in another country), the author doesn't need to register the copyright before suing in the US.

Last year, the Supreme Court issued an important decision on copyright registration. But it doesn't affect what I wrote. I wrote a separate thread about that: https://twitter.com/MarkJKings/status/1204789634334511104

The Effective Registration Date is different than the date the copyright must be registered for the filing requirement. I wrote about that in this thread: https://twitter.com/MarkJKings/status/1209601465804681217

And if the work is published, statutory damages may be available if the registration is "within three made months after the publication of the work." But discussing "publication" of a copyrighted work needs a bunch of other threads.
