You can register copyright in the diary within a certain duration only if you own the rights to the work, for example, by will or by inheritance. Copyright is the right of the author of the work or the author's heirs or assignees, not of the one who only owns or possesses the physical work itself. See Circular 1, Copyright Basics, section “Who Can Claim Copyright.”
How do I protect my sighting of Elvis?
Copyright law does not protect sightings. However, copyright law will protect your photo (or other depiction) of your sighting of Elvis. File your claim to copyright online by means of the electronic Copyright Office (eCO). Pay the fee online and attach a copy of your photo. For more information on registering a copyright, see Circular 2, Copyright Registration. No one can lawfully use your photo of your sighting, although someone else may file his own photo of his sighting. Copyright law protects the original photograph, not the subject of the photograph.
Does copyright protect architecture?
Yes. Architectural works became subject to copyright protection on December 1, 1990. The copyright law defines “architectural work” as “the design of a building embodied in any tangible medium of expression, including a building, architectural plans, or drawings.” Copyright protection extends to any architectural work created on or after December 1, 1990. Also, any architectural works that were unconstructed and embodied in unpublished plans or drawings on that date and were constructed by December 31, 2002, are eligible for protection. Architectural designs embodied in buildings constructed prior to December 1, 1990, are not eligible for copyright protection. See Circular 41, Copyright Claims in Architectural Works
Can I get a star named after me and claim copyright to it?
No. There is a lot of misunderstanding about this. Names are not protected by copyright. Publishers of works such as a star registry may register a claim to copyright in the text of the volume [or book] containing the names the registry has assigned to stars, and perhaps the compilation of data; but such a registration would not extend protection to any of the individual star names appearing therein. Copyright registration of such a volume of star names does not confer any official or governmental status on any of the star names included in the volume. For further information on copyright protection and names, see Circular 33, Works Not Protected by Copyright
