I have made a calendar wholly recapturing the structure of a very original american calendar, but changing the graphic of the numbers and inserting different photos. Should I be relaxed about it or I risk a request for damage compensation.

The calendars are considered protected by the law on copyright, like the catalogues, even though they are not expressly included in the list of protected works, list not considered wholly unconditional. Not only the contents of the calendar is protected, meaning the photographs and the particular graphic, but also the structure as a whole if original, consisting of the organization of the details according to the particular and new criteria. Therefore, in this specific case an assessment needs to be done to find how “very original” this calendar really is, as if it is so, then it is not at all sufficient to change photographs and the graphic of the numbers, as nevertheless the structure remains and could incur in the violation of the copyright. In this occurrence, not only the authors of the American calendar can demand damage compensation to the counterfeiter, but also a restrain to further production and also the retrieval of possible copies distributed on the market. If on the other hand, the calendar structure is more or less known and is not particularly original, then it is possible to make the modifications as indicated, so not incurring in any violation. On the contrary, in such a case, it would be the second author to have rights over the calendar, intended though not only on the structure, but as a whole togetherness of images and signs composing it.
