When you compose a song or its lyrics; write a story, article or computer programme; choreograph a dance; produce a video or a film; make a drawing or an illustration; make any artwork including taking a photograph; only you alone have the rights to copy, distribute, perform or display your work publicly.
Unlike the Registration of Trade Marks however, there is no regime for the registration of copyrights in Singapore. Hence, Copyright protection is mainly through the common law. You may sue others for a breach of copyright laws if they reproduce, perform, or copy your work without permission. Hence, like any other IP asset, Copyright may can be bought and sold or be licensed to others.
Protection of a copyrighted work depends on the type of work, but is generally deemed to start from the time of the creation/publication, and lasts for the life of the author or creator plus another 70 years from the end of the year in which the author or creator dies.
