At present, all laws dealing with the protection of intellectual property rights have been consolidated under Republic Act No. 8293.
Infringement of a copyright is a trespass on a private domain owned and occupied by the owner of the copyright, and, therefore, protected by law. Infringement of copyright, or piracy, which is a synonymous term in this connection, consists in the doing by any person, without the consent of the owner of the copyright, of anything the sole right to do which is conferred by statute on the owner of the copyright.
