Question - Dave has had a really good idea for a marketing campaign for the business he works for. Unfortunately, he is been too busy to write down the idea but he tells his boss Mary about it all the same. Mary writes up the campaign in detail, including advertising copy, photos, and scripts for the advertisements, and takes all the credit for the campaign. Dave becomes upset.
(a) Has Mary 'stolen' Dave's copyright?
(b) What is covered by copyright regarding the advertising campaign?
