this question is related to the intriduction to the business law.

Adam came up with a great new idea for a booklet titled BrAd’s Top 10 Tips for
Successful Advertising. In addition to providing clients with some advice on
how create a solid marketing strategy, it is also an excellent advertising tool.
After each client’s first appointment with Brenda or Adam, they are provided with
a free copy of the booklet. A friend told Adam that a competitor has just started
producing a similar publication. Apart from a different cover and title, the content
is almost identical.
(a) What area of law would the publication of the competitor’s booklet come
under?
(b) If Brenda and Adam can sue the competitor for copying their idea, which
legislation would they rely on?
