This document discusses different mechanisms for intellectual property protection, including copyright, patent, and trade secrecy laws. Copyright protects the expression of ideas but not the ideas themselves. It applies to source and object codes but there are issues around modifications. Trade secrecy laws allow companies to keep information secret to maintain a competitive edge, such as by using non-disclosure agreements. Trade secrecy was more applicable during Bingo's software development but not once the software was released. Patent provides the strongest protection by giving inventors exclusive rights over novel and non-obvious inventions.
