When businesses need to raise money (called 'capital'), more laws come into play. A highly complex set of laws and regulations govern the offer and sale of investment securities (the means of raising money) in most Western countries. These regulations can require disclosure of a lot of specific financial and other information about the business and give buyers certain remedies. Because "securities" is a very broad term, most investment transactions will be potentially subject to these laws, unless a special exemption is available.
Businesses often have important "intellectual property" that needs protection from competitors in order for the company to stay profitable. This could require patents or copyrights or preservation of trade secrets. Most businesses have names, logos and similar branding techniques that could benefit from trademarking.
