If I had my own device/biotech company, I would do the paperwork to set up a corporation-C corp. The advantages of setting up a corporation were discussed in the lecture; you can sell shares to raise money, you can get loans more easily, limited liability, you can pay dividends, stable when shareholders leave or die. As also discussed there will be a lot of paperwork involved/administrative duties, and double taxation. As opposed to S-Corp, C corporations can have no restrictions on ownership, and C corporations can have multiple classes of stock. So C corps have more flexibility if you plan to grow, and expand the ownership or sell the corporation.
