Let's say we have a company called ParentCompany (www.parentcompany.com)
That company has 3 products called P1, P2 and P3 (www.p1.com, www.p2.com, and www.p3.com)
The company and each of its products have their own logos.
The company is software based and is aspiring to do business in more than one country.
What is the best way to register/copyright/trademark this company and it's products & logos?
Is it fine if we simply add "© 2011, Parent Company" in the footer of the company and the products websites.
Thanks in advance!
