No. So why bother? Registration provides you with an automatic presumption of copyright ownership and validity. It can be used to sell or license the copyright. Also if a legal dispute occurs, you do not need to prove ownership (a sealed self-addressed stamped envelope may not be enough) etc . . .
Your opponent has the heavy burden of proving that your copyright is invalid. During the legal dispute for instance, if you have a registration, your opponent cannot raise ignorance of your rights as a defence.
Furthermore, if any or part of your company’s success depends on its intellectual creativity capable of copyright protection, without a proper intellectual property protection strategy, your company’s existence may be short-lived. Lastly, independent research has shown that ownership of registered intellectual property significantly increases the market value of a company.
