Unlike patents and trademarks, copyrights are much less complex when it comes to defining the scope of what will be protected. Copyright applies as soon as a work product is reduced to a fixed form, and so there is no risk of loss of copyrights or inadvertent disclosure or use by another party. Copyright is obtained by simply affixing a proper notice to the copyright work (although works must be registered before suit over copyright can be brought forth in court). Thus, in the overall scheme of the intellectual asset portfolio, the major challenge of copyright protection is maintaining diligent efforts to identify and mark all publishable materials and to impose restrictions on their use consistent with the company’s intellectual asset strategy.
