Answer: Proper notice under the safe harbor provisions requires the copyright owners to specifically identify the alleged infringing materials, or if the service provider is an "information location tool" such as a search engine, to specifically identify the links to the alleged infringing materials. [512(c)(3)(iii)], [512(d)(3)]. The provisions also require the copyright owners to identify the copyrighted work, or a representative list of the copyrighted works, that is claimed to be infringed. [512(c)(3)(A)(ii)]. Rather than simply sending a letter to the service provider that claims that infringing material exists on their system, these qualifications ensure that service providers are given a reasonable amount of information to locate the infringing materials and to effectively police their networks. [512(c)(3)(A)(iii)], [512(d)(3)].

However, in the recent case of ALS Scan, Inc. v. Remarq Communities, Inc., the court found that the copyright owner did not have to point out all of the infringing material, but only substantially all of the material. The relaxation of this specificity requirement shifts the burden of identifying the material to the service provider, raising the question of the extent to which a service provider must search through its system. OSP customers should note that this situation might encourage OSP's to err on the side of removing allegedly infringing material.
