Legal Question in Intellectual Property in California

Linking, in and of itself, is not a copyright infringement since there is no actual copying involved.

However, linking can create potential liability, if the linking site creates a false impression about its relationship to the site linked, or if the link misrepresents the nature of the linked site or casts it in an unfavorable way.

Also, linking to the content from another site within a frame that contains banner ads as well as site specific content belonging to the linking site could lead to liability for selling advertising on the linking site when viewers were actually viewing the linked site instead.
