What type of evidence could be significant in a copyright infringement case?

In a copyright infringement case, metadata from files that shows authorship and modification history holds particular significance because it provides direct evidence of ownership and the timeline of changes made to the work. Metadata can include information like the creation date, modification date, and the identity of the author, which can be critical in establishing whether the defendant had access to the work and if they have copied it without permission.

This type of evidence is especially useful in digital environments where works are easily shared and manipulated, as it can trace back to the original creator and validate claims of infringement. By examining the metadata, legal entities can determine the originality and authenticity of the work, reinforcing its value as evidence in legal proceedings.

While witness testimonies can also be valuable, they often rely on personal recollection and may be less objective than metadata. Sales reports could indicate financial impact but do not demonstrate authorship or direct infringement. Social media likes may help gauge popularity or reach, but they do not provide pertinent information related to ownership or the legality of copying the work. Thus, the metadata stands out as the most relevant and effective type of evidence in copyright infringement cases.
