Assessing the Validity of the Copyright Registration

In order to register a computer program for copyright, the author must submit a representative portion of the program source code as part of the registration application.  DisputeSoft can examine this “deposit copy” to determine whether the code is a bona fide copy of the registered work or whether the code contains modifications made after the work’s date of creation.  Failure to provide an actual copy of the software source code as it existed at the time of its creation would render the copyright registration invalid and, therefore, unenforceable in a copyright infringement lawsuit.  DisputeSoft’s techniques for determining the validity of a copyright registration have been published in IP Today and have been discussed by the Eleventh Circuit.

Investigating Claims of Literal Copying

In copyright infringement cases in which the plaintiff alleges that the defendant has copied the source code of the copyrighted work, an expert is needed to compare the source code of the allegedly infringing program to the source code of the copyrighted program.   As programs typically contain thousands of lines of code, such a source code comparison can be a daunting task.  However, DisputeSoft has developed proprietary software tools that we regularly employ to significantly streamline this analysis, allowing for efficient and effective comparisons of programs of any size.

Investigating Claims of Non-Literal Copying

In addition to claims that the source code itself has been copied, the plaintiff may also claim that the “non-literal” elements of its copyrighted program have been copied, such as its overall structure, sequence and organization.  In such cases, DisputeSoft can conduct an “abstraction-filtration-comparison” (AFC) test to analyze the degree of similarity between software elements other than actual source code.  The AFC test requires first identifying various levels of abstraction from the source code that would still qualify as copyrightable expression, filtering each level of abstraction to remove any content that is not deemed copyrightable, and finally comparing the remaining expressive content in each program to determine whether it is substantially similar.
