Meaning
Intellectual property litigation requires clear methods to determine whether a defendant has copied a protected technology or design. To establish substantial identity proof, a plaintiff must demonstrate that the key technical features, source code, or chemical formulas of the defendant’s product are functionally identical to the plaintiff’s protected trade secret. This proof forms the core of a trade secret misappropriation claim.
Evidentiary Standard
Plaintiffs must utilize independent, certified forensic experts to analyze and compare the two sets of technology. The comparison must focus on the unique, non-public aspects of the technology rather than common industry standards.
Technical Analysis
Forensic laboratories conduct side-by-side technical reviews of the source code, schematics, or production processes used by both companies. The experts identify specific, unusual patterns, formatting errors, or hidden markers that are identical in both designs. This technical analysis often uncovers embedded forensic markers that could not have been created through independent development.
The court relies heavily on these expert reports to determine if the defendant’s technology is a direct copy of the plaintiff’s trade secret.
Judicial Test
Judges assess the expert findings alongside evidence of access to determine if the similarities are too close to be coincidental. If the plaintiff successfully presents this proof, the burden shifts to the defendant to explain the source of their design.
