Fatpipe Networks India, Ltd. v. Xroads Networks, Inc., No. 2:09-CV-186 TC DN, 2012 WL 192792 (D. Utah Jan. 23, 2012)

Key Insight: Where defendant claimed infringement based on alleged testing of defendant?s devices but claimed that no testing documentation was created and where, upon a neutral third party?s examination of the relevant devices, it was revealed that two key logs were missing expected messages and reflected abnormal device behaviors that plaintiff was unable to explain, the court held that defendant was prejudiced by plaintiff?s failure to protect and preserve the logs and the resulting inability to verify purported testing and thus ordered that all evidence of plaintiff?s testing of the devices would be precluded from introduction to the record or other use and ordered plaintiff to pay defendant?s expenses associated with the sanctions motion

Nature of Case: Patent infringement

Electronic Data Involved: Log messages, evidence of testing
