Columbia University has presented a declaration to the Federal Circuit, suggesting that Quinn Emanuel Urquhart & Sullivan LLP may have misrepresented facts related to a key witness’s refusal to testify. The witness, a former computer scientist at Norton Lifelock Inc., is at the center of the university’s $600 million patent case in a Virginia federal court. The case has been ongoing for a decade, and this new revelation could have significant implications for its progression. For more details on this development, visit Law360.
