U.S. Federal Circuit Court of Appeals Overturns AT&T/Nokia Patent Infringement Ruling (United States)
米連邦巡回控訴裁がAT&T/Nokiaの特許侵害判決を覆す（米国）
The U.S. Court of Appeals for the Federal Circuit overturned a $166.3 million patent infringement judgment against AT&T and Nokia by Finesse Wireless over wireless interference suppression technology, citing misinterpretation of expert testimony and invalidating the damages award. The court took issue with the reliance on expert testimony based on a misreading of Nokia's technical documents, ordering a retrial due to insufficient evidence. The reversal of the massive damages award will impact the telecommunications industry.
無線混信抑制技術をめぐり、フィネス・ワイヤレス社がAT&TとNokiaを訴えた約1億6,630万ドルの特許侵害判決について、米連邦巡回控訴裁は専門家証言の誤解釈を理由に判決を覆し、損害賠償も無効とした。同裁判所は、Nokiaの技術文書を誤読した専門家の証言に依拠した点を問題視し、証拠不十分として差し戻しを命じた。巨額の賠償金が取り消されたことで、通信業界に影響を与える。
