ATEN International Co., Ltd. v. Uniclass Technology Co., Ltd., No. 18-1922 (Fed. Cir. 2019)Annotate this Case
Uniclass and ATEN make and sell switch systems that allow a user to control multiple computers from a single keyboard, video device, and mouse. ATEN sued Uniclass and the customer defendants alleging infringement of its 141 and 289 patents. A jury found that Uniclass did not infringe the asserted claims and that the asserted claims of the 141 patent were invalid as anticipated (35 U.S.C. 102) without specifying which reference was the basis for its finding. The Federal Circuit reversed as to invalidity and affirmed as to infringement. The court affirmed the denial of Uniclass’s motion to declare the case exceptional under 35 U.S.C. 285. Uniclass argued that ATEN did not conduct an adequate pre-filing investigation, unnecessarily increased the costs of claim construction, drastically increased discovery costs by frequently changing counsel and infringement positions, and engaged in unreasonable litigation behavior requiring additional motion practice and leading to an expensive and disproportionate trial. The court noted that note that ATEN’s primary argument on appeal—that the court improperly gave claim construction disputes to the jury—was rejected because ATEN did not timely raise the issue below and found that ATEN’s positions were not so objectively unreasonable or exceptionally meritless as to stand out from other cases.
