Federal Circuit Precedential

Category: 02 – February

  • US Synthetic Corp. v. ITC

    A claim that recites material properties to define structural characteristics of the claimed composition is not directed to an abstract idea that is patent ineligible under Section 101 when the specification clearly explains the correlation between the claimed properties and the structural characteristics.

  • Kroy IP Holdings, LLC v. Groupon, Inc.

    A decision of unpatentability in an IPR reached under a preponderance of the evidence standard cannot collaterally estop the patentee from asserting other, unadjudicated claims at the district court.

  • Trudell Medical International Inc. v. D R Burton Healthcare, LLC

    Untimely expert testimony is only allowable when there is a showing that the failure to disclose was either substantially justified or harmless.

  • HD Silicon Solutions LLC v. Microchip Technology Inc.

    Extrinsic evidence may only be used to assist with a proper understanding of a disputed claim limitation and should not be used for claim construction when it conflicts with the specification, claims, and prosecution history for the disputed claim limitation.
