Kaufman v. Microsoft Corp.,, No. 21-1634 (Fed. Cir. 2022)
Annotate this CaseKaufman’s now-expired patent describes and claims methods for using a computer to automatically generate an end-user interface for working with the data in a relational database. Kaufman sued Microsoft, asserting infringement by Microsoft’s making and selling of its Dynamic Data product. A jury found Microsoft liable and awarded damages of $7 million. The district court upheld the verdict and denied Kaufman’s motion to amend the judgment to include prejudgment interest. The Federal Circuit affirmed the denial of Microsoft’s post-judgment motions but reversed the denial of prejudgment interest. Microsoft failed to preserve its challenge to claim construction with respect to the phrase “automatically generating,” and failed to establish that the district court erred in its claim construction or that the jury’s verdict was not supported by substantial evidence.
