Another district court claim construction reversed: Dane v. Ameritek

In a nonprecedential decision, the CAFC reversed a claim construction of the District of Minnesota. The patents at issue were 6,220,379 and 5,934,694. The CAFC found the district court was correct about assignor estoppel. Of the latter, the CAFC cited Diamond Scientific, 848 F.2d 1220 and Pandrol v. Airboss. There was a lurking issue of inequitable conduct.
