Lambeth Magnetic Structures, LLC v. Seagate Technology (US) Holdings Inc., No. 23-1335 (Fed. Cir. Sept. 17, 2025)

From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

Lambeth Magnetic Structures, LLC appeals a district court judgment of noninfringement of its U.S. Paten t No. 7,128,988. Lambeth argues that the district co urt er- roneously construed the claim term “uniaxial symmet ry broken structure.” Seagate Technology (US) Holdings Inc. and Seagate Technology, LLC cross-appeal, arguing t hat the district court erred in denying judgment as a matter of law on invalidity, because a reasonable jury could not have found the patent enabled under 35 U.S.C. § 112.
