General Access Solutions, Ltd. v. T-Mobile USA, Inc. and Ericsson Inc.

Summary

The United States District Court for the Eastern District of Texas denied T-Mobile USA, Inc. and Ericsson Inc.’s renewed Rule 50(b) motion for judgment as a matter of law seeking to invalidate asserted patent claims for lack of written description under 35 U.S.C. § 112(a). The court held that the jury had sufficient evidence to find that the patents’ specifications demonstrated possession of claims covering mobile wireless systems and that the verdict was not unsupported by the evidence.

Holdings

1. Claim 3 was outside the scope of the motion because the fixed-versus-mobile claim-construction dispute concerned only claims 1 and 6 of the '477 Patent and claim 16 of the '383 Patent; any requested relief as to claim 3 was therefore denied.
2. The written-description requirement does not demand a particular form of disclosure or word-for-word recitation of every covered embodiment; the specification must demonstrate that the inventors possessed the claimed invention.
3. Judgment as a matter of law was not warranted because Defendants failed to show by clear and convincing evidence that the trial record pointed so overwhelmingly in their favor that no reasonable jury could find the remaining asserted claims supported by an adequate written description.

Questions Presented

1. Whether claim 3 of the '477 Patent was within the scope of Defendants' renewed Rule 50(b) motion.
2. Whether the evidence required judgment as a matter of law that claims 1 and 6 of the '477 Patent and claim 16 of the '383 Patent were invalid for lack of written description under 35 U.S.C. § 112(a).
3. Whether the jury had sufficient evidence to find that a person of ordinary skill in the art would understand the inventors to have been in possession of the claimed subject matter, including mobile wireless systems.
