2:21-cv-00033
E.D. Tex.Jul 17, 2024Background
- Evolved Wireless sued Samsung alleging infringement of claims 1, 3, 6, and 8 of U.S. Patent No. RE46,679 ('679 Patent).
- Samsung counterclaimed that the asserted claims were invalid for lack of written description (35 U.S.C. § 112), anticipation (35 U.S.C. § 102), and obviousness (35 U.S.C. § 103).
- After a trial, the jury found in favor of Evolved on all issues: the claims were not infringed and not invalid.
- Samsung filed a renewed motion for Judgment as a Matter of Law (JMOL) challenging the verdict on invalidity grounds.
- The Court's memorandum addresses whether Samsung met its burden to overturn the jury's verdict as a matter of law.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Written description ("dedicated preamble" limitation) | Sufficient disclosure in the '679 and '373 patents; expert (Laneman) showed support for the limitation. | Specification lacks disclosure for a dedicated preamble being sent; both experts opined lack of support. | For Evolved; Samsung did not meet clear/convincing burden. |
| Written description ("index of dedicated preamble") | Expert testified a POSITA would understand "information" in the specification covers an index. | No explicit disclosure of an index of a dedicated preamble; only discussion of indices in prior art, not specific to claim. | For Evolved; testimony supported jury's finding. |
| Anticipation (Wang prior art) | Wang does not disclose a dedicated preamble for a single mobile device nor the full claimed arrangement. | Wang discloses dedicated preamble as required; any distinctions are not meaningful. | For Evolved; sufficient record for jury's non-invalidity. |
| Obviousness (Kim + Nokia prior art) | Kim/Nokia do not disclose all elements, especially dedication of preambles to a particular device; ambiguous references. | Each claim element shown in Kim/Nokia; expert explained motivation to combine; Evolved’s expert’s criticisms unpersuasive. | For Evolved; jury could credit Evolved's expert over Samsung’s. |
