211 F. Supp. 3d 858
E.D. Tex.2016Background
- Bench trial held March 29, 2016 in a patent infringement case between Genband and Metaswitch; Genband sought a permanent injunction and asserted damages, while Metaswitch raised laches and other equitable defenses; issues also included §101 patent eligibility; post-trial briefing followed bench findings; Genband acquired CVAS assets including several asserted patents prior to suit; jury found infringement and validity in January 2016 with about $8.17 million in damages; bench trial addressed equitable defenses and potential injunction, with rulings issued September 29, 2016.
- Genband sought a permanent injunction and argued irreparable harm and damages; Metaswitch asserted laches, implied waiver, equitable estoppel, and implied license; the court analyzed these defenses under Aukerman, SCA Hygiene, and related standards; court denied the permanent injunction and rejected the equitable defenses; court preserved issue of 101 eligibility for two patents but adjudicated the other defenses against Genband.
- Key factual points include Genband’s knowledge of Metaswitch (2001–2014), the CVAS acquisition context, Nortel’s bankruptcy reducing likelihood of delay impact, and CableLabs/IETF/ITU licensing structures impacting implied license and estoppel defenses.

Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Permanent injunction availability | Genband seeks injunction under equitable standard; irreparable harm and balance of hardships argued. | Metaswitch contends laches and other defenses bar injunction. | Denied the permanent injunction. |
| Laches as bar to damages | Delay insufficient to constitute prejudice; long window but rebutted by minimal infringing activity and CVAS timing. | Delay prejudices Metaswitch due to economic/evidentiary harm. | Laches not proven; damages recoverable. |
| Implied waiver | Nortel/CableLabs disclosures and policies implied waiver; knowledge of standard setting obligations. | No clear duty to disclose or breach by Nortel; no implied waiver. | Implied waiver not proven. |
| Equitable estoppel | Metaswitch relied on Nortel/Genband conduct creating security; would be prejudicial to Genband to enforce now. | No misrepresentation reliance; no knowledge of asserted patents during relevant periods. | Equitable estoppel not proven. |
| Implied license | CableLabs IPR and related licenses could imply license to asserted patents. | No grant of rights to those patents; licenses limited to specific NNCSI-owned rights. | Implied license not proven. |
