Woodbury Wireless v. Verizon: 7-Patent MIMO Suit Ends in Dismissal With Prejudice
Woodbury Wireless, LLC filed a seven-patent infringement action against Verizon Communications and Cellco Partnership (dba Verizon Wireless) in the Eastern District of Texas, asserting MIMO wireless transmission patents. All claims were dismissed with prejudice after 417 days, with each party bearing its own costs — a resolution that forecloses any future refiling of these specific claims.
Seven MIMO patents, one stipulated end: anatomy of Woodbury v. Verizon
On December 20, 2022, Woodbury Wireless, LLC filed suit in the Eastern District of Texas before Judge Rodney Gilstrap, asserting seven U.S. patents — US9503163B2, US9859963B2, US10211895B2, US11108443B2, US9496930B2, US10516451B2, and US9584197B2 — all directed at MIMO (multiple-input multiple-output) wireless methods and systems, including overlapping MIMO physical sector techniques. The defendants were Verizon Communications, Inc. and its operating subsidiary Cellco Partnership, doing business as Verizon Wireless.
The case closed on February 10, 2024, via a joint stipulation of dismissal filed at Dkt. No. 44. Judge Gilstrap accepted the stipulation and ordered all of Plaintiff’s claims dismissed with prejudice, meaning Woodbury Wireless cannot refile these same claims against these defendants. Notably, the order specified that each party bears its own costs, attorneys’ fees, and expenses — suggesting the parties reached a private resolution without a formal damages award or publicly disclosed settlement sum.
The 417-day duration and the mutual cost-bearing order are consistent with a negotiated resolution reached prior to trial, though the public record does not confirm whether a confidential licensing arrangement accompanied the stipulation. The relatively swift conclusion — for a seven-patent EDTX matter — may reflect pressure from Verizon’s IPR or invalidity challenges, or a commercial agreement that rendered continued litigation unnecessary. The precise terms driving dismissal remain undisclosed.

Dismissed with prejudice: what the stipulated order means for both parties
Stipulated dismissal with prejudice ends all claims permanently
A dismissal with prejudice, entered via joint stipulation, operates as a final adjudication on the merits. Woodbury Wireless is permanently barred from re-asserting these seven MIMO patents against Verizon in any future action involving the same claims. Unlike a dismissal without prejudice, there is no opportunity to refile — the litigation chapter on these patents versus this defendant is conclusively closed.
No re-filing permittedWoodbury Wireless forfeits future litigation rights against Verizon
By agreeing to dismissal with prejudice, Woodbury Wireless surrendered any right to sue Verizon again on these seven patents. Whether this reflects a negotiated licensing payment (undisclosed in the public record), a strategic retreat in the face of invalidity risk, or an agreed cross-license cannot be determined from the docket alone. The mutual cost-bearing order suggests neither party conceded liability.
Claims extinguishedVerizon secures permanent bar on these MIMO claims
Verizon and Cellco Partnership obtained a dismissal with prejudice — the strongest available litigation shield short of an invalidity ruling. These seven MIMO patents cannot be weaponised against Verizon again in any future lawsuit on the same claims. The own-costs order means Verizon avoided any fee-shifting exposure, which is significant given the breadth of the patent portfolio asserted.
Permanent protection securedMIMO IP remains live against other wireless carriers
The dismissal with prejudice binds only Woodbury Wireless and Verizon. The seven MIMO patents — covering overlapping MIMO physical sector methods and related wireless transmission systems — remain potentially enforceable against other carriers and equipment vendors. Companies deploying MIMO technologies in 4G/5G networks should treat this case as a signal that this portfolio is actively monetised, even if Verizon specifically is no longer a target.

Official order — verbatim text
The Court’s order accepts the parties’ joint stipulation verbatim and imposes a with-prejudice bar on all of Plaintiff’s claims — the strongest available finality short of a merits judgment. The own-costs provision is notable: fee-shifting under 35 U.S.C. § 285 was not triggered, suggesting neither party sought an ‘exceptional case’ finding. The absence of any damages recital or injunction is consistent with a confidential resolution, though the public record does not confirm this.
US9503163B2 — MIMO wireless transmission methods and overlapping sector systems
The seven patents asserted in this case — led by US9503163B2 (application filed 2014) and extending to US11108443B2 (application filed 2019) — form a cohesive portfolio directed at multiple-input multiple-output (MIMO) wireless methods and systems, including overlapping MIMO physical sector techniques. MIMO is foundational to 4G LTE and 5G NR performance, enabling higher spectral efficiency through simultaneous multi-stream transmission. The application window spanning 2014–2019 places these patents squarely within the commercial rollout of advanced LTE and early 5G infrastructure.
For major wireless carriers, MIMO method patents present distinctive enforcement risk because the technology is embedded in network infrastructure rather than consumer devices — making design-arounds operationally complex and costly. Woodbury Wireless’s portfolio, covering both methods and apparatus claims across seven grants, creates layered liability exposure. The commercial relevance of overlapping physical sector configurations is heightened in dense urban 5G deployments, where advanced MIMO beamforming is standard practice. Other carriers not party to this dismissal should treat the portfolio as an active enforcement risk.
Should you run an FTO against US9503163B2 and the Woodbury MIMO portfolio?
Any organisation designing, deploying, or operating MIMO wireless systems — including network carriers, base station vendors, chipset manufacturers, and infrastructure OEMs — should assess freedom-to-operate against the Woodbury Wireless portfolio. The seven patents cover MIMO methods and overlapping physical sector configurations that are directly implicated in 4G/5G network deployments. The with-prejudice dismissal protects only Verizon; all other market participants remain exposed.

What Woodbury v. Verizon signals for MIMO wireless IP enforcement
A seven-patent MIMO suit resolved in 417 days with a prejudicial dismissal carries clear signals for wireless carriers and IP counsel.
EDTX remains the venue of choice for MIMO patent assertions
Woodbury Wireless selected Judge Gilstrap’s court in the Eastern District of Texas — consistently among the most plaintiff-friendly venues for patent infringement. Wireless carriers and component suppliers with MIMO exposure should monitor EDTX dockets proactively, as this court’s procedural pace can create settlement pressure before claim construction.
Seven-patent portfolios signal licensing strategy, not trial strategy
Filing with seven related MIMO patents rather than a single flagship claim typically reflects a licensing-oriented enforcement model. The breadth of the assertion makes invalidity challenges costly for defendants and creates negotiating leverage. Companies in the MIMO wireless space should assess their own FTO posture across patent families, not just individual granted claims.
Woodbury v Verizon — key questions answered
All claims were dismissed with prejudice via joint stipulation on February 10, 2024. Judge Gilstrap’s order bars Woodbury Wireless from refiling these claims against Verizon. Each party was ordered to bear its own costs, attorneys’ fees, and expenses. No damages award or public settlement sum appears in the docket.
Woodbury Wireless asserted seven U.S. patents: US9503163B2, US9859963B2, US10211895B2, US11108443B2, US9496930B2, US10516451B2, and US9584197B2. All are directed at MIMO wireless methods and systems, including overlapping MIMO physical sector techniques, with application dates ranging from 2014 to 2019.
No. The dismissal with prejudice binds only the named parties — Verizon Communications and Cellco Partnership dba Verizon Wireless. The seven MIMO patents remain in force and are potentially enforceable against other carriers, equipment manufacturers, and infrastructure vendors operating MIMO wireless networks.
The court ordered each party to bear its own attorneys’ fees and expenses, meaning no fee-shifting occurred under 35 U.S.C. § 285. This suggests neither party sought nor obtained an ‘exceptional case’ finding. It is consistent with a negotiated resolution, though it does not preclude a confidential licensing payment being made outside the court’s formal order.
