CommWorks Solutions v. Open Text — Fax-to-Email Patents Dismissed Without Prejudice
CommWorks Solutions, LLC filed suit against Open Text, Inc. in the Eastern District of Texas, asserting two patents covering facsimile-to-email technology against OpenText’s RightFax system. After 217 days, CommWorks voluntarily dismissed all claims without prejudice under Rule 41(a)(1)(A)(i), leaving the door open for future litigation.
A tactical retreat or a quiet settlement? CommWorks walks away without prejudice
CommWorks Solutions, LLC filed Case No. 2:23-cv-00533 in the Eastern District of Texas on November 20, 2023, before Judge Rodney Gilstrap — one of the most patent-active judges in the country. The plaintiff asserted two patents, US8533278B2 and US8224909B2, both directed to facsimile-to-email technology, against Open Text, Inc.’s RightFax system, a widely deployed enterprise document delivery platform.
On June 24, 2024 — 217 days after filing — CommWorks filed a Notice of Voluntary Dismissal under Rule 41(a)(1)(A)(i), dismissing all claims without prejudice. The court accepted and acknowledged the dismissal, ordered that each party bear its own costs, attorneys’ fees, and expenses, and directed the clerk to close the case. No adjudication on the merits occurred.
The absence of a fee-shifting order and the use of Rule 41(a)(1)(A)(i) — which requires no court approval and is available only before the defendant serves an answer or motion for summary judgment — suggests the dismissal came relatively early in the litigation lifecycle. Whether the parties reached a private resolution or CommWorks elected to preserve optionality for a future filing is not discernible from the public record. The without-prejudice designation is commercially significant: the same patents may be asserted again.

Voluntary dismissal without prejudice: what the order means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to exit
Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order before the defendant serves an answer or a motion for summary judgment. The court here accepted and acknowledged the dismissal — standard practice, as no judicial approval is required. This mechanism signals the case was resolved or abandoned at an early procedural stage, before significant merits briefing.
No merits adjudicationWithout prejudice: CommWorks can refile against OpenText
A dismissal without prejudice does not extinguish the underlying claims. CommWorks retains the right to assert US8533278B2 and US8224909B2 against OpenText or other defendants in a future action, subject to applicable statutes of limitations and any tolling considerations. The public record does not disclose whether a private settlement agreement — which could include licensing terms or a covenant not to sue — underpins this dismissal.
Future refiling possibleOpenText exits without an invalidity ruling or license on record
Open Text, Inc. obtained no declaratory judgment of invalidity or non-infringement, and no finding of patent exhaustion. The each-party-bears-own-costs order suggests neither side extracted a concession that would appear in a public ruling. OpenText’s RightFax product remains potentially exposed to a refiling unless a private covenant or license was secured as part of any undisclosed resolution.
No invalidity findingFax-to-email IP remains live — RightFax competitors should take note
With no claims adjudicated, US8533278B2 and US8224909B2 remain fully enforceable. Other vendors in the enterprise fax-to-email and document delivery space — whose products share architectural similarities with RightFax — face the same exposure that initially attracted this assertion. The without-prejudice outcome typically signals that the patent holder views its IP as commercially viable for continued enforcement or licensing activity.

Official order — verbatim text
The court’s order accepts and acknowledges the Rule 41(a)(1)(A)(i) voluntary dismissal without prejudice, confirming that all claims and causes of action are extinguished without a merits ruling. The each-party-bears-own-costs directive is notable: it forecloses any fee award under 35 U.S.C. § 285, meaning neither party successfully argued exceptional-case status. The phrasing ‘accepts and acknowledges’ is procedurally standard and does not constitute any judicial assessment of the underlying infringement allegations or patent validity.
US8533278B2 & US8224909B2 — Facsimile-to-Email Communication Technology
US8533278B2 (application No. 13/490403) and US8224909B2 (application No. 12/369785) both address the technical domain of facsimile-to-email (FEM) communications — systems and methods that receive inbound fax transmissions and deliver them as email messages to end users. This technology underpins enterprise document delivery platforms that bridge legacy PSTN fax infrastructure with modern email and cloud storage environments.
The assertion of these two patents against OpenText’s RightFax system — one of the most widely deployed enterprise fax platforms globally — suggests CommWorks believes the patents cover core architectural elements of fax-to-email workflows rather than peripheral features. Any vendor offering on-premises or cloud-based fax-to-email conversion, including unified communications platforms and managed fax services, should treat these patent numbers as active enforcement risks until either invalidated or licensed.
Should your product team run an FTO against US8533278B2 and US8224909B2?
If your product routes inbound fax transmissions to email inboxes — whether as a standalone fax server, a cloud fax service, or a unified communications module — these two patents represent a live clearance risk. CommWorks dismissed its OpenText case without prejudice, meaning neither patent has been adjudicated or narrowed. Any product team preparing to launch or scale a fax-to-email feature should conduct a freedom-to-operate analysis against both patent families before go-to-market.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map product functionality against the claim sets of US8533278B2 and US8224909B2, identify prior art that could support an invalidity argument, and surface any continuation or related patents in the CommWorks portfolio that may extend the enforcement risk. Run a targeted FTO search now to assess exposure before a refiling occurs.

Portfolio viewWhat this case signals for the enterprise fax-to-email IP landscape
A without-prejudice exit in E.D. Texas rarely signals the end of an enforcement campaign — it often signals a pivot.
E.D. Texas remains the venue of choice for asserting communication patents
Judge Gilstrap’s docket is among the highest-volume patent dockets in the country. The choice of this venue for fax-to-email patents signals a plaintiff serious about litigation leverage. Companies with legacy or cloud-based document delivery products should monitor filings here closely for follow-on actions by CommWorks.
Without-prejudice dismissal keeps enforcement pressure on the whole sector
Because no claim was invalidated and no non-infringement finding was entered, every competitor in the enterprise fax-to-email space remains exposed to the same two patents. A dismissed-without-prejudice case combined with an each-party-bears-costs order may indicate a licensing discussion occurred — but the terms, if any, are private.
CommWorks’ portfolio history suggests a structured licensing strategy
Patent assertion entities that file in E.D. Texas under Rule 41(a)(1)(A)(i) and exit without a fee award frequently operate on a licensing-first model. Monitoring CommWorks’ future filings across district courts could reveal the scope of its assertion campaign across the enterprise communications sector.
US8533278B2 claim scope warrants urgent FTO review for RightFax-adjacent products
The two asserted patents cover core facsimile-to-email conversion workflows. Any product that routes inbound fax transmissions to email inboxes — whether on-premises or cloud-hosted — should be assessed against these claim sets before CommWorks initiates a follow-on filing with a refined infringement theory.
CommWorks v Open — key questions answered
CommWorks Solutions, LLC asserted two patents: US8533278B2 (application 13/490403) and US8224909B2 (application 12/369785). Both patents relate to facsimile-to-email (FEM) communication technology. The complaint targeted OpenText’s RightFax system, a widely used enterprise document delivery platform.
CommWorks filed a voluntary dismissal under Rule 41(a)(1)(A)(i), which allows a plaintiff to dismiss without court approval before the defendant answers or moves for summary judgment. The court accepted the dismissal without prejudice. The public record does not disclose whether a private settlement or licensing agreement drove the decision.
Yes. A dismissal without prejudice does not bar refiling. CommWorks retains the right to assert US8533278B2 and US8224909B2 against OpenText or other defendants in a future action, subject to applicable statutes of limitations. Whether any private covenant not to sue was negotiated is not reflected in the public court record.
CommWorks Solutions was represented by Kheyfits Belenky LLP and The Stafford Davis Firm (Tyler), with attorneys including Andrey Belenky and Dmitry Kheyfits. Open Text was represented by Orrick, Herrington & Sutcliffe LLP and Venable LLP (Washington DC), with attorneys including Timothy J. Carroll and Laura Ann Wytsma.
The court ordered that each party bear its own costs, attorneys’ fees, and expenses. No fee-shifting award was made under 35 U.S.C. § 285. This mutual cost-bearing arrangement is standard in voluntary dismissals under Rule 41(a)(1)(A)(i) and does not constitute a finding that the case was exceptional under the Patent Act.
