Calibrate Networks v. Shopify: Network Patent Suit Dismissed With Prejudice in 65 Days
Calibrate Networks LLC filed a patent infringement action against Shopify, Inc. in the Western District of Texas, asserting US9584633B2 covering methods and systems for managing network communications. The case ended just 65 days after filing when Calibrate voluntarily dismissed all claims with prejudice — before Shopify ever filed an answer.
A 65-Day Patent Assertion Against Shopify That Ended Before It Began
On April 23, 2025, Calibrate Networks LLC filed suit against Shopify, Inc. in the U.S. District Court for the Western District of Texas, asserting infringement of US9584633B2 — a patent covering a method and system for managing network communications. Shopify, a leading e-commerce platform provider, was the sole defendant. Calibrate was represented by Isaac Rabicoff of Rabicoff Law LLC, a firm frequently associated with non-practicing entity patent assertions.
On June 26, 2025 — just 65 days after filing — Calibrate filed a Notice of Voluntary Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Shopify had not yet served an answer or a motion for summary judgment, the notice was self-effectuating and required no court order. The court formally closed the case on June 27, 2025, ordering each party to bear its own costs, expenses, and attorney fees.
The speed of resolution — before any substantive response from Shopify — is consistent with early settlement or a decision by Calibrate to withdraw the assertion without extracting a licensing payment. The with-prejudice designation is significant: it permanently bars Calibrate from re-filing these specific claims against Shopify. Whether a private agreement underlies the dismissal is not disclosed in the public record, though the mutual cost-bearing order suggests no formal settlement payment was publicly acknowledged.
Filing to Voluntary dismissal in 65 days
65 days — resolved before defendant served an answer or summary judgment motion
Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): a self-effectuating dismissal
FRCP 41(a)(1)(A)(i) permits a plaintiff to voluntarily dismiss an action — without a court order — by filing a notice before the defendant serves an answer or a motion for summary judgment. Because Shopify had taken neither step, Calibrate’s notice automatically terminated the case. The court’s role was confirmatory only. The with-prejudice designation means this was not a simple procedural reset: Calibrate permanently surrendered its right to assert these specific claims against Shopify.
FRCP 41(a)(1)(A)(i)With prejudice means Calibrate cannot re-file against Shopify
A dismissal with prejudice operates as a final adjudication on the merits under res judicata principles. Calibrate Networks cannot re-assert US9584633B2 against Shopify in any subsequent action. This is a materially worse outcome for a patent assertion entity than a without-prejudice exit, which would preserve the right to refile. The public record does not disclose whether a private agreement — such as a licensing deal or covenant not to sue — accompanied the dismissal.
Claims permanently extinguishedShopify exits with permanent protection from this assertion
Shopify secured a with-prejudice dismissal before expending resources on an answer or dispositive motion. The cost-bearing order — each party covers its own fees — means Shopify recovers nothing in legal costs, but the permanent bar on re-assertion is a meaningful commercial win. Shopify’s network communications infrastructure faces no further exposure from Calibrate on this patent, absent any new patents or distinct claim theories. The outcome suggests Shopify’s litigation posture may have discouraged pursuit.
No re-assertion risk on US9584633B2Early exits signal pressure on NPE assertions against platform defendants
Cases resolved before the defendant files an answer — particularly with prejudice — typically signal either an early licensing agreement or a plaintiff decision that further pursuit is not viable. For e-commerce and network infrastructure defendants, this pattern suggests that well-resourced platform companies can deter assertions through early litigation posture alone. IP teams in the network communications space should monitor US9584633B2 for assertions against other defendants in the Western District of Texas.

Official order — verbatim text
The court’s order confirms that Calibrate’s Rule 41(a)(1)(A)(i) notice was self-effectuating — no judicial merits analysis was conducted and no claim construction occurred. The with-prejudice designation, chosen by Calibrate itself, converts what would otherwise be a neutral procedural exit into a permanent bar on re-assertion against Shopify. The mutual cost-bearing order forecloses any fee-shifting argument. Critically, the patent’s validity and the infringement allegations remain entirely unresolved on the merits, leaving US9584633B2 theoretically enforceable against other defendants.
US9584633B2 — Method and System for Managing Network Communications
US9584633B2 (application no. US14/211928) covers a method and system for managing network communications — a technical domain relevant to how platforms route, monitor, and control data flows across distributed network infrastructures. The patent’s claims likely address session management, traffic control, or communication protocol orchestration, though the precise scope requires a full prosecution history review. Patents in this category are frequently asserted against cloud-based and e-commerce platforms that operate large-scale communication layers.
For Shopify and comparable platform operators, network communications management patents represent a persistent assertion vector given the breadth of infrastructure required to support merchant and consumer interactions at scale. US9584633B2 has not been adjudicated on the merits in this action, meaning its enforceability against other defendants in the e-commerce and platform sector remains live. Companies building or deploying network session management, API gateway, or traffic routing systems should treat this patent as an active monitoring priority.
Should your team run an FTO against US9584633B2?
Any company operating network communication management infrastructure — including e-commerce platforms, cloud service providers, API gateway vendors, and network middleware developers — should evaluate exposure to US9584633B2. The patent’s dismissal with prejudice against Shopify does not limit its enforceability against other parties. If your product involves managing, routing, or monitoring network communications at the session or protocol level, an FTO analysis is warranted before scaling deployment.

What this case signals for the network communications IP landscape
A 65-day lifecycle and with-prejudice exit raises pointed questions about assertion strategy and defendant leverage in platform patent disputes.
With-prejudice exits are not cost-free for patent assertion entities
Calibrate permanently relinquished its claims against Shopify. For NPEs relying on the same patent across multiple defendants, a with-prejudice dismissal against one target can complicate broader licensing campaigns — defendants in parallel actions may cite it as a signal of weakness in the underlying assertion.
Western District of Texas remains active for network patent assertions
Despite Calibrate’s early exit, the W.D. Tex. continues to attract NPE filings in the network communications space. IP teams at platform and e-commerce companies should monitor US9584633B2 and related continuation filings for assertions against adjacent technology areas or different defendant classes.
Calibrate v Shopify — key questions answered
Calibrate Networks LLC filed a patent infringement suit against Shopify, Inc. in the Western District of Texas on April 23, 2025, asserting US9584633B2. The case was voluntarily dismissed with prejudice by Calibrate on June 26, 2025 — 65 days after filing — before Shopify filed any answer or dispositive motion. The court ordered each party to bear its own costs.
A with-prejudice dismissal permanently bars Calibrate Networks from re-filing the same patent infringement claims against Shopify under res judicata principles. Unlike a without-prejudice dismissal, Calibrate cannot refile this action in any court. The underlying patent US9584633B2 remains in force and may be asserted against other defendants.
US9584633B2 (application no. US14/211928) is a U.S. patent covering a method and system for managing network communications. The patent is relevant to platform operators, cloud infrastructure providers, and any entity managing network session or traffic routing at scale. Its merits were not adjudicated in this case.
The case resolved in 65 days before Shopify filed an answer, which is consistent with either an early private settlement or Calibrate’s decision that further litigation was not viable. The with-prejudice nature of the dismissal — chosen by Calibrate — suggests this was not a simple procedural hold. No public record discloses whether a licensing or settlement agreement was reached.
No. The with-prejudice dismissal only binds Calibrate Networks from re-asserting US9584633B2 against Shopify specifically. The patent’s validity and enforceability against other parties remains entirely unresolved. Companies in the network communications, e-commerce platform, or cloud infrastructure sectors should independently assess their exposure to this patent.
