Aculon v. Electrolab & E9 Treatments: 7-Patent SAM Coating Dispute Settled With Prejudice
Aculon, Inc. asserted seven patents covering self-assembled monolayer (SAM and SAMP) surface treatment methods for crude oil service equipment against Electrolab, Inc. and E9 Treatments, Inc. in the Western District of Texas. The case resolved via a confidential settlement after 538 days, with all claims and counterclaims dismissed with prejudice and each party bearing its own legal costs.
Seven SAM/SAMP Patents, Two Defendants, One Settlement: Aculon v. Electrolab
On June 2, 2023, Aculon, Inc. filed suit in the Western District of Texas (Case No. 5:23-cv-00720) before Judge Xavier Rodriguez, asserting infringement of seven US patents covering self-assembled monolayer (SAM) and self-assembled monolayer polymer (SAMP) surface treatment technologies. The asserted patents span bonded-layer treatment methods, mono-, di- and tri-headed SAM application methods, and SAMP-coated components specifically engineered for crude oil service operations, including level sensors and cooperating surfaces.
The case closed on November 21, 2024 — 538 days after filing — through a stipulated dismissal with prejudice filed pursuant to Rule 41 of the Federal Rules of Civil Procedure. The dismissal was expressly linked to a settlement agreement between Aculon, Electrolab, and E9 Treatments. A with-prejudice dismissal means Aculon cannot refile the same claims against these defendants on these patents; the defendants’ counterclaims were likewise extinguished with prejudice. Each party agreed to bear its own attorneys’ fees, costs, and expenses.
A 538-day litigation timeline ending in settlement before trial is consistent with cases that reach substantive motion practice or claim construction before the parties reach commercial terms. The with-prejudice structure and mutual cost-bearing suggest a negotiated resolution rather than a one-sided capitulation, though the financial terms, any licence grant, and the trigger for settlement remain confidential and cannot be determined from the public record. The inclusion of two defendants — Electrolab as an accused manufacturer or service provider and E9 Treatments as a counterclaim plaintiff — suggests the dispute involved overlapping commercial interests in oil-field surface treatment technology.
Filing to Dismissed with Prejudice in 538 days
538 days from filing to dismissal — consistent with cases resolving pre-trial following substantive discovery
Settled with prejudice: what the Rule 41 dismissal means for both parties
Rule 41 dismissal with prejudice following settlement
Under Rule 41(a)(1)(A)(ii) of the Federal Rules of Civil Procedure, parties may jointly stipulate to dismiss an action. When that dismissal is ‘with prejudice,’ the claims are resolved on a final basis — Aculon cannot refile the same infringement claims against Electrolab or E9 Treatments on these seven patents. The linkage to a settlement agreement suggests the parties negotiated resolution terms before executing the stipulation, making this a consensual, permanent close of the litigation.
Permanent bar on refilingAculon’s patents survive, but claims are extinguished against these defendants
A with-prejudice settlement dismissal does not invalidate Aculon’s seven SAM/SAMP patents — they remain enforceable against third parties. However, Aculon surrenders the right to re-assert these specific claims against Electrolab and E9 Treatments absent new infringing acts post-settlement. Any licence, royalty, or covenant-not-to-sue embedded in the settlement agreement would further shape Aculon’s enforcement posture, but those terms are not public.
Patents remain enforceable vs. third partiesCounterclaims dismissed; litigation risk resolved for Electrolab and E9 Treatments
E9 Treatments had filed counterclaims, which are also dismissed with prejudice under the stipulation. Both defendants exit the litigation without a court-adjudicated finding of infringement or validity — a commercially significant outcome that avoids an adverse judgment on the public record. The mutual cost-bearing arrangement suggests neither party achieved a clearly dominant negotiating position, though the specific commercial terms of the settlement are confidential.
No infringement finding on recordSAM/SAMP coating IP remains a live enforcement risk in oil-field services
Aculon’s portfolio of seven SAM and SAMP patents covering crude oil service equipment treatment methods remains intact and enforceable. Companies operating in oil-field surface treatment, corrosion mitigation, or downhole equipment coating should note that this settlement does not resolve the underlying validity or scope questions — it simply closes this dispute. Future targets of Aculon enforcement cannot rely on this case as dispositive prior art or invalidity precedent.

Official order — verbatim text
The stipulated dismissal language is comprehensive: it explicitly covers ‘all claims, counterclaims, defenses, and demands,’ ensuring no residual procedural posture survives the settlement. The with-prejudice designation is bilateral — Aculon’s infringement claims and E9 Treatments’ counterclaims are equally extinguished. Critically, the verdict contains no merits findings on infringement, validity, or claim scope, meaning the seven asserted SAM/SAMP patents emerge from this litigation with their enforceability and claim breadth legally undisturbed. The mutual cost-bearing clause is commercially neutral and consistent with a negotiated resolution where both sides assessed continued litigation as economically irrational.
US9476754B2 — SAM/SAMP Surface Treatment Methods for Crude Oil Equipment
The seven asserted patents — anchored by US9476754B2 (App. No. 14/099497) and extending through US10822559B2, US10059892B2, US10150924B2, US10934497B2, US10844299B2, and US9688926B2 — form a tightly clustered family covering self-assembled monolayer (SAM) and self-assembled monolayer polymer (SAMP) surface treatment technologies. The patents protect methods of applying mono-, di-, and tri-headed SAM architectures to industrial equipment, as well as SAMP-coated components including level sensors and cooperating surfaces specifically engineered for crude oil service environments where corrosion and fouling resistance are operationally critical.
From a competitive standpoint, Aculon’s SAM/SAMP portfolio addresses a high-value problem in upstream and midstream oil and gas operations — surface degradation of downhole and surface equipment exposed to corrosive crude oil media. The breadth of the asserted family, spanning application methods, kit formulations, and specific coated-component configurations, creates layered enforcement risk for any company offering surface treatment services or coated equipment for crude oil applications. The fact that Aculon pursued two defendants simultaneously — and obtained a with-prejudice settlement — suggests the portfolio is commercially robust enough to compel resolution without merits adjudication.
Should you run an FTO against Aculon’s SAM/SAMP crude oil coating patents?
Any company developing, supplying, or applying self-assembled monolayer or polymer surface treatments to equipment used in crude oil service operations — including level sensors, valves, pipes, or cooperating mechanical surfaces — should treat Aculon’s seven-patent family as a live clearance risk. The with-prejudice settlement in this case confirms the portfolio is actively enforced, and no court ruling has narrowed the claims or found any of the seven patents invalid. Product teams commercialising anti-corrosion or anti-fouling surface treatment kits, methods, or coated hardware for oilfield deployment are particularly exposed.
PatSnap Eureka’s FTO Search Agent can map your specific surface treatment process or product configuration against all seven asserted Aculon patents — US9476754B2, US10822559B2, US10059892B2, US10150924B2, US10934497B2, US10844299B2, and US9688926B2 — and surface related continuation applications, divisionals, and family members that may extend coverage. Eureka’s claim-level analysis identifies which steps in a SAM or SAMP application method fall within independent claim scope, enabling your IP and R&D teams to design around risk before product launch.

What this case signals for the oilfield surface coating IP landscape
A seven-patent assertion settled with prejudice — Aculon’s SAM/SAMP portfolio is commercially potent and actively enforced.
Multi-patent assertions raise settlement pressure before trial
Asserting seven patents across a connected technology family — as Aculon did here — dramatically increases discovery burden and claim construction complexity for defendants. This litigation structure typically accelerates settlement timelines because defendants face compounding cost exposure. Companies commercialising surface treatment technology in oil and gas should audit exposure across entire SAM/SAMP patent families, not just individual patents.
With-prejudice settlement protects defendants without creating invalidity precedent
Electrolab and E9 Treatments resolved their exposure without a court ruling on validity or infringement. While commercially rational, this means Aculon’s patent claims remain untested on the merits — no prosecution history estoppel, no claims narrowing, no invalidity finding. Third-party competitors in crude oil equipment treatment cannot point to this case as weakening Aculon’s enforcement rights.
Aculon v Electrolab — key questions answered
Aculon, Inc. filed a patent infringement action in the Western District of Texas on June 2, 2023 asserting seven SAM and SAMP surface coating patents against Electrolab, Inc. and E9 Treatments, Inc. The case closed on November 21, 2024 — 538 days later — through a stipulated dismissal with prejudice pursuant to a settlement agreement, with each party bearing its own costs.
Aculon asserted seven US patents: US9476754B2, US10822559B2, US10059892B2, US10150924B2, US10934497B2, US10844299B2, and US9688926B2. The patents cover self-assembled monolayer (SAM) and self-assembled monolayer polymer (SAMP) surface treatment methods and coated components specifically for crude oil service equipment, including level sensors, cooperating surfaces, and application kits.
A dismissal with prejudice bars Aculon from refiling the same infringement claims against Electrolab and E9 Treatments on these seven patents. However, the patents themselves remain valid and enforceable — no court ruled on their validity or scope. Aculon retains full enforcement rights against other parties in the crude oil service equipment and surface treatment sector.
The public record does not disclose the financial or commercial terms of the settlement. The stipulated dismissal only confirms that the parties reached an agreement, that all claims and counterclaims are dismissed with prejudice, and that each party bears its own attorneys’ fees and costs. Any licence grant, royalty, or covenant-not-to-sue would be contained in the confidential settlement agreement.
The settlement does not resolve or narrow Aculon’s patent claims — it simply closes this particular dispute. Companies commercialising SAM or SAMP surface treatment methods, application kits, or coated equipment for crude oil service operations remain exposed to enforcement risk from all seven asserted patents plus any continuation or divisional applications in Aculon’s prosecution pipeline. A formal FTO analysis against each patent’s independent claims is advisable before product launch or commercial scale-up.
