Pilot Energy vs Chevron & Scout: NGL Recovery Patent Settled in 721 Days
Pilot Energy Solutions and Pilot Intellectual Property filed suit against Chevron U.S.A. and Scout Energy Management in the Southern District of Texas, asserting US8505332B1 covering a natural gas liquid recovery process. The parties reached a settlement and filed a joint stipulation of dismissal with prejudice after nearly two years of litigation.
NGL recovery patent dispute between Pilot Energy and Chevron ends in settlement
On July 7, 2023, Pilot Energy Solutions, LLC and Pilot Intellectual Property, LLC (collectively ‘Pilot’) filed an infringement action against Chevron U.S.A., Inc. and Scout Energy Management, LLC in the U.S. District Court for the Southern District of Texas before Judge Alfred H. Bennett. The suit centered on US8505332B1, a patent covering a natural gas liquid (NGL) recovery process — a technology with direct commercial relevance to midstream and upstream oil and gas operations.
After 721 days of litigation, the parties filed a Notice of Settlement and Joint Stipulation of Dismissal with Prejudice on June 27, 2025. Judge Bennett ordered all claims dismissed with prejudice pursuant to Rule 41(a)(1)(A)(ii). The with-prejudice designation means Pilot is permanently barred from reasserting these specific claims against Chevron and Scout on the same patent, reflecting a negotiated resolution rather than a judicial merits ruling.
The nearly two-year duration is consistent with cases that proceed through at least claim construction or substantive discovery before settling. The mutual cost-bearing arrangement — no fee-shifting to either side — is a common feature of negotiated settlements and suggests neither party achieved a clear leverage advantage. The precise financial terms, any licensing arrangement, or operational commitments remain confidential and are not disclosed in the public record.

Dismissed with prejudice: what the settlement resolution means for both parties
Dismissal with prejudice under Rule 41 bars future refiling
A dismissal with prejudice under Rule 41(a)(1)(A)(ii) is a final adjudication on the merits for res judicata purposes. Pilot cannot refile the same infringement claims against Chevron or Scout on US8505332B1. This is the standard mechanism used to close patent cases following a negotiated settlement — the court retains no ongoing jurisdiction unless the parties separately preserve enforcement rights.
Permanent bar on refilingPilot’s patent survives — enforceability intact against third parties
A dismissal with prejudice following settlement does not invalidate US8505332B1. The patent remains in force and can be asserted against other parties in the NGL recovery space. Pilot’s decision to settle rather than litigate to judgment preserves the patent’s claim scope — no adverse claim construction or invalidity ruling was entered on the public record that competitors could later cite.
Patent remains enforceableChevron and Scout resolve exposure — terms remain confidential
Chevron and Scout secured a with-prejudice dismissal, eliminating litigation risk on these specific claims. Whether the resolution involved a license, royalty arrangement, or process modification is not disclosed. The cost-neutral order — each party bearing its own fees — is consistent with a commercially negotiated exit rather than a capitulation. Scout’s separate involvement suggests the asserted process may have been deployed across multiple operator relationships.
Risk resolved, terms privateNGL recovery IP remains active — watch for further assertions
With US8505332B1 intact and no invalidation on record, other operators using similar NGL recovery processes remain potentially exposed. Pilot’s IP holding structure — a dedicated IP entity alongside an operating entity — is consistent with a licensing-forward strategy. Companies in midstream processing, produced gas handling, and field-level NGL extraction should evaluate FTO exposure against this patent, particularly given the confidential settlement terms with a major operator like Chevron.

Official order — verbatim text
The joint stipulation of dismissal with prejudice, ordered by Judge Bennett under Rule 41(a)(1)(A)(ii), reflects a mutual agreement to terminate all claims permanently. The with-prejudice designation is legally significant: it carries res judicata effect, meaning Pilot is foreclosed from reasserting these claims against Chevron and Scout on the same patent. The court made no findings on infringement, validity, or claim scope — the public record is silent on merits. The cost-neutral order, with each party bearing its own fees and expenses, is consistent with a balanced negotiated settlement rather than a one-sided resolution.
US8505332B1 — Natural Gas Liquid Recovery Process
US8505332B1, filed under application number US12/122336, protects a natural gas liquid (NGL) recovery process. NGL recovery encompasses the separation and capture of heavier hydrocarbon components — ethane, propane, butane, and natural gasoline — from a raw gas stream, a critical step in both upstream production and midstream processing. The patent’s B1 designation indicates it issued without post-grant amendment, suggesting the original claims were granted as filed.
In the context of U.S. oil and gas production, NGL recovery processes are commercially significant — NGL yields contribute materially to field economics, particularly in liquids-rich plays. A patent covering a process method in this space can reach broadly across operators, service companies, and asset managers. Pilot’s assertion against both a major integrated company (Chevron) and an independent asset manager (Scout) suggests the claimed process is not limited to a single operational scale, raising the relevance of this patent for the wider upstream and midstream sector.
Should your team run an FTO against US8505332B1?
Any company involved in natural gas liquid recovery — whether operating gas processing facilities, managing upstream assets with associated gas streams, or deploying separation technologies in the field — should assess freedom-to-operate exposure against US8505332B1. The Pilot v. Chevron settlement confirms this patent has been actively enforced against a major operator. The confidential resolution means there is no public claim construction to narrow the scope, leaving the patent’s full claim breadth in play for future targets.

What this case signals for the oil and gas NGL processing IP landscape
A settlement against Chevron validates Pilot’s patent posture and leaves US8505332B1 as an active threat for other NGL recovery operators.
Dismissal with prejudice confirms settlement — patent claim scope is preserved
No adverse ruling on validity or infringement was issued. US8505332B1 carries no litigation-weakened claim construction into future disputes. Any operator relying on a prior-art or non-infringement argument must build that case independently — they cannot leverage this resolution.
Pilot’s dual-entity structure signals a structured IP licensing strategy
The separation of Pilot Energy Solutions (operating) and Pilot Intellectual Property (holding) is a common architecture for entities pursuing patent monetisation. This structure typically signals intent to assert the patent broadly across an industry rather than defend a single product line.
Pilot v Chevron — key questions answered
The case was dismissed with prejudice on June 27, 2025, following a joint settlement between all parties. Judge Alfred H. Bennett ordered all claims dismissed under Rule 41(a)(1)(A)(ii), with each party bearing its own attorney fees, expenses, and costs. No merits ruling on infringement or validity was issued.
Pilot Energy Solutions and Pilot Intellectual Property asserted US8505332B1, which covers a natural gas liquid recovery process. The patent was filed under application number US12/122336 and issued as a B1 patent, indicating no post-grant amendment to the claims.
No. A dismissal with prejudice following settlement carries no findings on patent validity or infringement. US8505332B1 remains in force and enforceable against third parties. Pilot is barred from reasserting these specific claims against Chevron and Scout, but the patent’s legal status is unaffected for all other potential defendants.
Scout Energy Management, an independent oil and gas asset manager, was named as a co-defendant, suggesting the asserted NGL recovery process may have been deployed on assets managed by Scout, potentially on behalf of other parties. The public record does not disclose the specific operational basis for Scout’s inclusion.
The court ordered that each party bear its own attorney fees, expenses, and costs. This is a standard arrangement in negotiated patent settlements and does not imply that either side prevailed on the merits. It contrasts with an exceptional case fee award under 35 U.S.C. § 285, which was not triggered here.
