LiquidPower v. Baker Hughes: Federal Circuit Affirms Patent Unpatentable
LiquidPower Specialty Products asserted US8022118B2 — covering drag reduction of asphaltenic crude oils — against Baker Hughes, a GE Company and Baker Hughes Holdings. The Federal Circuit affirmed the unpatentability finding, closing the appeal after 1,001 days. The ruling leaves LiquidPower without patent protection in this technology domain.
Federal Circuit closes the door on LiquidPower's crude oil drag-reduction patent
LiquidPower Specialty Products, Inc. appealed to the United States Court of Appeals for the Federal Circuit (Case No. 20-2001) challenging a finding that US8022118B2 — its patent covering drag reduction of asphaltenic crude oils — was unpatentable. The defendants, Baker Hughes, a GE Company, LLC and Baker Hughes Holdings, LLC, successfully defended the invalidity/cancellation action below, prompting LiquidPower's appeal, filed on 16 July 2020.
The Federal Circuit considered the appeal on a patentability/invalidity basis and issued a terse but definitive disposition: 'AFFIRMED.' The recorded Basis of Termination is 'Unpatentable,' confirming that the appellate court found no reversible error in the underlying finding that US8022118B2 does not meet the statutory requirements for patentability. The case was closed on 13 April 2023.
The 1,001-day appellate duration — nearly three years — suggests substantive briefing and deliberation, though the terseness of the published verdict text limits visibility into the court's specific reasoning. The specific grounds of unpatentability and any claim-by-claim analysis are not detailed in the available record. LiquidPower's options beyond this Federal Circuit ruling are not disclosed in the public record.

US8022118B2 — Drag Reduction of Asphaltenic Crude Oils
R&D and product teams developing drag reduction agents or flow assurance treatments for asphaltenic crude oil pipelines should note that US8022118B2 has been confirmed unpatentable and is no longer an active blocking right. However, LiquidPower Specialty Products may hold additional patents in drag-reduction chemistry, and Baker Hughes holds its own IP in this sector. Before commercialising DRA technology for asphaltenic crudes, a systematic FTO review across related patent families remains the prudent course.
Official order — verbatim text
The Federal Circuit's published disposition — 'THIS CAUSE having been considered, it is ORDERED AND ADJUDGED: AFFIRMED' — is a summary affirmance, confirming the tribunal's finding that US8022118B2 is unpatentable. The brevity of the order is consistent with summary affirmance practice at the Federal Circuit, and the recorded Basis of Termination is 'Unpatentable.' The specific invalidity grounds and claim-level analysis are not detailed in the available record.
Federal Circuit affirms: what the ruling means for both parties
What 'AFFIRMED' means at the Federal Circuit level
An affirmance by the Federal Circuit means the appellate panel reviewed the record and found no reversible error in the decision below. The lower tribunal's finding that US8022118B2 is unpatentable is now upheld by the nation's primary patent appellate court. The patent's invalidity stands as a matter of law, and the Federal Circuit's affirmance is binding precedent within its jurisdiction.
No reversible error foundLiquidPower loses enforceable rights in drag-reduction technology
The affirmance confirms that US8022118B2 is unpatentable, stripping LiquidPower Specialty Products of the exclusive rights it sought to enforce against Baker Hughes. With the Federal Circuit having affirmed, the patent cannot be enforced in its current form. LiquidPower's remaining options — such as a petition for certiorari to the Supreme Court — are not disclosed in the available record.
Patent unenforceableBaker Hughes secures freedom from the asserted patent
Baker Hughes, a GE Company and Baker Hughes Holdings successfully defended the invalidity finding at both the tribunal level and on appeal. The Federal Circuit affirmance means Baker Hughes is no longer exposed to infringement liability under US8022118B2. The ruling clears the patent from Baker Hughes's freedom-to-operate exposure in drag reduction of asphaltenic crude oils, at least with respect to this specific patent.
Cleared of infringement riskDrag-reduction technology space opens with key patent invalidated
The affirmance of unpatentability removes US8022118B2 as an IP barrier in the asphaltenic crude oil drag-reduction market. Competitors and R&D teams working in pipeline flow assurance and crude oil transportation should note that this patent is no longer a blocking right. However, LiquidPower or others may hold related patents in this domain not addressed by this case; a full FTO analysis remains advisable.

R&D signals in the drag-reduction and pipeline chemistry space
Forward-looking patent intelligence derived from the LiquidPower v. Baker Hughes Federal Circuit ruling — covering portfolio activity, technology trends, and white space in oilfield drag-reduction chemistry.
LiquidPower's surviving IP in drag-reduction chemistry
With US8022118B2 confirmed unpatentable, the strategic question is what LiquidPower Specialty Products still holds in drag-reduction formulations. Mapping LiquidPower's remaining active patents — particularly in DRA polymer compositions and asphaltene-compatible chemistries — can reveal whether the company retains enforceable positions in adjacent pipeline treatment technology.
LiquidPower portfolioFiling trends in asphaltenic crude oil drag reduction
Asphaltenic crude drag reduction is an active R&D area driven by growing production of heavy crudes. Tracking patent filing trends in DRA polymer compositions, asphaltene inhibition, and pipeline flow assurance reveals where innovation is concentrated and which assignees are building blocking positions as US8022118B2 exits the landscape.
DRA filing trendsBaker Hughes's patent position in pipeline flow assurance
Baker Hughes, a GE Company and Baker Hughes Holdings are significant patent filers in oilfield services and pipeline chemistry. Analysing their active patent portfolio in drag reduction, flow assurance, and crude oil treatment can indicate whether the company is building IP to protect the technology space it successfully cleared through this litigation.
Baker Hughes IP mapOpen innovation space following US8022118B2 invalidation
The removal of US8022118B2 from the active patent landscape creates potential freedom-to-operate in previously covered drag-reduction approaches for asphaltenic crude. Adjacent white-space areas — such as novel DRA polymer architectures, biobased drag reducers, or multifunctional asphaltene-inhibiting DRA blends — may represent viable R&D directions with reduced IP risk.
