SHEET 02 · THE ROLE
What Does a Chemical Engineering Expert Witness Do?
A chemical engineering expert witness reviews the technical record in a dispute, forms an independent opinion and defends it in a written report and under oath. The record can include plant data, lab results, mass balances, credit filings, contracts and valuations. The opinion explains what that record supports, in terms a court can follow.
Counsel retain us in two roles. As a consulting expert, we review the merits before a complaint is filed or an expert is designated, so the case rests on engineering that will hold. As a testifying expert, we write the report and rebuttals and sit for deposition.
Our work covers the chemical, energy and renewable energy sectors, including the commercial questions that sit on top of the engineering: markets, competing products, regulation and value.
SHEET 03 · DISPUTES WE TAKE
Disputes We Take
Eight kinds of matter. Each turns on a technical question that a generalist expert can describe and an operator can test.
M-01 · INTELLECTUAL PROPERTY
Intellectual Property in Chemicals and Materials
THE QUESTION
The market a technology serves, how it differs from the alternatives and what that difference is worth.
WHAT WE TEST
Technical specifications against real applications, the buyers each product wins, regulatory fit and market size.
M-02 · VALUATION
Valuation and Investment Disputes
THE QUESTION
What a company, asset or credit portfolio was worth, and whether investors were told the truth about it.
WHAT WE TEST
Offtake agreements and LOIs, public market comparables, sector conditions and the technical claims made to investors.
OUR POSITION
A valuation is an opinion of value under stated assumptions. It is not a price any investor must pay, and in an emerging sector, sentiment can move the price well above or below it.
M-03 · PERFORMANCE
Technology Performance and Scale-Up Representations
THE QUESTION
Whether a plant or process delivered the yield, throughput, uptime or specification promised, and what the pilot data supported when capital was raised.
WHAT WE TEST
Plant data and lab results reconciled against the design basis and the guarantee, plus run length, balance closure and scale-up ratio against the evidence thresholds we apply.
M-04 · TRANSACTIONS
Transaction and Financing Disputes
THE QUESTION
Whether technical representations in an acquisition, private credit facility or earn-out were accurate.
WHAT WE TEST
Data room claims against operating records, and output-linked earn-out calculations against what the plant could physically produce.
M-05 · CREDITS
Renewable Fuel and Carbon Credit Disputes
THE QUESTION
Whether credits were validly generated, delivered and reported under the Renewable Fuel Standard, a Low Carbon Fuel Standard, Section 45Z or a voluntary registry.
WHAT WE TEST
Feedstock pathway, carbon intensity, volumes, EMTS and QAP records, and delivery terms. As a biofuel expert witness we bring two decades on the generating side: in the RIN market since 2007 and the LCFS market since 2012.
M-06 · FEEDSTOCK
Feedstock and Supply Contract Disputes
THE QUESTION
Whether delivered feedstock met specification, and who bears the cost when it did not.
WHAT WE TEST
Certificates of analysis, free fatty acid, moisture and impurities against contract specifications, and the pretreatment losses that followed. The plants we ran handled brown grease at up to 100% FFA.
M-07 · ENVIRONMENTAL
Environmental and Emissions Compliance
THE QUESTION
Whether a facility's process and controls could meet its permit, and why they did not.
WHAT WE TEST
Process data, emissions calculations and control equipment performance against permit conditions.
M-08 · PRODUCT CLAIMS
Product and Consumer Claims
THE QUESTION
Whether a chemical ingredient, material or component performed as specified and was represented accurately.
WHAT WE TEST
Formulation and process records, analytical results and specifications against the claims made to buyers and consumers.
SHEET 04 · THE RECORD
Six Records That Decide a Technical Dispute
Most technical disputes are won or lost on a small set of records. Each one proves something specific, and each has a known way of breaking under cross-examination.
R-01
Plant historian and control-system data
PROVES
What the plant actually did, hour by hour.
BREAKS
When tags were re-ranged, instruments drifted or data was averaged before export.
R-02
Lab certificates of analysis
PROVES
Product and feedstock quality at the moment of sampling.
BREAKS
When the sample point, method or lab changed, or one good certificate stands in for a whole lot.
R-03
Mass and energy balances
PROVES
Whether a claimed yield is physically possible.
BREAKS
When unaccounted material is left out. Closure worse than ±5% does not support a yield claim.
R-04
EMTS RIN records and QAP reports
PROVES
Which credits were generated, transferred and retired.
BREAKS
When the feedstock pathway or volume behind a RIN does not match the plant's own records.
R-05
Pilot reports and investor decks
PROVES
What management knew and said at the time.
BREAKS
When short runs on clean feed were presented as commercial readiness.
R-06
Offtake LOIs and supply contracts
PROVES
Demand and price support behind a valuation or business plan.
BREAKS
When a letter of intent is non-binding, conditional or priced off a market that has since moved.

DAUBERT MOTIONS, EXCLUSIONS OR LIMITS ON HIS TESTIMONY
How Our Opinions Are Built
Federal Rule of Evidence 702, as amended on 1 December 2023, requires the party offering an expert to show that the opinion rests on sufficient facts, reliable methods and a reliable application of those methods to the case. We build every opinion to that standard.
Each conclusion traces to a document, dataset or calculation in the record. We use established methods such as mass and energy balances and market comparables, state every assumption, test how far the answer moves when an assumption changes, and rule out other explanations before settling on one.

SHEET 06 · QUESTIONS
Chemical Engineering Expert Witness FAQs
Should counsel retain a chemical engineering expert before filing?
Yes, where the case turns on technical facts. An early review shows which claims the engineering record supports before positions are pleaded. Under Federal Rule of Civil Procedure 26(b)(4)(D), a consulting expert retained in anticipation of litigation is generally shielded from discovery, and counsel decides later whether to designate a testifying expert.
Can a chemical engineer testify on valuation and investment disputes?
Yes, where value depends on technology. Our principal has sat on VC investment committees and valued energy companies. A valuation is an opinion of value under stated assumptions. It is not a price any investor must pay, and in an emerging sector, sentiment can move that price well above or below it.
Do you handle disputes over RINs, LCFS credits and Section 45Z?
Yes. We have been in the RIN market since 2007 and the LCFS market since 2012, and we have run plants that generate these credits. We test whether feedstock pathways, carbon intensity, volumes and EMTS records support the credits that were claimed, delivered or reported.
How long does a chemical engineering expert report take?
Typically three to four weeks from receipt of the record, and six to eight weeks for complex matters with large data sets or several technical questions. Rebuttal reports follow the opposing expert's report, and deposition preparation runs to counsel's schedule.
How are chemical engineering expert witness fees structured?
Engagements begin with a retainer, agreed once the conflict check clears. Fees then follow the work on the matter: record review, analysis, reports, deposition preparation and testimony. The full structure is set out in the engagement letter before substantive work starts, and we discuss it on the first call with counsel.
Do you work for plaintiffs or defendants?
Both. We have been retained by plaintiffs and by defendants. Our opinion follows the engineering record and the market evidence, whichever side retains us, and we tell counsel early when the record does not support the position they hoped to take.
Which sectors and disputes do you cover as a chemical litigation consultant?
Chemical, energy and renewable energy disputes: intellectual property, valuation and investment, technology performance, transactions, renewable fuel and carbon credits, feedstock supply, environmental compliance and product claims. We act as a consulting expert before filing and as a testifying expert after designation.
