Factual and Procedural Background
The principal claim in these proceedings is brought by the Plaintiff against multiple Defendants for misuse of confidential information relating to the design of a half-size wind tunnel model of a Formula 1 ("F1") racing car, alongside a claim for infringement of copyright. Issues of liability and quantum were unusually tried together following a court order. The Fourth Defendant has a cross-claim against the Plaintiff for an unpaid debt.
The Defendants do not dispute some copying of the Plaintiff's confidential CAD design files by employees of one Defendant company. The disputes concern the extent of copying, its actionability, which Defendants are liable, and the quantum of damages.
The Plaintiff operates an F1 racing team with a history of name changes and owns a wind tunnel facility at Brackley near Silverstone.
The First and Second Defendants are a Malaysian company and its English subsidiary operating an F1 racing team, known as Lotus at the relevant time, now Caterham F1.
The Third Defendant is an individual with extensive experience in F1 technical roles, including a former role as Chief Technical Officer of the Plaintiff until contract termination in 2008.
The Fifth Defendant and its subsidiary Aerolab are Italian companies specialising in aerodynamic development and wind tunnel testing, having worked for several F1 teams including the Plaintiff and Lotus.
The relationship between the Plaintiff and Aerolab began around 2006, with Aerolab engaged under a development contract from April 2008 to December 2009, which included confidentiality and exclusivity provisions. Aerolab was obliged to keep all information confidential and to use it solely for the Plaintiff’s benefit.
Payment disputes arose in 2009, with the Plaintiff defaulting on fees owed to Aerolab, leading Aerolab to cease work for the Plaintiff on 31 July 2009 and subsequently commence work for Lotus from 3 August 2009, initially under FondTech with Aerolab as subcontractor.
The Plaintiff discovered the cessation of work and severance of server connections in mid-August 2009, and Aerolab initiated legal proceedings in Italy to secure its unpaid fees.
Lotus submitted its application for entry into F1 in August 2009 and was accepted in September 2009. Aerolab and FondTech designed and built initial wind tunnel models for Lotus from August 2009, with extensive aerodynamic development continuing through late 2009 and early 2010.
The Plaintiff alleges that Aerolab and FondTech misused its confidential CAD files in designing the Lotus model, and that the Third Defendant, acting for Lotus, is liable for breach of confidence and inducement of breach.
Claims for infringement of Community and UK design rights were not pursued. The copyright claim is limited to UK copyrights against the English subsidiary Defendant.
The court heard extensive factual and expert evidence, including on the nature of confidential information, copying, and quantum of damages.
Legal Issues Presented
- Whether the Defendants misused the Plaintiff’s confidential information and breached contractual and equitable obligations of confidence.
- Whether the Third Defendant is liable for breach of confidence as an accessory or for inducing breach.
- The extent of liability of the corporate Defendants, including the English subsidiary.
- The scope and duration of confidentiality obligations post-termination of the Development Contract.
- The validity and extent of the Plaintiff’s copyright infringement claim.
- The appropriate measure and quantum of damages or equitable compensation for the breaches found.
Arguments of the Parties
Plaintiff's Arguments
- The Plaintiff contended that Aerolab and FondTech misused confidential CAD files containing precise dimensions and design details of aerodynamic parts, which were not publicly available.
- The Plaintiff alleged that the Third Defendant agreed with Aerolab’s principal to use the Plaintiff's confidential information to design the Lotus model.
- The Plaintiff argued that confidentiality obligations continued after termination of the Development Contract.
- On quantum, the Plaintiff claimed damages based on the development costs of its 2009 model, asserting the confidential information was of great value, including the aerodynamic system, track validation, and stable baseline.
- The Plaintiff maintained that the hypothetical negotiation for a licence fee would have been with Lotus, a competitor, and would reflect the full value of the misused information.
Defendants' Arguments
- The Defendants accepted some copying by CAD draftsmen but argued it was limited, opportunistic, and did not involve misuse of aerodynamicists’ confidential information.
- The Third Defendant and Aerolab denied any agreement to misuse confidential information and denied liability for breach of confidence.
- They argued that confidentiality obligations did not extend indefinitely post-termination or were limited to trade secrets only.
- The Defendants contended the Plaintiff’s confidential information was largely in the public domain or trivial and that the Force India 2009 car was the least competitive, limiting the value of any information.
- On damages, the Defendants submitted the value of the misused information was modest, reflecting only time saved by CAD draftsmen, and suggested a range of minimal licence fees based on man-hours and market rates.
- The Defendants maintained the hypothetical negotiation would be between the Plaintiff and Aerolab/FondTech, not Lotus.

Court's Reasoning and Analysis
The court carefully examined the facts, expert evidence, and contractual terms to determine whether confidential information was misused and by whom. It distinguished between copying by CAD draftsmen as shortcuts and misuse by aerodynamicists in design creation. The court found that Aerolab and FondTech’s CAD draftsmen did misuse confidential information by copying Force India CAD files to save time, but the aerodynamicists largely relied on their own skill and knowledge.
The court accepted that the confidentiality obligations in the Development Contract, particularly clause 5(b), survive termination and apply indefinitely, covering all confidential information not in the public domain.
It rejected the Plaintiff’s claim that the Third Defendant agreed to or induced misuse of confidential information, finding no direct or persuasive circumstantial evidence of such an agreement. The court also found no accessory liability based on turning a blind eye, as the Third Defendant was unaware of misuse at the time and took reasonable steps thereafter.
The court held that the Plaintiff’s claim against the corporate Defendant Lotus depended on the Third Defendant’s liability and therefore failed with that claim.
On copyright, the court found that certain parts of the Lotus CAD files reproduced substantial parts of the Plaintiff’s CAD files, establishing infringement to a limited extent.
Regarding damages, the court analysed the complex principles governing compensation for breach of confidence and intellectual property infringement, emphasizing that damages should be compensatory and reflect the value of the misused information. It rejected the Plaintiff’s claim for damages based on the full development cost of the 2009 model as disproportionate and unsupported.
The court accepted that the misused information was of limited value, mainly reflecting time saved by CAD draftsmen taking shortcuts. It determined the hypothetical negotiation date as early August 2009, when misuse began, and identified the parties as the Plaintiff and Aerolab/FondTech, not Lotus.
Taking all evidence into account, including expert testimony and the limited extent of misuse, the court fixed the reasonable licence fee at £25,000, a sum deemed fair, proportionate, and dissuasive.
Holding and Implications
The court held that:
- The Plaintiff’s claim for breach of confidence succeeds against Aerolab and FondTech in respect of specific aerodynamic and mechanical parts as identified, but fails against the Third Defendant and Lotus.
- The Plaintiff’s claim for copyright infringement succeeds against the English subsidiary Defendant only in respect of certain parts.
- The Plaintiff is entitled to damages/equitable compensation of £25,000 from Aerolab and FondTech.
- The Plaintiff owes Aerolab £846,230 under the Development Contract, and this sum is to be set off by the £25,000 awarded to the Plaintiff.
The direct effect is that the Plaintiff recovers limited damages and the Defendants recover the unpaid debt subject to set off. No broader precedential implications were established, as the court applied established principles of breach of confidence, contract interpretation, and damages assessment without extending legal doctrine.
