1. Mars' copyright and database right in the Coin Set Data by (a) reproducing lower limits and window widths in the course of developing its reprogramming software and (b) reproducing window widths in its reprogramming software and in customers' mechanisms which it has reprogrammed.
2. Mars' copyright in the Discrimination Algorithms and in the Program Code which implements the Discrimination Algorithms by reproducing the Discrimination Algorithms in its reprogramming software.
3. Mars' copyright in the Program Code which implements the HII serial communications protocol by reproducing the HII message structures and contents in its reprogramming software.
4. Mars' copyright in the Program Code by making transient copies of the Code during the course of developing and operating its reprogramming software.
On that basis Mars no longer advance a case under s.296. Nor do any issues arise as to whether Teknowledge's work results in inferior re-calibration. More generally, however, Teknowledge accept that if some-one were to make a poor job of reverse engineering that could, in principle, lead to badly re-programmed discriminators and hence to security problems of the sort whereby machines would pass slugs. This point was said to be relevant to Mars' attack on the applicability of the British Leyland defence but in the end I think it is not.
"it knew and understood that the Claimant had included encryption within the Cashflow device and that by so introducing such encryption the Claimant was seeking to restrict persons from assessing and analysing how the Cashflow mechanism operated, but nothwithstanding such encryption the Defendant believed at all material times that it was entitled to assess and analyse the Cashflows the subject of this action."
For some reason I could not understand, Mars were not satisfied with this admission and so Messrs Rawding and, particularly Mr Hogan, were cross-examined on the point. Their evidence merely confirmed the admission.
1. Whether there is a common law defence to the otherwise conceded claims for copyright infringement and mis-use of data.
2. Whether the defendant's activities by way of reverse engineering amount to a breach of confidence in law.
3. Whether, if so, the common law defence applicable to (1) also applies to breach of confidence.
The British Leyland defence - is "re-calibration" within it?
"features of shape or configuration of an article which-
(i) enable the article to be connected to, or placed in, around or against another article so that either article may perform its function, or
(ii) are dependent upon the appearance of another article of which the article is intended by the designer to form an integral part."
This "must fit or must match" exception will cover some spare parts but not others, depending on how necessary it is to copy. It seems to me clear that in those circumstances Parliament has recently specifically considered the problem of spares - whereas under the 1911 and 1956 Acts it was really a legislative and judicial accident that they were covered and indeed no-one even so suggested until the 1970s. So, in relation to design right, it would clearly be wrong for the courts to invent any spare part exception. That would be to legislate.
"Nothing in this paragraph affects the operation of any rule of law preventing or restricting the enforcement of copyright in relation to a design"
That has the effect of retaining the Leyland defence, which of course remained necessary in respect of pre-Act drawings for a period of 10 years. Were this not done, Armstrong and others would have had to stop making spares.
"Nothing in this Part affects any rule of law preventing or restricting the enforcement of copyright, on grounds of public interest or otherwise."
"Cannot be regarded as truly founded upon any principle of the law of contract or property. It is instead an expression of what the House perceived as overriding public policy, namely the need to prevent a manufacturer from using copyright (as opposed to patents or design right) in order to control the aftermarket in spare parts."
"It is of course a strong thing (not to say constitutionally questionable) for a judicially-declared head of public policy to be treated as overriding or qualifying an express statutory right. Their Lordships therefore think that the prospect of any extension of the British Leyland exception should be treated with some caution."
Breach of Confidence
"First, the information itself, in the words of Lord Greene MR in the Saltman case on p.215, must 'have the necessary quality of confidence about it.' Secondly, that information must have been imparted in circumstances importing an obligation of confidence. Thirdly there must be an unauthorised use of that information to the detriment of the party communicating it."
This formulation has received high approval, e.g. through Lord Griffiths in Spycatcher (AG v Guardian [1990] 1 AC 109 at p.168).
"It seems to me that if the circumstances are such that any reasonable man standing in the shoes of the recipient of the information would have realised that upon reasonable grounds the information was being given to him in confidence, then that should suffice to impose upon him the equitable obligation of confidence."
Megarry J was contemplating a case of an actual transfer of information from one man to another: this case is just about finding out information from a product on the market. I do not think doing that would be regarded as anything other than fair game for competitors.
"I start with the broad general principle (which I do not intend in any way to be definitive) that a duty of confidence arises when confidential information comes to the knowledge of a person (the confidant) in circumstances where he has notice, or is held to have agreed, that the information is confidential, with the effect that it would be just in all the circumstances that he should be precluded from disclosing the information to others. I have used the word "notice" advisedly, in order to avoid the (here unnecessary) question of the extent to which actual knowledge is necessary; though I of course understand knowledge to include circumstances where the confidant has deliberately closed his eyes to the obvious. The existence of this broad principle reflects the fact that there is such a public interest in the maintenance of confidences, that the law will provide remedies for their protection.
I realise that, in the vast majority of cases, in particular those concerned with trade secrets, the duty of confidence will arise from a transaction or relationship between the parties - often a contract, in which event the duty may arise by reason of either an express or an implied term of that contract. It is in such cases as these that the expressions "confider" and "confidant" are perhaps most aptly employed.. But it is well settled that a duty of confidence may arise in equity independently of such cases; and I have expressed the circumstances in which the duty arises in broad terms, not merely to embrace those cases where a third party receives information from a person who is under a duty of confidence in respect of it, knowing that it has been disclosed by that person to him in breach of his duty of confidence, but also to include certain situations, beloved of law teachers - where an obviously confidential document is wafted by an electric fan out of a window into a crowded street, or where an obviously confidential document, such as a private diary, is dropped in a public place, and is then picked up by a passer-by"
Mars rely upon Lord Goff's reference to an "obviously confidential document" fortuitously coming into the hands of a non-intended recipient. English and American Insurance v Herbert Smith [1988] FSR 232 is an actual example of that. But this case is in no way comparable. The recipient (the customer) is an intended recipient of the article containing the information.. There is nothing obviously confidential about the machine he gets. There is no marking "confidential" and indeed there is not even any indication of encryption. By the time one gets to find out about the encryption it is, in my judgment, far too late to impose a duty of confidence. I do not think even an express statement would work to override the buyer's entitlement to find out how his machine worked.

MR. JUSTICE JACOB:
"In deciding what order (if any) to make about costs, the court must have regard to all the circumstances, including --
(a) the conduct of all the parties;
(b) whether a party has succeeded on part of his case, even if he has not been wholly successful; and
(c) any payment into court or admissible offer to settle made by a party which is drawn to the court's attention (whether or not made in accordance with Part 36)."
"(a) conduct before, as well as during, the proceedings, and in particular the extent to which the parties followed any relevant pre-action protocol;
(b) whether it was reasonable for a party to raise, pursue or contest a particular allegation or issue;
(c) the manner in which a party has pursued or defended his case or a particular allegation or issue;
(d) whether a claimant who has succeeded in his claim, in whole or in part, exaggerated his claim."
(Liberty to apply, leave to appeal on costs and substantive issues).
