“(1) A registered trade mark is a property right obtained by the registration of the trade mark under this Act and the proprietor of a registered trade mark has the rights and remedies provided by this Act. (2) No proceedings lie to prevent or recover damages for the infringement of an unregistered trade mark as such; but nothing in this Act affects the law relating to passing off.”
“Neither the appellants nor the respondents contend that the principles of law are in any doubt. The law of passing off can be summarised in one short general proposition—no man may pass off his goods as those of another. More specifically, it may be expressed in terms of the elements which the plaintiff in such an action has to prove in order to succeed. These are three in number. First, he must establish a goodwill or reputation attached to the goods or services which he supplies in the mind of the purchasing public by association with the identifying "get-up" (whether it consists simply of a brand name or a trade description, or the individual features of labelling or packaging) under which his particular goods or services are offered to the public, such that the get-up is recognised by the public as distinctive specifically of the plaintiff's goods or services. Secondly, he must demonstrate a misrepresentation by the defendant to the public (whether or not intentional) leading or likely to lead the public to believe that goods or services offered by him are the goods or services of the plaintiff. Whether the public is aware of the plaintiff’s identity as the manufacturer or supplier of the goods or services is immaterial, as long as they are identified with a particular source which is in fact the plaintiff. For example, if the public is accustomed to rely upon a particular brand name in purchasing goods of a particular description, it matters not at all that there is little or no public awareness of the identity of the proprietor of the brand name. Thirdly, he must demonstrate that he suffers or, in a quia timet action, that he is likely to suffer damage by reason of the erroneous belief engendered by the defendant's misrepresentation that the source of the defendant's goods or services is the same as the source of those offered by the plaintiff.”
“55. The elements necessary to reach a finding of passing off are the ‘classical trinity' of that tort as described by Lord Oliver in the Jif Lemon case (Reckitt & Colman Product v Borden[1990] 1 WLR 491 HL,[1990] RPC 341 , HL), namely goodwill or reputation; misrepresentation leading to deception or a likelihood of deception; and damage resulting from the misrepresentation. The burden is on the Claimants to satisfy me of all three limbs.”
“To establish a likelihood of deception or confusion in an action for passing off where there has been no direct misrepresentation generally requires the presence of two factual elements: (1) that a name, mark or other distinctive feature used by the plaintiff has acquired a reputation among a relevant class of persons; and (2) that members of that class will mistakenly infer from the defendant’s use of a name, mark or other feature which is the same or sufficiently similar that the defendant’s goods or business are from the same source or are connected. While it is helpful to think of these two factual elements as successive hurdles which the plaintiff must surmount, consideration of these two aspects cannot be completely separated from each other, as whether deception or confusion is likely is ultimately a single question of fact In arriving at the conclusion of fact as to whether deception or confusion is likely, the court will have regard to: (a) the nature and extent of the reputation relied upon; (b) the closeness or otherwise of the respective fields of activity in which the plaintiff and the defendant carry on business; (c) the similarity of the mark, name etc. used by the defendant to that of the plaintiff; (d) the manner in which the defendant makes use of the name, mark etc. complained of and collateral factors; and (e) the manner in which the particular trade is carried on, the class of persons who it is alleged is likely to be deceived and all other surrounding circumstances.”
“26. How reluctant should an appellate court be to interfere with the trial judge's evaluation of, and conclusion on, the primary facts? As Hoffmann L.J. made clear in Grayan there is no single standard which is appropriate to every case. The most important variables include the nature of the evaluation required, the standing and experience of the fact-finding judge or tribunal, and the extent to which the judge or tribunal had to assess oral evidence. 27. It is worth noting that Biogen was a case very close to the top end of the scale. It involved very complex biotechnology which was the subject of a lot of expert evidence given at a lengthy trial before a very experienced judge of the Patents Court. In the circumstances Lord Hoffmann's memorable reference to Renan was not (if I may respectfully say so) out of place. There are far fewer nuances to be picked up from a bundle of statutory declarations which contain a good deal of irrelevant or tendentious material and on which there is no cross-examination. 28. In this case the hearing officer had to make what he himself referred to as a multi-factorial comparison, evaluating similarity of marks, similarity of goods and other factors in order to reach conclusions about likelihood of confusion and the outcome of a notional passing-off claim. It is not suggested that he was not experienced in this field, and there is nothing in the Civil Procedure Rules to diminish the degree of respect which has traditionally been shown to a hearing officer's specialised experience. (It is interesting to compare the observations made by Lord Radcliffe in Edwards v Bairstow [1956] A.C. 14 at pp.38–39, about the general commissioners, a tribunal with a specialised function but often little specialised training.) On the other hand the hearing officer did not hear any oral evidence. In such circumstances an appellate court should in my view show a real reluctance, but not the very highest degree of reluctance, to interfere in the absence of a distinct and material error of principle.”
“26. The following principles also apply to those parts of the judgment which contain findings of fact or evaluations of factual evidence: Findings of fact i) An appeal court will only interfere with a trial judge’s finding of fact and thus allow an appeal on the basis of a challenge where it properly determines that the finding of fact is unsupported by the evidence or where the decision is one which no reasonable judge could have reached - see Haringey LBC v Ahmed & Ahmed[2017] EWCA Civ 1861 , CA, at [29]–[31]; Henderson v Foxworth Investments Ltd[2014] UKSC 41 ; [2014] 1 W.L.R. 2600 at [62] and Hamilton v Allied Domecq Plc[2006] SC 221 at [85]. Evaluation of factual evidence ii) An appellate court must be cautious in reversing a trial judge’s evaluation of facts, just as it must be in reversing a primary finding of fact (per Lord Hoffmann in Biogen Inc v Medeva Plc [1997] R.P.C. 1 at 45). This is because where a judge’s evaluation of facts is challenged, it is properly understood to be very difficult for an appellate court to place itself in the position of the trial judge who would have had to take account of both written and oral evidence. The reasons for this approach are summarised in Fage UK Ltd v Chobani UK Ltd[2014] EWCA Civ 5 at [114]–[115]. iii) The proper approach on a challenge to an evaluative decision of a first instance judge is that “the appeal court does not carry out a balancing task afresh but must ask whether the decision of the judge was wrong by reason of some identifiable flaw in the judge’s treatment of the question to be decided, ‘such as a gap in logic, a lack of consistency, or a failure to take account of some material factor, which undermines the cogency of the conclusion’” – see Prescott v Potamianos[2019] EWCA Civ 932 in a judgment of the court (McCombe, Leggatt and Rose LJJ) at [76].”
“29. The appellate court should not treat a judgment or written decision as containing an error of principle simply because of its belief that the judgment or decision could have been better expressed. The duty to give reasons must not be turned into an intolerable burden: see the recent judgment of this court in English v Emery Reimbold & Strick Ltd (and two other appeals heard with it)[2002] EWCA Civ 605 , April 30, 2002 , para.19: “… the judgment must enable the appellate court to understand why the judge reached his decision. This does not mean that every factor which weighed with the judge in his appraisal of the evidence has to be identified and explained. But the issues the resolution of which were vital to the judge's conclusion should be identified and the manner in which he resolved them explained. It is not possible to provide a template for this process. It need not involve a lengthy judgment. It does require the judge to identify and record those matters which were critical to his decision.” “… the judgment must enable the appellate court to understand why the judge reached his decision. This does not mean that every factor which weighed with the judge in his appraisal of the evidence has to be identified and explained. But the issues the resolution of which were vital to the judge's conclusion should be identified and the manner in which he resolved them explained.

“where a trader adopts words in common use for his trade name, some risk of confusion is inevitable. But that risk must be run unless the first user is allowed unfairly to monopolise the words. The Court will accept comparatively small differences as sufficient to avert confusion. A greater degree of discrimination may fairly be expected from the public where a trade name consists wholly or in part of words descriptive of the articles to be sold or the services to be rendered.”
