"Passing off and unfair competition": an event review
This post was written by guest Kat Nadia, and posted by Jeremy
"Passing Off and Unfair Competition", hosted by Baker & McKenzie LLP, was the subject of the third event held by the Journal of Intellectual Property Law & Practice (JIPLP) in conjunction with its German partners at GRUR Int.
Passing off
The first talk came from Ben Allgrove, a partner at Baker & McKenzie and a contributor to JIPLP. Ben's main message revolved around two propositions; (i) that the tort of passing off is flexible and that it has evolved over time; an evolution that is still progressing to this day, and (ii) in the core area of practice there is no real difference between passing off and unfair competition.

The basics

Early development
The point of an evolving concept was illustrated further by reference to the leading case of Cadbury Schweppes Pty Ltd v Pub Squash Co. Pty Ltd [1980] UKPC 30, which showed early on that it was acknowledged that the concept of passing off could even extend to advertising campaigns. Cadbury Schweppes launched a lemon drink in Australia which was novel in that it was specifically aimed at the adult male market. Pub Squash Co copied the drink itself and the general theme and tone of the marketing campaign. Even though Cadbury Schweppes failed to establish passing off, there was at least some acknowledgment that passing off could happen in advertising.
Extended passing off
Ben next reviewed the three different ways in which passing off has been extended.
1. Initial Interest confusion is a concept which was derived from US law. The doctrine was defined by the International Trademark Association (INTA) as
'... a doctrine which has been developing in U.S. trademark cases since the 1970s, which allows for a finding of liability where a plaintiff can demonstrate that a consumer was confused by a defendant’s conduct at the time of interest in a product or service, even if that initial confusion is corrected by the time of purchase'

The next step in this evolution is post-sale confusion. In L'Oréal SA v Bellure NV [2010] EWCA Civ 535 (on which see IPKat overview here) Bellure's business model was to sell cheap 'knock off' perfumes whose smell alluded to the smell of L'Oréal 's own perfumes. Even though there was no confusion pre-sale and at the point of trade as consumers knew what they were buying and who they were buying from, it was found there was post sale confusion and therefore there was unfair advantage.
2 The tort of passing off has now been extended to the reputation and goodwill held in products via quality association. The key components come from the ‘Advocaat’ case (Erven Warnink B.V. v J. Townend & Sons (Hull) Ltd [1979] AC 731) Lord Diplock established five criteria for a claim of extended passing off. There must be:

1. Misrepresentation
2. by a trader in the course of trade
3. to prospective customers of his or ultimate consumers of goods or services supplied by him
4. which is calculated to injure the business or goodwill of another trader and
5. which causes actual damage to the business or goodwill of the trader bringing the action.
In the recent ‘ Vodkat’ case, Diageo North America Inc v Intercontinental Brands (ICB) Ltd [2010] EWHC 17 (Ch), Arnold J held that "vodka" is a term that is capable of distinguishing a particular class and quality of product. In branding a vodka blend as "VODKAT" and marketing it in a manner that did not make clear to the public that this was not vodka, the judge held Intercontinental Brands liable for passing off.
More recently in the long-awaited appeal in Fage UK Ltd & Another v Chobani UK Ltd & Another [2014] EWCA Civ 5 (see IPKat overview here) the argument focused on whether Chobani could use the term ‘Greek yoghurt' to describe their yoghurt. The Court of Appeal, upholding the trial judgment, sided with Fage in finding that 'Greek yoghurt' had to be made in Greece.

Colour
The Irish case of BP Amoco PLC v John Kelly Ltd and Glenshane Tourist Services Ltd (Court of Justice in Northern Ireland, Chancery Division, 16 June 2000, here) involved a dispute over the colour green. Here BP claimed that the second defendant, which ran a filling station under the ‘TOP’ brand used the same colour green as them, and argued that members of the public would be confused into thinking their garage was a BP garage. In this case passing off failed as the court stated petrol is a commodity product and a consumer would not drive away. There would thus have to be a pretty strong association with a colour, and it is very difficult to show pre-sale confusion. It was noted that in a supermarket for example, cheaper brands often use the same colouring as bigger competing brands.
German unfair competition law
The second talk was presented by Gert Würtenberger (a partner at Würtenberger Kunze, Munich) on the topic of German Unfair Competition Law.
After the industrialisation and liberalisation of the market, Gert explained, Germany passed its first law in unfair competition in 1896. However problems were still evolving, so Germany reacted and passed a revised Unfair Competition Act 1909 ("the Act”).

At first instance, the trade association argued that the brewing company was deceiving consumers by not indicating that this specific beer was not brewed in Warsteiner, which was found to be misleading. The brewing company then put a small indication on the front of the bottle, which was deemed to be too small. Finally the Supreme Court referred questions to the CJEU to see whether the directive could take influence from case law on geographical indications. In its final decision the Supreme Court made a complete turnaround on its opinion regarding the labelling and stated, that if the consumer is interested where the beer is brewed, the consumer will look on the front and the back of the bottle.
Section 4 of the Act gives examples of unfair commercial practices; however, the list is not final. Section 4(9) is the closest to passing off in UK law in which it states, ‘Unfairness shall have occurred in particular where a person offers goods or services that are replicas of goods or services of a competitor if he
(a) causes avoidable deception of the purchaser regarding their commercial origin;
(b) unreasonably exploits or impairs the assessment of the replicated goods or services; or
(c) dishonestly obtained the knowledge or documents needed for the replicas.’

Comparison
There seem to be a variety of similarities between the two doctrines of passing off and unfair competition. However, some have suggested that the UK tort of passing off is unfair competition in all but name.
During the panel discussion featuring His Honour Judge Richard Hacon QC, Dr Birgit Clark and Professors Phillip Johnson and Christopher Wadlow, it was suggested that there are still differences between the two concepts, mainly the fact that unfair competition has more of a consumer protection element, whereas passing off is more business-to-business and competitor-to-competitor.
