Cadbury retains hold over its trademarked shade of purple

Pantone 2685 is Cadbury's special colour.

After fighting for almost eight years, Cadbury has finally won a high court battle over its trademark of a certain shade of the colour purple.

The chocolate company applied for the trademark back in October 2004, registering:

The colour purple (Pantone 2685C), as shown in the form of application, applied to the whole visible surface or being the predominant colour applied to the whole visible surface, of the packaging of the goods [for] chocolate in bar and tablet form, chocolate confectionery, chocolate assortments, cocoa-based beverages, chocolate-based beverages, preparations for chocolate-based beverages, chocolate cakes.

Pantone 2685C is also represented by the hex colour code #3B0084, or RGB 59-0-132. Cadbury has got a lot of stick over the intervening eight years for, effectively, trademarking a certain wavelength of the electromagnetic spectrum, but the protected aspect is actually much narrower than has previously been reported. Anyone can use the purple for anything non-chocolate-related, and even other chocolate manufacturers can use it provided it isn't "the predominant colour applied to the whole visual surface" of the packaging.

Nonetheless, Nestlé, Cadbury's biggest rival, opposed the trademark. Their legal argument was that that shade of purple had no distinctive character, had been granted for too broad a range of goods, and had been applied for in bad faith, claiming that Cadbury never intended to use the mark for "the whole visible surface". In addition, Nestlé can't have avoided noticing that one of its own subsidiaries, Wonka, uses an eerily similar shade of purple in its own branding (although Wonka's is #5C2A88). Nestlé won in part, with the Intellectual Property Office ruling that Cadbury's trademark would only apply to chocolate bars and drinking chocolate, but their appeal against even that aspect is what was finally overturned yesterday, when the High Court ruled that the colour has been distinctive of Cadbury for milk chocolate since 1914.

A Cadbury spokesman told Design Week:

We welcome the decision of the High Court which allows us to register as a Trade Mark and protect our famous Colour Purple across a range of milk chocolate products. Our Colour Purple has been linked with Cadbury for more than a century and the British public have grown up understanding its link with our chocolate.

Colour protections are not unique to chocolate bars, but they have had varying degrees of success in other areas. BP attempted to trademark Pantone 348C, a shade of green, in over 20 countries, but slowly had to back away. In Britain, it lost a case it brought in 2000 against a Northern Irish oil company which was also using green on its petrol stations, and has since effectively abandoned Pantone 348C by redefining "BP Green", which is now officially Pantone 355C.

The Easy conglomerate, owners of the travel company easyJet, uses Pantone 021C, but famously got into trouble with the mobile phone company Orangewhich has trademarked the similar shade Pantone 151C – when it started easyMobile in 2004.

It's important to note, though, that all of these protections are specific to sectors. As the BBC put it:

Cadbury's, for example, can argue that their famous shade of purple cannot be used by other chocolate makers. They could not stop a firm making hats from using the same shade though, as they would be in different businesses.

Wearing Cadbury's purple would probably be a bit of a fashion faux-pas, but it's not actually illegal yet.

Theresa May’s Brexit speech is Angela Merkel’s victory – here’s why

The Germans coined the word “merkeln to describe their Chancellor’s approach to negotiations. 

It is a measure of Britain’s weak position that Theresa May accepts Angela Merkel’s ultimatum even before the Brexit negotiations have formally started

The British Prime Minister blinked first when she presented her plan for Brexit Tuesday morning. After months of repeating the tautological mantra that “Brexit means Brexit”, she finally specified her position when she essentially proposed that Britain should leave the internal market for goods, services and people, which had been so championed by Margaret Thatcher in the 1980s. 

By accepting that the “UK will be outside” and that there can be “no half-way house”, Theresa May has essentially caved in before the negotiations have begun.

At her meeting with May in July last year, the German Chancellor stated her ultimatum that there could be no “Rosinenpickerei” – the German equivalent of cherry picking. Merkel stated that Britain was not free to choose. That is still her position.

Back then, May was still battling for access to the internal market. It is a measure of how much her position has weakened that the Prime Minister has been forced to accept that Britain will have to leave the single market.

For those who have followed Merkel in her eleven years as German Kanzlerin there is sense of déjà vu about all this.  In negotiations over the Greek debt in 2011 and in 2015, as well as in her negotiations with German banks, in the wake of the global clash in 2008, Merkel played a waiting game; she let others reveal their hands first. The Germans even coined the word "merkeln", to describe the Chancellor’s favoured approach to negotiations.

Unlike other politicians, Frau Merkel is known for her careful analysis, behind-the-scene diplomacy and her determination to pursue German interests. All these are evident in the Brexit negotiations even before they have started.

Much has been made of US President-Elect Donald Trump’s offer to do a trade deal with Britain “very quickly” (as well as bad-mouthing Merkel). In the greater scheme of things, such a deal – should it come – will amount to very little. The UK’s exports to the EU were valued at £223.3bn in 2015 – roughly five times as much as our exports to the United States. 

But more importantly, Britain’s main export is services. It constitutes 79 per cent of the economy, according to the Office of National Statistics. Without access to the single market for services, and without free movement of skilled workers, the financial sector will have a strong incentive to move to the European mainland.

This is Germany’s gain. There is a general consensus that many banks are ready to move if Britain quits the single market, and Frankfurt is an obvious destination.

In an election year, this is welcome news for Merkel. That the British Prime Minister voluntarily gives up the access to the internal market is a boon for the German Chancellor and solves several of her problems. 

May’s acceptance that Britain will not be in the single market shows that no country is able to secure a better deal outside the EU. This will deter other countries from following the UK’s example. 

Moreover, securing a deal that will make Frankfurt the financial centre in Europe will give Merkel a political boost, and will take focus away from other issues such as immigration.

Despite the rise of the far-right Alternative für Deutschland party, the largely proportional electoral system in Germany will all but guarantee that the current coalition government continues after the elections to the Bundestag in September.

Before the referendum in June last year, Brexiteers published a poster with the mildly xenophobic message "Halt ze German advance". By essentially caving in to Merkel’s demands before these have been expressly stated, Mrs May will strengthen Germany at Britain’s expense. 

Perhaps, the German word schadenfreude comes to mind?
