Trade Marks and Passing Off

Fiona is a very experienced trade mark practitioner and has been an author of Atkins Court Forms “Trade Marks” volume since 2001. She is also an Associate Member of the Institute of Trade Mark Attorneys. A list of some of Fiona’s more recent reported trade mark cases is set out below. However, she also has considerable experience in the preparation of evidence and submissions for use in proceedings before OHIM and in appeals from OHIM decisions, although in many instances her involvement does not become public, such documents being filed by her instructing solicitors or trade mark attorneys. Her clients range from multinational pharmaceutical corporations, national trade associations and high street and internet retailers to premier league football clubs, fashion designers, restaurants and artisan food producers. She also has considerable experience of licensing and franchising disputes. Many of these, although essentially contract cases, involve complicated points of trade mark law.

Recent reported cases include:

Sofaworkshop Ltd v Sofa Works Ltd [2015] ETMR 37, [2016] F.S.R. 3

Acting for the defendant in proceedings for CTM infringement and passing off conducted in the IPEC and raising issues as to the extent of use necessary to maintain a CTM, the registrability of descriptive names, acquired distinctive character, assessment of likelihood of confusion (particularly where arising through the use of internet searches) and the handling of what was effectively survey evidence. The claimant failed on all technical points of trade mark law but was ultimately successful in passing off.

C-294/12 and T-369/10 You-Q BV v OHIM (EU:C:2013:300 and EU:T:2012:177)

Appeal to the General Court in opposition proceedings relating to an application to register BEATLE for goods including wheelchairs based on the earlier mark THE BEATLES under art. 8(5). The issues raised included challenges to the nature and extent of the reputation relied upon, the degree of similarity between the marks, the overall likelihood that a “link” would be established and whether unfair advantage had been properly established. Decision of the Board of Appeal that the opposition had been well founded was upheld. Further appeal to the CJEU failed..

Case C-106/11P Helena Rubinstein SNC v. Allergan Inc [2012] ETMR 40

Appeal to the CJEU in cancellation proceedings relating to the Community trade marks BOTOLIST and BOTOCYL based upon the earlier mark BOTOX under art. 8(5). The issues raised included proof of reputation, the establishment of the necessary “link”, the establishment of detriment, the CJEU on appeal from the General Court, the admissibility of documents which had not been translated and the nature of the requirement that the General Court give reasons for its decisions. Decision of the General Court cancelling both registrations upheld.

Plentyoffish Media Inc v. Plenty More LLP [2012] RPC 5

Appeal to the High Court in invalidation proceedings under s 47 of the Trade Marks Act 1994. The Opponent asserted goodwill based upon visitors to a website situation abroad.

Georgio Armani SpA v Sunrich Clothing Ltd [2011] ETMR 13, [2011] RPC 15

Appeal to the High Court against a decision in opposition proceedings under section 5(2) of the Trade Marks Act 1994 in respect of an application to register the two letter mark AX in relation to clothing.

Cowshed Products Ltd v Island Origins Ltd [2010] EWHC 3357

Arguments raised included whether the letters OTO indicated a particular religion or belief system. The opposition had succeeded but was successfully overturned on appeal. The appeal raised issues both as to the identity and attributes of the average consumer and as to the extent to which a registrable mark must serve to indicate the goods and services of the applicant and none other as at the date of the application for registration.

Appeal to the High Court in opposition proceedings under sections 5(2) and 5(4) of the Trade Marks Act 1994 in respect of an application to register DIGIPOS and device. The Opponent was the registered proprietor of DIGI and device in respect of goods which clearly overlapped with the specification sought. The Applicant (who had failed below) contended, inter alia, that the DIGI element of the Opponent’s mark was common and had been given too much weight by the hearing officer below. Appeal dismissed and decision of the hearing officer upheld – no sufficient basis for interfering with the decision below.

Kitfix v Great Gizmos [2008] EWHC 2723

Comparative Advertising

Fiona has advised in numerous cases where a trade mark (registered or unregistered) has been used by competitors in comparative advertising, most of which have ultimately been the subject of settlement short of trial. In some instances proceedings have been commenced for infringement of registered trade mark and in others, for malicious falsehood. In particular, Fiona (together with James Price Q.C.) represented Argos in two sets of proceedings against DSG Retail (Currys) in relation to comparative advertisements on the internet for televisions which featured price comparisons in 2008. The action settled a matter of days before the trial was due to be heard. Fiona had earlier acted (together with Andrew Caldecott Q.C.) for DSG Retail in its own comparative advertising dispute with Comet. The interim injunction application in this case is reported as DSG Retail (trading as Currys) v. Comet [2002] FSR 38.

Parallel Imports

Fiona has also been instructed in many cases concerning both counterfeit and grey market goods and has acted for both claimants and for defendants. The products involved have included pharmaceuticals, drinks products, leisurewear, play station controllers and computer software and peripherals. Such cases often involve applications for interim injunctive relief, including disclosure to enable the source of the counterfeit or grey market goods to be identified. Fiona has also acted for brand owners whose goods have been seized by customs officers and where applications have had to be made to the Court to ensure that those goods are not released to the consignee pending trial.
