1. 2013 IP Scholars Roundtable Drake University, April 12-13, 2013 Trademark Law and the Public Domain Prof. Martin Senftleben VU University Amsterdam Bird & Bird, The Hague

2. Background

3. ‘Consider the preservation of the public domain within WIPO’s normative processes and deepen the analysis of the implications and benefits of a rich and accessible public domain.’ (Adopted Recommendation 16) ‘To promote norm-setting activities related to IP that support a robust public domain in WIPO’s Member States...’ (Adopted Recommendation 20) WIPO Development Agenda

4. identification distinctive character protection against confusion communication reputation/ repute protection against dilution exclusive link with a sign creation of a brand image advertising quality control Need for preservation measures

5. new meanings, new connotations (enrichment) monopolization, redefinition (impoverishment) Impact on communication resources

6. TM ownercompetitor consumers social, political, cultural speech commercial speech Stakeholders

7. Hypothesis 1: Broad Approach Needed

8. not only signs unencumbered by trademark rights but also free use of protected signs (including exceptions) Notion of the public domain

9. Hypothesis 2: More Exclusions Needed

10. signs excluded from protection inherently distinctive signs acquisition of distinctiveness through use outright exclusion of certain kinds of signs acceptance only on certain conditions Available preservation tools

11. Advertising slogans

12. ‘It is clear, however, […] that those marks are not, by virtue of that fact alone, devoid of distinctive character.’ (para. 56) ‘…in particular, where those marks are not merely an ordinary advertising message, but possess a certain originality or resonance, requiring at least some interpretation by the relevant public, or setting off a cognitive process in the minds of that public.’ (para. 57) CJEU, 21 January 2010, case C-398/08 P, Audi/OHIM

13. New kinds of signs

14. ‘Consumers are not in the habit of making assumptions about the origin of goods based on their colour or the colour of their packaging, in the absence of any graphic or word element, because as a rule a colour per se is not, in current commercial practice, used as a means of identification. A colour per se is not normally inherently capable of distinguishing the goods of a particular undertaking.’ (para. 65) CJEU, 6 May 2003, case C-104/01, Libertel

15. Signs of cultural significance

16. CJEU, C-283/01, Shield Mark/Kist ‘I find it more difficult to accept […] that a creation of the mind, which forms part of the universal cultural heritage, should be appropriated indefinitely by a person to be used on the market in order to distinguish the goods he produces or the services he provides with an exclusivity which not even its author's estate enjoys.’ (Opinion A-G Colomer, 3 April 2003, para. 52)

17. investment in abstract colour marks desirable? investment in cultural heritage marks desirable? important policy decisions left to market participants? Too much reliance on distinctive character?

18. Outright exclusion

19. ‘In the present case, it has not been disputed that the shape of the Lego brick has become distinctive in consequence of the use which has been made of it and is therefore a sign capable of distinguishing the appellant’s goods from others which have another origin.’ (para. 40) nonetheless qualified as functional risk of consumer confusion accepted CJEU, 14 September 2010, case C-48/09 P, Lego/OHIM (Mega Brands)

20. Hypothesis 3: More Exceptions Needed

21. use in trade/ as a trademark limitation of trademark rights specific infringement criteria: likelihood of confusion/dilution use in trade/use as a trademark specific infringement criteria adoption of statutory exceptions Available preservation tools

22. O2: –registered bubbles as a trademark Hutchison: –shows in advertising for telecom services black- and-white pictures of moving bubbles –compares prices of telecom services –not perceived as a source identifier by the public CJEU, June 12, 2008, case C-533/06, O2/Hutchison

23. referential use actionable creation of a further exception ‘...that the proprietor of a registered trade mark is not entitled to prevent the use, by a third party, of a sign identical with, or similar to, his mark, in a comparative advertisement which satisfies all the conditions, laid down in Article 3a(1) of Directive 84/450 [= Article 4 Directive 2006/114/EG], under which comparative advertising is permitted.’ (para. 45) CJEU, June 12, 2008, case C-533/06, O2/Hutchison

24. ‘It is calm above the tree tops/ somewhere a cow is bellowing/ Moo!’ referential use actionable recognition of ‘due cause’ defence for safeguarding freedom of speech German Supreme Court, 3 February 2005, case I ZR 159/02, ‘Lila Postkarte’
