54 It is apparent from these extrinsic materials that s 100(3)(c) was not intended by the Parliament to provide a defence to an attack on a registered trade mark for non-use on any grounds, including grounds entirely personal to the trade mark owner that do not bear any trading character, so long only as they do not arise from the voluntary actions of the owner.
55 In my opinion, circumstances within s 100(3)(c) will only exist when events arise that are capable of disrupting trade in the area of commercial activity in which goods bearing the registered owner's mark are traded. For the statutory excuse to be made out, those circumstances must cause (in a practical business sense) non-use of the particular mark by the owner, whether or not they have an impact on any persons other than the owner of that mark who are also involved in that same area of commercial activity. There must be a causal link shown between the relevant circumstances and the mark's non-use. This requirement arises from the fact that s 100(3)(c) creates an excuse only where the mark has not been used by the registered owner "because of" circumstances etc. It will not assist the opponent to removal to show the existence of an impediment to use of the kind referred to in s 100(3)(c) if he does not also establish that, but for that impediment, he would have used the mark. Cf In re James Crean & Son Ld's Trade Mark at 162.
56 Circumstances that do not have a trade character but which only affect a mark owner in his personal character, such as illness afflicting the owner of the mark that is sufficiently disabling to prevent the owner using the mark, can never therefore found an answer within s 100(3)(c) to an application for removal of the mark for non-use.
57 I mention that s 46(1)(a) the Trade Marks Act 1994 (UK) now permits revocation of a trade mark on the ground that "within the period of five years following the date of completion of the registration procedure it has not been put to genuine use in the United Kingdom, by the proprietor … in relation to the goods or services for which it is registered, and there are no proper reasons for non-use". This Act was introduced in order to implement the first Trade Marks Directive of the Council of the European Communities; the reason why the expression "proper reasons" appears in s 46 is not because the draftsman decided that the expression "special circumstances in the trade" in s 26 of the 1938 UK Act should be replaced by a different one, but because he was required to implement the EC Directive. See Magic Ball Trade Mark (1999) 117 RPC 439 at 441 and 442. Decisions in which this provision has been considered are collected in Kerly's Law of Trade Marks and Trade Names, 13th ed, 2001, at par 9-62. They are, however, of little assistance in seeking the meaning of s 100(3)(c) because of the different genesis of the UK legislation and the different wording of that provision.
58 There is also a question whether circumstances that constitute an obstacle to use of the mark must exist throughout the whole of the three year period if they are to be sufficient for the purposes of s 100(3)(c) or whether it is enough that they exist during a part (no doubt, during more than a de minimis part), of that period. The latter view is, in my opinion, the better reading. For the reasons given, a single bona fide use of the mark during the relevant three year period is, by force of s 100(3)(a), an answer to an application for removal for non-use. An obstacle of the kind referred to in s 100(3)(c) to the use of the mark that operates only for part (ie, more than a de minimis part) of the three year period provides the same justification for non-cancellation as does a single user of the mark in the relevant three year period, but only provided the opponent to removal establishes that the mark would have been used during that part of the three year period but for the existence then of the obstacle. A use of the mark which it is shown would have occurred during part of the three year period, but for the existence of the obstacle during that part of the period, has, in my opinion, the same claim to be recognised as excusing non-use that an actual use during that particular part of the period has.
59 But even if the evidence were sufficient to establish that for some time more than a de minimis period in the three years 17 August 1995 to 17 August 1998 Mr Burmingham was seriously ill and that, but for his illness, he would have ensured that the first applicant used its mark during the period of his disability that, for the reasons given, is incapable of providing the first applicant with an answer, pursuant to s 100(3)(c), to the respondent's allegation of non-use of the first applicant's mark throughout that three year period.
60 The appeal must be dismissed.
