"i) The court must consider whether the claimant has a 'realistic' as opposed to a 'fanciful' prospect of success: Swain v. Hillman[2001] 2 All ER 91 ; ii) A 'realistic' claim is one that carries some degree of conviction. This means a claim that is more than merely arguable: ED & F Man Liquid Products v Patel[2003] EWCA Civ 472 at [8]; iii) In reaching its conclusion the court must not conduct a 'mini-trial': Swain v. Hillman; iv) This does not mean that the court must take at face value and without analysis everything that a claimant says in his statements before the court. In some cases it may be clear that there is no real substance in factual assertions made, particularly if contradicted by contemporaneous documents: ED & F Man Liquid Products v. Patel at [10]; v) However, in reaching its conclusion the court must take into account not only the evidence actually placed before it on the application for summary judgment, but also the evidence that can reasonably be expected to be available at trial: Royal Brompton Hospital NHS Trust v Hammond (No 5)[2001] EWCA Civ 550 ; vi) Although a case may turn out at trial not to be really complicated, it does not follow that it should be decided without the fuller investigation into the facts at trial than is possible or permissible on summary judgment. Thus the court should hesitate about making a final decision without a trial, even where there is no obvious conflict of fact at the time of the application, where reasonable grounds exist for believing that a fuller investigation into the facts of the case would add to or alter the evidence available to a trial judge and so affect the outcome of the case: Doncaster Pharmaceuticals Group Ltd. v. Bolton Pharmaceutical Co 100 Ltd[2007] FSR 63 ; vii) The court should be especially cautious of striking out a claim in an area of developing jurisprudence, because in such areas decisions on novel points of law should be decided on real rather than assumed facts."
"The court may strike out a statement of case if it appears to the court - (a) that the statement of case discloses no reasonable grounds for bringing or defending the claim; (b) that the statement of case is an abuse of the court's process or is otherwise likely to obstruct the just disposal of the proceedings; …"
"6. The Claimant's works were the first to suggest that contestants at home and in the studio might use their telephones and/or other interactitivy to build cumulative scores to win a prize in a live television quiz. 7. The alleged infringing format co-produced and transmitted by the BBC, 'Come and have a go if you think you're smart enough!' (hereafter 'CHG') was described by the co-executive producer, Miram Segal of Tailor-Made Films Ltd, as 'a fully interactive live quiz event which responds to the viewers' frustrations at being unable to take part. It allows them for the first time the chance to play the same game at the same time for the same big cash prize' (source, C21media.net,19 March 2004 )."
"122. In particular, in cases in which the issue of copying has to be decided on disputed evidence the court should be guided by the sound legal principle that proof of similarity between the alleged infringing work and the original copyright work, coupled with proof of direct or indirect access to the original, is prima facie evidence of copying for the defendant to answer: Francis Day & Hunter Ltd. v. Bron[1963] Ch 587 at 612 per Wilberforce J (a wise judgment, which does not seem to have been cited to the judge). 123. The application of this principle and some reference to the applicable provisions of the 1988 Act (none of which feature in the judgment) would, I think, have disciplined the reasoning and strengthened the structure of the judgment. 124. The following issues frequently arise for decision in proceedings for infringement of literary copyright under the 1988 Act. Although this is not an exhaustive checklist, the following are worth bearing in mind as issues that will usually need to be considered, preferably in a chronological setting or, in more complicated cases, of sub-sets of chronologies. (1) What are the similarities between the alleged infringing work and the original copyright work? Unless similarities exist, there is no arguable case of copying and an allegation of infringement should never get as far as legal proceedings, let alone a trial. The 1988 Act confers on the owner the exclusive right 'to copy the work' either direct or indirectly (section 16). This is not an exclusive right to prevent the publication of a work on a similar subject or a work which happens to contain similar material, thematic or otherwise. (2) What access, direct or indirect, did the author of the alleged infringing work have to the original copyright work? Unless there was some evidence from which access can be directly proved or properly inferred, it will not be possible to establish a causal connection between the two works, which is essential if the Claimants are to prove that the Defendant's work is a copy. ... (6) What are the circumstances or factors which justify evaluating the part copied in the alleged infringing work as 'a substantial part' of the original copyright work?"
"143. The decision on the substantiality or otherwise of the copying of HBHG in DVC required a careful assessment or evaluation of all the relevant evidence by the fact-finding tribunal in the context of the pleaded case. This included the nature and extent of the copying, having regard to the importance, as well as the amount, of what has been copied from the original work, and the nature of the respective works. 144. The 1988 Act does not define 'a substantial part' or even indicate what factors are relevant to substantiality. I do not think that there is any real point in asking: what does 'a substantial part' mean? That sort of question is only a path to a dictionary and to the dubious substitution or addition of other words which do not help to answer the crucial question of fact: is DVC a copy of 'a substantial part' of HBHG? 145. It is more sensible to ask whether there exist in this case the necessary and sufficient conditions for characterising the parts copied from the original work as 'a substantial part' of the original work. The decided cases help in identifying the relevant necessary and sufficient conditions for substantiality. Thus, it is not necessary for the actual language of the copyright work to be copied or even for similar words to be used tracking, like a translation, the language of the copyright work. It is sufficient to establish that there has been substantial copying of the original collection, selection, arrangement, and structure of literary material, even of material that is not in itself the subject of copyright. 146. It is not, however, sufficient for the alleged infringing work simply to replicate or use items of information, facts, ideas, theories, arguments, themes and so on derived from the original copyright work. 147. I agree with Lloyd LJ that no clear principle can be laid down on how or where to draw the line between the legitimate use of the ideas expressed and the unlawful copying of their expression."
