Background to the design, assembly and marketing of the Rabbit corkscrew by Metrokane 1 This litigation has its origins in a corkscrew product called Rabbit, the development whereof was initiated in the United States of America, in or about September 1997 by the Respondent/Cross-Claimant Metrokane Inc ('Metrokane'), a company established in 1983 in the United States. Metrokane conducts the business of designing and selling unique houseware products. The marketing director and one of two substantial shareholders of Metrokane has been at all material times Robert Larimer ('Mr Larimer'), who gave evidence in the proceedings by affidavit and by video link from New York. 2 In about October 1997, Metrokane engaged Edward Kilduff, ('Mr Kilduff') being the second cross-claimant and a citizen of the United States, and then associated informally with Daniel Winigrad ('Mr Winigrad') under the business name Link Product Design and Development of New York, to develop a new design for a corkscrew having a lever-action. His instructions were to produce a design which would be refined and elegant yet be 'utilitarian and homely'. It was also to have award winning aesthetics, with a distinctive design and an aesthetically visual appeal, rather than something merely utilitarian and functional. Mr Kilduff is, and was at all material times, an industrial designer, as also apparently was Mr Winigrad. Their business relationship was not formalised by documentation. The mechanism of the corkscrew was to be based upon the technical principles of a patent for lever action corkscrews, owned by the multinational manufacturer Le Creuset, which was due to expire in July 1999. The trade name of the Le Creuset corkscrew was and apparently still is Screwpull. Mr Larimer informed Mr Kilduff that he expected that a number of lever-action corkscrews would be produced and arrive on the market after the expiry of that patent. 3 Mr Kilduff initially produced to Metrokane for approval a two-dimensional drawing, referred to in the evidence as the Kilduff drawings. The Kilduff drawings are Exhibit 'R3' in the proceedings. Mr Kilduff explained that he incorporated into the design certain elements intrinsic to the Screwpull product, including a lever handle and two gripping handles. Those elements were said by Mr Kilduff to be necessary to the operation of an effective lever-action corkscrew. He then drew the shape of the housing for the elements of the mechanism, which were not to be visible in the contoured body designed to cover and obscure the mechanical elements. Mr Kilduff also drew contoured curves 'as aesthetically pleasing as possible', with the resemblance of a rabbit head. Mr Kilduff determined that the coating of the plastic components be that of 'an easy-to-grip rubberised finish of Japanese manufacture', comprising 'transparent spray-on material with the ability to actually "texturise" a smooth plastic surface', said by him to contribute to the ultimate rabbit-like appearance of the product by giving it a 'furry' look and feel. He asserted that such 'finish' on the body and three handles tended to 'unite the parts into one aesthetic whole'. 4 The drawings when completed were submitted to Metrokane for approval, and Mr Kilduff was thereafter instructed by Mr Larimer to move to the next phase of his retainer, namely the transformation to a three dimensional model of the completed two-dimensional drawing. That transformation was completed in December 1997, and comprised the first prototype of the Rabbit corkscrew, being identified in the proceedings as the Renshape prototype. A photograph or photocopy thereof is Exhibit 'R4' in the proceedings. It could not apparently be any longer located in the factory in China and therefore could not be tendered in evidence. In the course of that transforation, he added two distinctive features to the lever-action handle, being grip pads on the top and bottom of the handle, and the encasement of a magnifying lens on the top of the corkscrew. The Renshape prototype was a rough semi-working model and took two to three weeks to construct. It was made out of material called Renshape, which is similar to compressed foam, by using an exacto blade (or razor blade), a dremel (a mechanical piece of sandpaper that oscillates), and bondo (an auto body filler used to correct mistakes). It had a lever action style and an internal mechanism adapted by Metrokane from the Screwpull corkscrew. To cite Mr Kilduff's oral evidence, '[i]t was pretty much an exact use of that mechanism'. It could move but was not functional as a corkscrew. Mr Kilduff said that the moulding of the Renshape prototype '… wasn't an easy process, a lot of trial and error… but I had the guts of the Screwpull mechanism and I would attach the Renshape compressed foam material encompassing the mechanism and a combination of those two materials and the bonds and myself sculpting away…'. 5 Mr Kilduff next prepared design control drawings to enable Metrokane's manufacturing factory in China to build the product and 'to figure out how to inject mould in all three pieces and make all these pieces snap fit'. The dimensions of the prototype were measured with electronic callipers to ensure the dimensions in the design control drawings would be the same size as the prototype. Mr Kilduff entered the data into a computer program called 'Ashlar Vellum'. The Renshape prototype was not tendered into evidence. 6 After the design control drawings and the prototype had been sent to the factory in China, they were redrawn in a three dimensional wire-frame shape, using thereby an AutoCAD computer program. That shape did not undergo subsequent alteration, at any rate, to any significant extent. After the wire-frame drawing was completed, the factory hooked it up to a milling machine and made another prototype of the shape; this was referred in the evidence as the 'CNC Model'. That was done before the factory began cutting the moulds for the tools of the product. The CNC Model was then sent to Mr Kilduff in the United States for approval. The CNC Model was also not tendered into evidence. 7 Mr Kilduff thereafter instructed the Metrokane factory in China to make the Rabbit corkscrew black in colour by using black plastic, and to apply a rubber coating called Whale. He said that he oversaw the design and assembly in the factory in China, in order '… to make sure it is what I had in mind'. Although the Rabbit corkscrew is a so-called 'functional or utilitarian article', Metrokane's case was that the same had nevertheless 'real aesthetic qualities', being described by Metrokane as having the following artistic features: '(i) contoured body, which resembles the head of a rabbit presenting a "bunny profile" - the lever handle being the profile of a rabbit's ears, the body being the rabbit's head and the end of the lever axel serving as the rabbit's eye; (ii) rubberised finish supporting the rabbit analogy with a "fury" texture; (iii) rubberised finish applied to the three handles as well as the body uniting the four parts into a single aesthetic whole; (iv) soft grip pads (of neoprene) inserted in the top and bottom of the lever handle to facilitate a good grip in use; and (v) Metrokane logo.' Mr Kilduff said in evidence that '… most of the aesthetics were followed off my original design, I would say all of them'.
