background facts
2 Mr Costin is registered as the patentee of Patent No. 734266 for an invention entitled "Retractable Measuring Tape for Brick Laying" (the patent). In general terms, the patent claims a retractable measuring tape for brick quantity calculation, where the tape is marked at regular intervals corresponding to two or more brick gauges to indicate the required number of bricks for a given distance of brickwork (the patent tape).
3 Mr Costin and his wife, Elaine Costin, operate a business known as KwikGauge Australia. The business name is registered pursuant to the Business Names Registration Act 2011 (Cth). Mrs Costin is recorded as the business name holder.
4 In July and September 2012, inquiries undertaken by, and information provided to, Mr Costin revealed to him that certain suppliers in Australia were offering retractable measuring tapes similar to the patent tape. Mr Costin's inquiries included online searches and the purchase of certain retractable tape products from two suppliers identified as Vetner Pty Ltd and Lyndons Pty Ltd, both of which carry on business at various outlets in Queensland. The relevant retractable measuring tapes supplied by these companies bore brand names that included the word "OX" (OX gauge tape). Mr Costin was informed that a representative of Duroline was offering this product. OGG is the proprietor of a number of registered trade marks that comprise or include the word "OX".
5 Mr Costin's inquiries also revealed to him that Duroline was offering a retractable tape for measuring brick course under a brand which includes the name "Axis" (Axis gauge tape). OGI is the proprietor of the registered trade mark "Axis Building Tools".
6 Having ascertained these details, Mr Costin's solicitors, Neville & Hourn Legal (NHL), wrote a letter of demand addressed to Duroline and OGI. The letter was dated 22 October 2012 and was marked for the attention of Mr Hales. The letter made the following claims:
• "Gauge tape" is advertised and sold through the Duroline website, and is available for purchase at several in-store locations throughout Australia.
• "Brick gauge tape" is advertised and sold through the OGI website (which redirects from the Duroline website), and is available for purchase at several in-store locations throughout Australia.
• The sale and distribution of these products infringe the patent.
7 The letter defined these products as, jointly, "the Infringing Product", although, in places, the letter also referred to "Infringing Products". The letter continued:
Without further notice to you, our client intends to take further action to restrain any further infringement by your company/companies and any related entity which may have supplied the Infringing Product. We are also seeking instructions to commence proceedings against you personally.
8 This last reference was clearly directed to Mr Hales. The letter then demanded that Duroline, OGI and Mr Hales, and their "related entities" take a number of immediate steps "[i]n the interests of potentially reducing the quantum otherwise payable to our client in the form of either damages or as an account of profits". The steps were to:
• remove all advertisements, marketing, brochures, sales and "abilities to purchase" any and all products known as either "gauge tape" or "brick gauge tape" which appear online at (a) www.duroline.com.au/our-catalogue.php; (b) www.ox-cp.com.au/products/; and (c) www.sydneytools.com.au/;
• provide a copy of the receipts pertaining to the sale of any and all products (that is, the "Infringing Product") for the period "1 November 2006 to present";
• provide a list of persons and/or companies who had supplied the Infringing Product within the specified period (whether online or in-store), which outlines their relevant contact details;
• provide an undertaking that Duroline, OGI or "any related entity" would refrain from the supply, manufacture, distribution, sale, advertisement or marketing of any product "for which the Patent provides our client has claim"; and
• provide a list of those persons and/or corporations "who you have sourced for the purposes of manufacturing the Infringing Product, and outline their relevant contact details".
9 The letter concluded by stating:
If we have not heard from you by 5:00pm on Thursday 25 October 2012, we will be making an immediate application to the Federal Court of Australia and will be initially seeking any interim relief we deem necessary to protect our client's legitimate interest in the Patent.
10 The solicitors for Duroline, OGI and Mr Hales - Davies Collison Cave (DCC) - responded, initially on 25 October 2012 and, more fully, on 30 October 2012. In their second letter, DCC stated that each of Duroline, OGI and Mr Hales denied "each and every claim and allegation of wrongdoing" made against them in the letter of 22 October 2012. DCC also stated:
Without prejudice to our clients' respective positions in relation to the claims and demands against them, or in respect of the validity of Australian Innovation Patent No. 734266, which is not admitted, we are instructed to advise that the allegedly "Infringing Product" referred to in your letter is already no longer available for sale by our clients, the last units having been sold on 14 September, 2012. We are further instructed that it will not be offered for sale again in the future.
11 In providing that response, DCC took NHL's letter of 22 October 2012 to be referring to the OX gauge tape. There was some debate on the hearing of the application as to whether DCC, and hence the prospective respondents, were justified in taking that position. NHL's letter referred to gauge tape advertised and sold through the Duroline website, but did not otherwise identify that tape, save to say that NHL were holding receipts "for the purchase of the Duroline and [OGI] Infringing Products". The evidence makes clear that those receipts related to the purchase of OX gauge tape, not Axis gauge tape.
12 NHL responded on the same day (30 October 2012) and enclosed a draft originating application seeking preliminary discovery. In that connection, their letter stated:
We are obtaining our client's instructions to file the enclosed draft originating application.
Please advise whether your client is prepared to consent to the discovery of the categories of documents sought in the schedule to that application, such that unnecessary proceedings may be averted and costs kept to a minimum.
Such a request is to fulfil the objectives prescribed by the Civil Dispute Resolution Act 2011.
If your client is not prepared to consent to discovery of the documents sought, please advise if you hold instructions to accept service on behalf of your client.
13 It appears that this response was prompted because DCC had contended that, in the context of Mr Costin having threatened to commence proceedings against Duroline, OGI and Mr Hales, Mr Costin had failed to take genuine steps to resolve the dispute. A fair reading of NHL's letter of 22 October 2012 leaves no doubt that, at that time, Mr Costin, through NHL, considered that he had sufficient information, and had resolved, to commence proceedings against Duroline, OGI and Mr Hales for infringement of the patent.
14 The draft originating application identified Duroline, OGI and Mr Hales as prospective respondents. It contained orders seeking discovery according to categories of documents. The categories were substantially the same as those identified in the present application, insofar as it relates to preliminary discovery under r 7.23. The categories were not addressed to any particular brand of gauge tape. Counsel for Mr Costin relied on this fact to support a submission that the prospective respondents were not justified in assuming that the preliminary discovery that had been sought was limited to OX gauge tape. Moreover, an image of a webpage apparently taken from Duroline's website on 18 October 2012 shows the Axis gauge tape being offered for sale. It refers to that product as "Made in Australia". The webpage also contains the email address "sales@duroline.com.au" and a link to "Terms and Conditions". A copyright notice on the webpage indicates that it was created in 2012. A copy of the webpage was not enclosed in NHL's letter of 30 October 2012 but Duroline, at least, must have been aware of it at that time.
15 On 7 November 2012, DCC responded. They stated that Duroline, OGI and Mr Hales would not provide the documents requested. Their response also contained a detailed argument to the effect that "[a]ny application for preliminary discovery by your client seeking such documents is bound to fail".
16 Thereafter, NHL and DCC, on behalf of their respective clients, engaged in a debate, by correspondence, as to whether Mr Costin was entitled to preliminary discovery. That debate has continued beyond the commencement of the present application. In the course of that debate, OGI provided a spreadsheet of sales of "gauge tape" and "brick gauge tape" made by it. Mr Hales also made a statutory declaration in which he verified that the spreadsheet is "a true and complete record of all sales made by" OGI of "gauge tape" or "brick gauge tape" designated by the product code OX-P020508. This is a reference to the OX gauge tape. The spreadsheet shows, amongst other things, the number and value of sales of that product. In his declaration, Mr Hales also said that he was "not aware of any other entity with which I am associated or with which I have a connection which has sold or offered for sale [the designated product] in Australia". The evidence indicates that the spreadsheet was provided to NHL in a letter from DCC dated 7 November 2012 and that the statutory declaration was provided to NHL in a letter dated 13 December 2012. Copies of these documents were again supplied by DCC to NHL by letter dated 2 May 2013 (that is, after the filing of the originating application).
17 NHL, on behalf of Mr Costin, made no complaint to DCC that the information contained in the spreadsheet and Mr Hales' statutory declaration was deficient, until NHL sent a letter to DCC dated 10 May 2013 (once again, after the filing of the originating application). In that letter, NHL said that the spreadsheet was deficient because (a) it did not identify in detail "the nature of the sale or distribution of either the 'Gauge Tape' or 'Bricker [sic] Gauge Tape'"; (b) the quantity of the sales did not match the figure for total sales stated at the end of the spreadsheet; (c) the spreadsheet did not identify the persons to whom the gauge tape was sold or delivered; and (d) the spreadsheet did not identify the manufacturer or supplier of the gauge tape.
18 The second of these deficiencies appears to have arisen from the fact that an initial facsimile transmission of the spreadsheet that was sent to NHL did not include one of its pages. Nevertheless, a copy of DCC's letter dated 7 November 2012 containing a complete copy of the spreadsheet was also sent to NHL by post. No complaint is now maintained that the spreadsheet is deficient in this respect.
19 Importantly, however, NHL's letter did not suggest that either the spreadsheet or Mr Hales' statutory declaration was deficient because it did not record sales of the Axis gauge tape, or that sales of gauge tape by Duroline had been omitted and were required. This was so even though Mr Costin's affidavit sworn on 19 April 2013 in support of the present application gave evidence concerning the current offering of Axis gauge tape. Counsel for the prospective respondents relied on that failure to submit that, until the filing and service of Mr Costin's affidavit, the only gauge tape in contention had been the OX gauge tape, not the Axis gauge tape. Indeed, in their written submissions, the prospective respondents relied upon Mr Costin's failure to make "reasonable inquiries" in relation to the Axis gauge tape as a reason why preliminary discovery should be refused in respect of that product.
20 In the course of oral submissions, I raised with counsel for the prospective respondents the fact that, despite the submission that the only gauge tape in contention was the OX gauge tape, and despite the fact that it had been asserted in submissions (without evidence) that sales of the Axis gauge tape had not been made for some years, Mr Costin's affidavit included evidence that, as at 16 April 2013, the Axis gauge tape was being offered for sale via a website apparently associated with a business called "Sydney Tools" operating at five locations in Sydney. I should add at this point that there is no evidence that links the business of Sydney Tools to any of the prospective respondents, beyond the fact that Axis gauge tape is offered and OGI is the registered proprietor of the trade mark "Axis Building Tools".
21 As a result of this exchange, counsel for the prospective respondents sought to reopen their case by filing and reading an affidavit made by Mr Hales, apparently during the luncheon adjournment, in which he annexed a spreadsheet of sales of the Axis gauge tape made by Duroline in the period 6 July 2007 to 10 March 2008. In this affidavit, Mr Hales deposed to the fact that the spreadsheet contained "a true and complete record" of all sales of the Axis gauge tape and that the information for the spreadsheet had been "extracted from the EXO accounting kept by [Duroline] in the course of its business".
22 Counsel for Mr Costin objected to the prospective respondents seeking to reopen their case in this fashion. He relied on the fact that Mr Hales' evidence, in this regard, was inconsistent with the fact that the Axis gauge tape was still being offered for sale and that he was not then in a position to test or challenge that evidence. He informed the Court that, on his instructions, the Axis gauge tape was currently available for sale. I pause to add that this was an allegation that had been made in NHL's letter of demand dated 22 October 2012, although no evidence of such offerings was adduced in support of the application. The evidence, in that regard, was limited to offers of the Axis gauge tape made on the two websites to which I have referred.
23 I allowed the prospective respondents to reopen their case in this fashion. I did so because the state of the evidence supported the real possibility that, until receipt of Mr Costin's affidavit, the prospective respondents were genuinely under the impression - even if as a result of their own mistake - that only the OX gauge tape was in contention. Although the supply of Axis gauge tape should have been addressed previously in the prospective respondents' evidence, I was satisfied that Mr Hales' affidavit was relevant to the issues raised in the present application and was probative. I accept that Mr Costin may not have been in a position to test this evidence as he would have liked. Nevertheless, the existing state of his own evidence showed that, despite Mr Hales' evidence, the Axis gauge tape had been offered by Duroline in 2012 on its website and was currently being offered by another supplier, Sydney Tools. Moreover, although there was no evidence of the fact, Mr Costin was obviously seized of information that enabled NHL to state in their letter of 22 October 2012 that the gauge tape offered on Duroline's website in 2012 was available for sale in stores.
24 In the circumstances, I was not satisfied that any prejudice to Mr Costin was such as to warrant the refusal of the prospective respondents' application to reopen their case by relying on Mr Hales' affidavit. The weight to be attributed to that evidence is a different matter.
25 Counsel for Mr Costin made an application for an adjournment but did not persist with it, citing reasons of cost for that decision.
26 The following additional matters should be noted.
27 First, prior to the filing of the originating application, Duroline, OGI and Mr Hales were identified as prospective respondents in the (then) threatened application for preliminary discovery. OGG was not identified as a prospective respondent. Moreover, no letter of demand was addressed to it. This appears to have been a step that was deliberately taken. On the other hand, Mr Hales is not a prospective respondent in the present application.
28 Secondly, the evidence reveals that, after the filing of the application for preliminary discovery, OGI offered to disclose the name of the supplier of the "gauge tape" that OGI had sold, provided that the application was withdrawn on the basis that the parties bear their own costs.
29 Thirdly, the evidence also discloses the existence of another gauge tape supplied under the brand "Technique Tools". The relevance of this product to the present application was not explained. The evidence consisted of images of the product. The provenance of those images was not elucidated. There is no evidence that links the product in any way to the prospective respondents. I have not given that product any further consideration.
