To be estopped or not …

O’Bryan J has ruled that Vehicle Management Systems (VMS) is not estopped from seeking revocation of Orikan’s patent despite earlier opposition proceedings in which VMS could have raised the allegations, but did not.

Under the pre Raising the Bar versions of the Patents Act, it was clearly established that an unsuccessful opponent was not estopped from subsequently seeking revocation on the same grounds. This was at least because of the different onus: an opponent had to show that it was “practically certain” the patent application was invalid to succeed whereas a party seeking revocation only had to satisfy the balance of probabilities standard.[1] The Raising the Bar amendments, however, sought to change the burden at the examination and opposition stages to the balance of probabilities standard. The debate since then has been whether this meant an unsuccessful opponent was estopped from seeking revocation on the same grounds.

Overview

Orikan is the registered owner of Australian Patent No. 2013213708 titled “Vehicle Detection”, having been assigned the patent by SARB Management Group. It has sued VMS for infringement. In addition to denying infringement, VMS has cross-claimed seeking revocation of the Patent. So, this is another campaign between VMS and SARB-related entities over competing systems and apparatus to detect cars which have overstayed parking.

In this particular application, Orikan was seeking to have VMS’ cross-claim stayed on grounds of Anshun estoppel or, alternatively, as an abuse of process.

Some background

Back in happier days, VMS and SARB had explored jointly developing systems for detecting vehicles which were parked without paying the fee or after the alotted time had expired.

Things didn’t work out and, by a decision handed down in 2013, VMS successfully sued SARB for infringement of one of VMS’ patents for vehicle detection systems.

In 2008, however, SARB had applied for its own patent. That application led to two divisional patents: Australian Patent No. 2011101179 (Innovation Patent), which was filed in 2011, and secondly the Patent the subject of these proceedings, which was filed in 2013. As you might suspect, there was considerable overlap between the claims of the Innovation Patent and the Patent.

In 2012, SARB sued VMS for infringement of the Innovation Patent. VMS defended, including a cross-claim for invalidity on grounds including lack of novelty, secret use and lack of sufficiency and best method. This proceeding settled before trial in 2014.

In 2016, VMS opposed the grant of the Patent. That opposition failed in both the Office and the Court.[2] The Opposition Proceeding in the Court involved extensive evidence and 5 days’ trial. According to O’Bryan J, however, it did not involve the grounds of invalidity or particulars that VMS sought to argue in this proceeding.

In addition to challenging the priority date, clarity and sufficiency grounds, VMS sought to revoke the Patent in this proceeding on grounds of lack of novelty, secret use and failure to disclose the best method.

Given this prior history, Orikan contended VMS’ cross-claim should be stayed on grounds of either Anshun estoppel or abuse of process.

Legal tests

The parties were not really in dispute about the principles.

Anshun estoppel

At [26], O’Bryan J explained:

Anshun estoppel operates to preclude the making of a claim, or the raising of an issue of fact or law, in a subsequent proceeding if the claim or issue was so connected with the subject of an earlier proceeding that it would have been unreasonable, in the context of the earlier proceeding, for the claim not to have been made or the issue not to have been raised in that proceeding …. [3]

Thus, at [28] his Honour considered three conditions needed to be satisfied:

(1) the relevant cause of action, defence or issue must be one that could have been raised in the earlier proceeding;

(2) the same or substantially the same facts must arise for consideration in the second as in the first proceeding; and

(3) it must have been unreasonable in all the circumstances for the party not to have raised the issue in the first proceeding – i.e. it is not enough that the issue could have been raised; in all the circumstances it should have been raised.

The third requirement means the test has an element of discretion and evaluation.

The requirement of “unreasonableness” is a “severe test” and not to be made lightly. O’Bryan J noted one situation where unreasonableness was likely to be established is where a judgment or order made in the second proceeding was likely to conflict with a judgment or order in the earlier proceeding. But, the doctrine is not limited only to such situations.

Abuse of process

Abuse of process is not capable of explanation in terms of closed categories. At [38], O’Bryan J noted the principles governing its application are broader and more flexible than those governing estoppels.

In general terms what needs to be shown is that the use of the Court’s procedures would be unjustifiably oppressive to the party or would bring the administration of justice into dispute. At [39], O’Bryan J noted that this brought into play considerations of the overarching purpose of civil litigation as set out in s 37M.

Why O’Bryan J dismissed Orikan’s application

At [71], O’Bryan J accepted that Orikan, as the assignee of the rights in the Innovation Patent and the Patent, could take the benefit of an Anshan estoppel arising from the earlier proceedings. It had not been a party to the earlier proceedings but, as the assignee, was a “privy” of the SARB entity which had been.

It was not in dispute between the parties that VMS could have raised the invalidity issues it now wished to argue in the earlier Opposition Proceeding. The matters VMS now sought to rely on were either known to it or it ought to have been aware of them. In fact, the grounds and particulars had been asserted by VMS in the Innovation Patent Proceeding and, while they were different patents, they were both derived from the same parent and the claims were substantially similar.

Nonetheless, O’Bryan J considered that it was not unreasonable for VMS not to have raised the issues it now sought to agitate in the Opposition Proceeding.[4]

First, at [75] his Honour considered there was not a relevant risk of inconsistent judgments. His Honour accepted that a finding that the Patent was invalid in this proceeding would be inconsistent with the result in the Opposition Proceeding. As the grounds and particulars relied on in this proceeding were different, however, the basis of an invalidity finding in this proceeding would be different to the basis of the findings in the Opposition Proceeding.

Secondly, O’Bryan J considered at [76] there was a fundamental difference between the nature and consequences of an opposition proceeding and a revocation proceeding. The Opposition Proceeding involved an election by VMS to challenge the Patent on limited grounds. In contrast, in this proceeding, VMS was being sued for infringement and so compelled to come to court. Later, at [80] O’Bryan J noted that his conclusion might have been different if VMS had initiated the proceedings rather than being the respondent.

O’Bryan J also noted that the Innovation Patent Proceeding had not proceeded to trial and so the invalidity claims had not been tested in court.

Thirdly, O’Bryan J considered that allowing the invalidity claims to go forward in this proceeding would not result in more costs and delay than would have been the case if the claims had been brought in the Opposition Proceeding.

There was one overlap with the Opposition Proceeding in that one of Orikan’s witnesses, a Mr Del Papa, had been cross-examined about a particular document and both Mr Del Papa and the document were involved in this proceeding. However, the relevance and cross-examination in the Opposition Proceeding was limited to an issue of entitlement, not in issue in this proceeding.

Finally, O’Bryan J did not place “significant weight” on the public interest in the integrity of the Register or the fact the Act specifically provided for pre-grant oppositions.

O’Bryan J dismissed the abuse of process attack for essentially the same reasons.

An observation

Interestingly, while O’Bryan J did have regard to the in rem nature of patents, the public interest in the integrity of the Register and the specific provision in the Act for pre-grant opposition (and the change in onus), his Honour did not give those considerations much weight. His Honour eschewed adopting a general principle and instead applied an approach very heavily based on the particular facts of the case.

For example, it is often said (as is the case) that defeating an opposition is not a guarantee that the patent is valid. That is also true of an unsuccessful revocation proceeding. The fact one person’s revocation proceeding failed does not preclude anyone else seeking to revoke the patent. And there are cases where the second challenger succeeded despite the failure of the first.

In considering the fundamental difference between the nature and consequences of opposition proceedings and infringement/revocation proceedings, O’Bryan J emphasised VMS’s choice to fight the Opposition Proceeding on limited grounds in light of the nature and purpose of opposition proceedings. At [76], his Honour explained:

But the Opposition Proceeding involved an election by VMS to challenge the validity of the Patent. It did so on limited grounds, and did not raise the grounds and particulars of invalidity that had been raised in the earlier Innovation Patent Proceeding. There is no proper basis to criticise that election. …. The election made by VMS confined the scope of the issues in dispute in the Opposition Proceeding and therefore the costs and time required for its determination. That course was consistent with the overarching purpose of civil litigation expressed in s 37M of the Federal Court of Australia Act 1976 (Cth). It was also consistent with the character and purpose of pre-grant opposition proceedings, which are intended to provide a swift, economical means of settling disputes: Genetics Institute at [19]. Although it is desirable to avoid a multiplicity of proceedings and to ensure that parties address, as far as possible, the issues arising between them in a single proceeding, parties ought not to be encouraged to raise each and every possible claim or issue irrespective of the time and cost associated with doing so. Anshun estoppel must operate conformably with the demands of s 37M, as well as the substantive statutory context in which it is said to arise. (Emphasis supplied)

This suggests his Honour’s conclusion might reflect a reaction to Beach J’s heartfelt paragraph 1784. It is also consistent with a number of extra-judicial comments encouraging some effort on the part of parties to simplify proceedings. It does seem a little odd, however, that an opposition proceeding taking up 5 days’ of the Court’s time and a carefully reasoned 274 paragraph judgment might qualify as a swift economical means of resolving the dispute between the parties especially when the consequences lead to a further infringement proceeding with what promises to be an even more involved revocation component.

Winnebago loses half an appeal

The Full Court has partially allowed an appeal from Foster J’s decision to order Knott Investments to stop using the Winnebago trade marks for “campers” or RVs not made by Winnebago. As a result, Knott can continue to use “Winnebago” if it can make it clear it is not associated with the Winnebago company.

Some facts

From about 1959, Winnebago had been making and selling its RVs under that brand name in the USA and eventually other countries including the UK and Canada, but not Australia.

Winnebago logo

In the early 1960s, Binns became aware of the Winnebago name and logo while travelling around the USA. In 1978, Binns and his wife started manufacturing and selling their own RVs in Australia under the name “Winnebago” and using the Winnebago logo. In 1982, they incorporated Knott which then took over running their business.

The Winnebago company discovered what Knott was up to by 1985. However, the Winnebago company did nothing about this until 1992 when the parties entered into a “settlement” agreement. Following this, Knott kept making and selling its own Winnebago brand RVs and registered the Winnebago logo as trade marks. Winnebago itself did nothing further until 2010, when it wished to enter the market in Australia and started proceedings alleging misleading or deceptive conduct, passing off and seeking revocation of Knott’s trade mark registration for Winnebago and the logo.

When do you test whether conduct is misleading or deceptive

The Full Court allowed Knott’s appeal insofar as it related to when Knott’s conduct had to be tested as misleading or deceptive. Foster J held this was in 1982 when Knott was recorded in the Register of Business Names as having commenced running the business, there being no formal documentation of a transfer of the business. The Full Court, however, considered that Knott was plainly the successor in title to the Binns’ business and so the relevant time was 1978, when the Binns started up.

This is important because the Full Court unanimously considered the relevant time to assess whether conduct is misleading or deceptive under s 52 of the TPA (as it was) and s 18 of the ACL (as it now is) is the date when the “infringer’s” conduct started, not some later date.

As it turned out, however, this did not help Knott much as the Full Court considered the evidence clearly established Winnebago had a “spillover” reputation in Australia in 1978 even though it had not traded in Australia at that point.[1] Therefore, Knott (and the Binns’) conduct was likely to mislead or deceive.

Estoppel, laches, acquiescance or delay

The issue that loomed large in the Full Court’s eyes was Winnebago’s delay in bringing proceedings to enforce its rights – 25 years after it first learned of Knott’s activities and 18 years after the “settlement” agreement. Over that period of time, Knott had built up its own substantial reputation in “Winnebago” in vehicles of its own manufacture.[2]

First, the Full Court agreed with Foster J that the “settelment” agreement did not authorise or concede any rights to use “Winnebago” to Knott. Clause 6 provided:

This Agreement does not address, impact upon, or relate in any way, manner or form to the use or ownership of the [Winnebago marks] in Australia or to any rights relating to the [Winnebago marks] based on reputation or use under any statute or at common law in Australia. By entering into this Agreement, Winnebago does not expressly or impliedly acknowledge that Australian Company has any rights of any nature whatsoever to the [Winnebago marks] in Australia. To the extent not expressed in this Agreement, this Agreement shall be without prejudice to the rights of Winnebago and Winnebago expressly reserves all of its legal rights.

Knott argued, however, that the 18 year delay in bringing proceedings meant it was unjust to permit Winnebago to bring proceedings now. Allsop J despatched this argument for six:

First, there was no clear representation, arising either out of the Settlement Agreement or from the conduct. The terms of the agreement, in their context, contained a degree of commercial ambiguity. The terms, however, of cl 6 could leave no doubt in Mr Binns’ mind that any practical confidence in him that Winnebago was not going to sue him was not based on any right conceded by Winnebago. He proceeded at his own risk. The finding by the primary judge at [155] of the reasons (not specifically challenged) that Mr Binns knew there was a risk of having to rebrand his product if Winnebago entered the market is also fatal to the submission. (emphasis supplied)

Allsop CJ and Jagot J rejected Knott’s arguments based on laches, acquiescance and delay both for similar reasons and because Knott had expressly disclaimed them at trial.

Notwithstanding this, the Full Court considered that Foster J’s order that Knott be restrained from using the Winnebago trade marks was unjust. Even though Knott (or, really, Binns) had adopted the Winnebago trade marks to take advantage of the Winnebago company’s reputation and there was evidence that some members of the public had been misled, nonetheless, Knott had over decades built up its own substantial, independent reputation. Instead, therefore, the injunction should only prohibit use which did not appropriately disclaim any trade association with the Winnebago company. At [67], Allsop CJ explained:

This limitation of relief can be seen to reflect not only the balancing of the respective interests of Knott and Winnebago in the reputation developed by Knott’s expenditure, in the context of Winnebago’s extraordinary (and informed) delay, but also the erosion of the reputation of Winnebago ….

and

The evidence reveals sufficient to conclude that at least some of Knott’s reputation in the use of the name and marks was the development of its goodwill and reputation; that not all of the development of its business involved the taking advantage of Winnebago’s reputation in Australia. In normal circumstances, this would not matter; it would be something that the party passing off would have to accept as a consequence of its wrongdoing. Here, however, Winnebago has contributed to this by standing by, informed of the position, for 25 years while Knott expended money and built a business, part at least of which was its own reputation. (emphasis supplied)

The disclaimer or dissassociation had to be clear on the vehicles Knott made in future as well as in its advertising and promotional material.

The third member of the Court, Cowdroy J, did not explicitly reject the laches or acquiescance defence, but agreed in the approach of Allsop CJ saying at [106]:

the Court considers that the granting of relief to completely restrain the appellants from the use of the Winnebago marks to be unreasonable in light of the substantial delay by Winnebago.

Finally, the Full Court upheld Foster J’s order to cancel Knott’s registration of the Winnebago trade marks. Knott had registered these in direct contravention of the terms of the “settlement” agreement.

Some thoughts

In 1992, a representative of the Winnebago company had written to its then Australian lawyers explaining:

… While we are obviously interested in persuading or compelling Mr Binns to cease using the subject marks in Australia, I really do not think that we can justify any additional expense. We are not selling our products there nor do we have any plans to do so. There has in the past been some indication that Mr Binns was experiencing some financial duress and perhaps with any luck he will go broke. In any event, at least for the time being, I think we will just continue to monitor this situation … [3]

No doubt, the sentiments will resonate with everyone advising a foreign brand owner in Australia. The Full Court’s approach may provide a warning. The terms of the “settlement” agreement were sufficiently limited to preserve the Winnebago company’s right to enter the market and object to misrepresentation of association, but failure to enforce its rights promptly has left it encumbered with a competing, independent user of its brand. On the other hand, Knott did not bring matters to a head in negotiating the “settlement” agreement and finds itself constrained. As Allsop CJ said, it ran the risk. How the disclaimer should be effected is unclear, but there are indications in Allsop CJ’s reasons that Knott has been able effectively to dissociate its business from the Winnebago company, while still using the Winnebago trade marks, since 2003.

Will unsuccessful opponents be estopped?

As noted previously, the “Raising the Bar” bill aims to change the standard of proof required for acceptance of a patent application and for successful opposition from the prevailing “practically certain” or “clear” standard to a balance of probabilities.

Currently, an unsuccessful opponent is not estopped from bringing revocation proceedings, largely because of the difference in onus applying at the opposition versus revocation stage: Genetics Institute v Kirin-Amgen at [17] and note Clinique at [13] (trade mark). At [17], the Full Court in Kirin-Amgen said:

17       During the hearing there was some discussion as to the possibility of the owner of a patent the grant of which was unsuccessfully opposed, defending a revocation proceeding instituted by the pre-grant opponent by raising an issue estoppel in respect of the findings of fact of the single judge. In the present case, however, the respondent has conceded that no issue estoppel would apply to the findings of fact of Heerey J in any revocation proceeding instituted by the applicant in respect of the patent. In any event, the difference between the issue determined by his Honour in the pre-grant opposition proceeding, and the issue that would arise for determination in any revocation proceeding instituted by the applicant, is in our view sufficient to preclude the operation of issue estoppel principles in that second proceeding. The overriding issue in the pre-grant opposition proceeding before Heerey J was whether it was practically certain that the patent to be granted on the specification would have been invalid on the ground that the content of the specification was not in accordance with the requirements of s 40 of the Patents Act 1952 (Cth) (Genetics Institute Inc v Kirin-Amgen Inc (No 3) (1998) 156 ALR 30 at 39-41). Even if revocation of the patent was subsequently sought by the applicant on the virtually identical ground of non-compliance with subs 40(2) or subs 40(3) of the current Act (see par 138(3)(f) of the Act), the issue for determination by the judge hearing that revocation application would be whether the patent should be revoked for the specification’s non-compliance with subs 40(2) or subs 40(3). The decision of Heerey J that it was not practically certain that the patent should be so revoked would be inconclusive of this issue. Accordingly, there would be no scope for the operation of an issue estoppel in relation to the decision of Heerey J in any post-grant revocation proceeding instituted by the applicant in respect of the current patent. (emphasis supplied)

What the Full Court said in the emphasised passages was obiter as the point was conceded. Given the reason why the Court accepted the concession, however, it may well be that an unsuccessful opponent will be estopped from from bringing revocation proceedings in those cases where the “practically certain” standard no longer applies.

The absence of discovery and, usually, cross-examination and, possibly, the very nature of opposition proceedings may however lead to a contrary conclusion: see the Court of Appeal’s ruling in Special Effects v L’Oreal (commentary by IPkat and Birds), albeit

(a) involving an opposition in the Registry and not the Court; and

(b) recognising the possibility that the revocation proceedings may be stayed as an abuse of process.

The fact the earlier UK proceeding was in the Registry and did not involve discovery or cross-examination could be a highly important point of distinction as cross-examination and, sometimes, discovery do occur when opposition proceedings are appealed to the Court.

When the change takes effect, prospective opponents would still be very well advised to consider carefully whether to oppose, or keep their powder dry, and, if they do oppose, do it properly right from the start. Of course, even under the current standard, a half-hearted opposition can seriously prejudice the outcome of both the opposition and subsequent revocation proceedings.

The Secret – more forum wars

Late in July, Sundberg J found that Australia was clearly an inappropriate forum to litigate the dispute over ownership and infringement of copyright in the film and the book, The Secret.  Now there is an appeal on foot.

To recap: interests associated with Ms Rhonda Byrne commenced proceedings in Australia claiming to be the owner of copyright in the film of The Secret.  Drew Heriot was the director of the film – there is a dispute between the parties over whether he was employed by one of the Byrne interests or the respondent in this proceeding.  In any event, the Heriot interests brought parallel proceedings in the USA.

Sundberg J considered Australia was clearly an inappropriate forum.  Broadly, this was on the basis that it was necessary to have regard to the whole dispute between the parties, not just the component of the litigation relating to Australia.  On that basis, by far the greater amount of damages at stake were those for infringement in the USA (the book has featured on Oprah, amongst others) and only the US court would have power to amend or correct the US Register of Copyrights.  The judge in the US has apparently reached a similar conclusion.

Now, the question in Australia is who should hear the application for leave to appeal: a single judge or the Full Court.  Heerey J has directed that the matter go before a Full Court and, subject to any directions by the Full Court, be heard concurrently with, or immediately before, the appeal.

His Honour considered that the Byrne interests would suffer substantial prejudice if it turned out that Sundberg J’s decision was wrong:

9 However the US proceeding will deal not only with copyright ownership, but with questions of infringement and damages, issues which do not arise in the Australian proceeding. There will be a significant burden, both financial and otherwise, on the applicant in having to contest that proceeding. Moreover, as Mr Batt for the applicant points out, his client’s Australian proceeding was commenced first, seeking a remedy under Australian legislation arising out of events which allegedly took place in Australia. The opportunity for the applicant to contest, and possibly win, the Australian proceeding, without having to defend the more extensive US proceeding, is something of real value, the loss of which arguably amounts to real injustice, supposing Sundberg J’s decision to be wrong. Apart from anything else, victory in the Australian proceeding may create some issue estoppel in favour of the applicant, or give it leverage in commercial negotiations.

Heerey J did avoid the question of whether the decision was in fact wrong.  It was not the subject of detailed submissions by either party.  In any event, experience taught that the two questions could not often be treated in a vacuum.  Moreover, there was a chance the matter could be dealt with in the November sittings if not before.
