Scope of disclosure in an innovation patent

Leave a Comment / Patents / / / , , , , , ,

Patentology has a nice summary of the innovation patentee’s successful appeal in Seafood Innovations Pty Ltd v Richard Bass Pty Ltd [2011] FCAFC 83.

One point: it seems like the disclosure in the body of the specification supporting the broadest claim was at a level of generality similar to that upheld by the High Court in the first round of Lockwood. Wonder how that will hold up for future application under the (proposed) Raising the Bar legislation?

Secondly, the (now) infringer’s best line of defence (apart from invalidity) seems to have turned on trying to argue (now unsuccessfully) that incorporating additional integers in the accused gutting machine to those specified in the claim. Bennett J gave it short shrift.

Raising the bar – some differences between the Exposure draft and the Bill

Leave a Comment / Patents / / / , , , , ,

As noted previously, the Intellectual Property Laws (Raising the Bar) Amendments Bill was introduced earlier this week, following fairly extensive consultations on an exposure draft of the Bill.

Patentology has now looked at some of the differences in the proposed changes to the Patents Act between the exposure draft and the Bill as introduced here. His earlier post looked at the different transitional regime for the new standards for patentability.

Will unsuccessful opponents be estopped?

Leave a Comment / Patents / / / , , , , , ,

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 Raising the Bar Bill

3 Comments / Copyright, Designs, Enforcement, IP generally, Patents, Trade marks / / / , , , , , , , , , , ,

Senator Carr introduced the Intellectual Property Laws (Raising the Bar) Bill 2011 into Parliament today.

Press release

Download the text of the Bill and EM from here (choose your own format).

You will remember that (according to the Press Release) the main objects of the Bill include:

  • raising patent standards to ensure Australian innovators are well placed to take their inventions to the world;
  • increasing penalties for trade mark counterfeiters;
  • improvements to border security measures for goods that infringe copyright and trade marks;
  • providing free access to patented inventions for researchers; and
  • cutting red tape and delays when seeking an IP right.

While there have no doubt been modifications to the text of the Exposure Draft (and Patentology flags a big change to the transitional provisions for the new patentability standards), you can get a very good feel for what the various parts of the Bill are trying to achieve:

in relation to patents from Dr Summerfield’s 8 part series over at Patentology:

  1. Part 1: inventive standard
  2. Part 2: usefulness
  3. Part 3: provisional specifications
  4. Part 4: enablement
  5. Part 5: claims supported by description
  6. Part 6: experimental use
  7. Part 7: miscellanea including standard of proof
  8. Part 8: transitional

Kim Weatherall also commented on a number of aspects, exploring in particular the (proposed) trade mark criminal offences.

You do need to bear in mind that these commentaries were on the text of the Exposure Draft and it was intended that anomalies identified through the Exposure Draft would be corrected in the Bill so, as I have already noted, there will be changes. Nonetheless, these comments should give you a good fell for what was being intended and issues that might be thrown up.

As you will see from the commentaries on the exposure draft, there are a host of issues to be considered. Time doesn’t permit anything but a cursory attempt on a couple of points here:

Item 113 of Sch 6 will replace the current s 41 of the Trade Marks Act (requiring a trade mark to be capable of distinguishing) with a new provision intended to reverse Blount and ensure that there is a presumption that a trade mark is registrable. It does this by requiring the Registrar to be satisfied that the trade mark is not capable of distinguishing before the Registrar can reject the application on this ground.

So clause 41(2) says “A trade mark is taken not to be capable of distinguishing … only if ….”

(Now I look at it, I wonder how long before it will be before someone tries to argue that “taken not to be capable of distinguishing” means something different to (and less than) “is not capable of distinguishing”. Oh well. Surely that one would be dispatched over the fence for six?)

While the Bill does seek to change the standard of proof against patent applications and patent oppositions from the existing “practically certain to fail” or “clear” type standard to the usual “balance of probabilities (see e.g. items 14 and 15 of Sch 1), no such amendment is proposed for trade mark oppositions. Therefore, the current state of uncertainty on this issue will continue (contrast e.g. Hills v Bitek at [43] – [55] to Sports Warehouse v Fry at [26] – [40]) , even though the school of thought favouring the “practically certain” or “clear” standard was imported from the Patents Act.

The bill will also introduce a whole new regime of oppositions to the registration of trade marks.

Item 18 of Sch. 3 will replace s 52 so that there is an obligation to file a Notice of Opposition which the Registrar, not the opponent, will serve on the applicant. Item 19 will introduce a new s 52A. This will require an applicant to file a notice of intention to defend or the application will lapse.

According to the EM, the regulations (when they are promulgated) will include power for the Notice of Opposition to specify the particulars of the grounds of opposition. The EM explains:

Opponents are currently required to state the grounds on which they intend opposing an application when they file their notice of opposition. However, they are not required to set out the particulars of those grounds. Frequently, this means that the opponent sets out all possible grounds, whether or not they have any intention of relying on them. As a result, the trade mark applicant may be faced with a number of grounds to deal with and no indication of which are key to the opposition until late in the opposition proceedings and sometimes not until the hearing

makes it difficult for the applicant to prepare their case. It also increases costs as the applicant is obliged to prepare a case in response to all grounds raised in the statement of grounds, including those on which the opponent may no longer rely.

The amendment addresses this problem by allowing for regulations to be made to require the opponent to file a statement of particulars of the grounds on which they intend to oppose. This will help focus oppositions earlier, reducing costs and unnecessary effort for the applicant.

The EM talks of the regulations conferring a power to require particulars. Whether this will be a discretionary power to be exercised on a case by case basis or an obligation on all opponents will need to await the terms of the regulations themselves. For example, the EM on items 24 and 25 states that opponents will be required to file both statements of grounds and particulars and  the last paragraph of the EM on item 17 states that the particulars will be required to be filed within 1 month of the filing of the Notice of Opposition.

The regulations will also apparently include a power to amend the statement(s) of grounds and particulars. However, the EM on items 24 and 25 states:

The regulations will only permit the opponent to amend the statement of grounds and particulars under tightly controlled circumstances.

The Federal Magistrates Court will get original jurisdiction in matters under the Designs Act and the Trade Marks Act alongside its existing original jurisdiction in copyright and (what used to be called) trade practices matters.

A problem of expert evidence

1 Comment / Patents / / / , , , , , , ,

VIP Plastics has successfully sued BMW Plastics for infringing its patent for a “Variable-length Dip Tube for a Fluid Transfer Container”. The most interesting point to emerge is why the expert evidence on one side prevailed and, on the other, failed – even so far as being rejected as inadmissible.

How the battle was won

As is typically the case, much of the battle turned on whether applicant’s expert evidence or the respondent’s was accepted. Kenny J denied that the respondent’s expert’s evidence was not admissible and, even if it were, would have preferred the applicant’s witnesses. The applicant’s witnesses were the named inventor and his assistant.

In construing a patent (whether for deciding its validity or if it has been infringed), it has to be read through the eyes of the (non-inventive) person skilled in the art.

Who is the person skilled in the art

Kenny J found at [20] that the relevant field or art in this case was:

the manufacture and use of dip tubes, particularly in chemical transfer drums or like containers used in the agricultural and veterinary fields.

The named inventor gave evidence about the attributes of the person skilled in this art at [21]:

these attributes included a good working understanding of the processing of plastics and the manufacture of plastic products (involving, amongst other things, an understanding of varying grades and types of plastics and manufacturing processes such as extrusion and blow, injection and vacuum moulding, as well as the economies of such processes). According to Mr Mandile, it was also necessary to have some experience and understanding of the manufacture of large plastic fluid containers (of a size more than 20 litres in volume) incorporating some sort of extraction system. Further, it was necessary to have an understanding (of the kind that a chemical engineer would have) of the environmental stress effects on plastics and the performance characteristics of varying grades of polymers under stress and when interacting with the types of chemicals solutions used in agriculture and likely to be stored in the drums. Finally, it was necessary to have some familiarity with the various products and solutions that had been tried in the industry. In Mr Mandile’s opinion, knowledge of this kind was generally confined to people working in the plastics industry, who had experience in the design and processing of plastic containers of larger sizes and the manufacture of plastic packaging and transfer of chemical fluid to and from such packaging. In cross-examination, Mr Mandile stated that he regarded himself as a person skilled in working in the field of dip tubes for agricultural and horticultural purposes.

Kenny J noted that Aickin J had accepted that evidence about the experiments undertaken by an inventor leading up to the invention could be relevant even if “not always likely to be helpful”. As a result, Kenny J considered at [22] that the inventor could also give evidence about the characteristics of a the person skilled in the relevant art, albeit such evidence needed to be assessed carefully. On the other hand, the respondent contended that “just about any engineer with a basic knowledge of manufacturing techniques and a basic knowledge of mechanics of devices could be classified as a skilled addressee”. Kenny J rejected this on the evidence.

Accordingly, her Honour accepted at [23] that:

the skilled addressee is a person with practical knowledge of and experience in the manufacture of plastic products, particularly large fluid containers incorporating some kind of extraction system. That is, such a person would have practical knowledge and experience in the manufacture of plastic packaging for the storage of fluid and the transfer of such fluid from the packaging. Such a person would also have an understanding of the environmental stress effects on plastics.

Why the professor was not a psa

There were a number of problems why Kenny J considered that the evidence of the professor advanced by the respondent was not relevant (and so not admissible). The chief reason was that he had no relevant or special expertise and was unable to give evidence about what those in the art would know or do.

Section 76 of the Evidence Act generally rules opinion evidence inadmissible. One important exception is provided by s 79 for “expert” opinion (about a relevant issue). The opinion is “expert” for this exception where it is evidence from a person if the person “has specialised knowledge based on the person’s training, study or experience” and the opinion “is wholly or substantially based on that knowledge” (emphasis supplied).

In this case (and will not necessarily be true in every case), the professor had worked in the wool industry “for 10 years in the 1980s” and, since then, he had “mainly been an academic, teaching in the area and consulting in minor ways for engineering” when the priority date for the patent was in 2000. Then at [60]:

Of course, in a case such as this, a court may receive expert evidence from persons other than skilled addressees if it is otherwise relevant. There was, however, a serious difficulty with [the professor’s] evidence in another respect: it was not just that he was not a skilled addressee but that he had no history of working in the fields of dip tubes or plastics, or some related field. Without this specialised knowledge, based on training, study or experience, [the professor] was not in a position to give relevant evidence to the court bearing on the meaning of the VIP Patent or a prior publication, the issue of novelty and the issue of obviousness:

Then, so far as the professor gave evidence about the innovation process based on his specialised knowledge, it was not knowledge relevant to the art in question.

There were other problems too: opinions were expressed about questions of mixed fact and law – e.g. it was obvious – based on misunderstanding of key legal concepts; there was also a problem of hindsight.

The use of relative terms

The infringer’s attack on the patent as lacking clarity because it used relative terms such as “inhibits bending” and “just below the end” were dismissed. Kenny J accepted that they were not precise, but found they applied Nesbit Evans Group Australia Pty Ltd v Impro Ltd (1997) 39 IPR 56 at 95 to find they provided a workable standard.

Microsoft v i4i – US Supreme Court decides

1 Comment / Patents / / / , , , , , ,

Microsoft has lost its appeal to the US Supreme Court.

Microsoft had argued it should have to prove its claim that i4i’s patent was invalid by “a preponderance of the evidence”.

Under the US Patent Act, however, a patent having been granted after examination by the Commissioner is “presumed valid”. The US Supreme Court has ruled that “presumed valid” in this context had a settled common law meaning which Congress was presumed to have adopted. As a result, Microsoft had to make its invalidity case “by clear and convincing evidence”. That is, there is a strong presumption of validity in the USA.

Microsoft Corp v i4i Limited Partnership

Initial commentary by Patently-O.

The case initially attracted international attention as Microsoft was ordered to stop selling versions of Word which had the capability of opening a .XML, .DOCX, or .DOCM file (“an XML file”) containing custom XML. This presumably means that Microsoft will have to pay the US$290 million damages awarded against it for infringement.

Under Australian law, a person alleging a granted patent is invalid has the onus of proof on the usual balance of probabilities standard.

A person opposing the grant of a patent, however, has to establish their case on the clear and convincing or practically certain standard. The exposure draft of the “Raising the Bar” amendment legislation proposes changing that standard, and the standard for acceptance, to the balance of probabilities standard too. (See items 14 and 15 of Sch. 1 (pdf) and pp 26 – 30 of the (draft) EM (pdf).

Patently-O speculates from the voting alignment of the current Court that the US Supreme Court is now shifting “to the right” or “pro-patentee”.

Government responses to ACIP enforcement reviews

Leave a Comment / Enforcement, Patents, PBR / / / , , , , , ,

The Government has announced its responses to ACIP’s reviews of:

On a quick skim, the main recommendation to introduce a Patents Tribunal to determine “IP” disputes has been found non-viable due to the limitations on the Commonwealth’s repository of judicial powers. With WIPO’s arbitration and mediation service in mind, however, IP Australia is to work with alternative dispute resolution providers to provide a new ADR resource. In the PBR context, the Government states that it does not consider it appropriate for IP Australia, as a regulatory agency, to provide post-grant mediation services itself.

The review on PBR has received rather mixed results.

The Government has not accepted the proposal to introduce a “purchase” right.

The PBR Act will be amended to clarify that harvested material which can also be used as propagating material qualifies as propagating material for the purposes of the Act’s prohibitions.

The Government accepts that no changes to the operation of ss 14 and 15 are required.

At this stage, the Government considers that the making of “mendacious” declarations of PBR is adequately covered by the prohibitions on misleading or deceptive conduct in trade or commerce.

Lots of recommendations for more education.

No doubt, you will have your own favourite recommendation(s), but (as I am not a Kat, ip or otherwise) that is all there is time for today!

Inducing patent infringement in the USA

Leave a Comment / Copyright, Patents / / / , , , , , ,

The US Supreme Court has ruled that liability for inducing infringement of a patent under US law requires knowledge of the patent or something called ‘wilful blindness’ to the patent’s existence.

Patently-O summarises and includes a link to download Global-Tech Appliances, inc. v. SEB S.A.

Now, I do know that their law is different to our law.

For a start, under our law infringement can lie in ‘authorising’ the infringer, not (just) inducing the infringement or that idea of contributory infringement – the patentee’s exclusive rights under s 13 include the right to authorise someone to exploit the patent as well as to exploit the patent.

In Ramset, the Full Court traced the old case law: you couldn’t be liable for ‘merely facilitating’ someone else to infringe by supplying materials to them, even if you knew they were going to use them to infringe. If your involvement was sufficient to amount to a common design, or procuring their infringement, however, which generally seemed to presuppose some knowledge of the patent – you could be liable.

Ramset itself knew of the patent’s existence in 1987, several years before it issued the brochure with instructions on how to assemble its product and use it in a way that infringed.

But, on general principles, liability for authorisation requires two elements: (1) that someone has done something which infringes the patent (or threatens to do so in a quia timet case) and (2) the alleged authoriser has done something, or may be supplied something, to entice (to use yet another synonym), induce, persuade or encourage the first person to do that infringing conduct.

The first person, the primary infringer, can be liable even if they do not know that there is a patent – they might escape liability for damages or an account in view of their innocence: see s 123. Why shouldn’t that also apply to the alleged authoriser. Indeed, s 123 would seem equally applicable to the alleged authoriser. And that indeed is the position that Bennett J has reached in Inverness Medical Switzerland GmbH v MDS Diagnostics Pty Ltd [2010] FCA 108, for example.

The copyright cases on authorisation go so far as to hold that, at least in some circumstances, a person who stands by with knowledge that infringing conduct is occurring, or may be is likely to occur, will be liable as an authoriser where they have power to do something about it. Perhaps, we’ll get a better understanding of what is the quality of that power to do something if the High Court grants special leave to Roadshow in the iiNet case.

Amazon’s 1-click in Australia

Leave a Comment / Patents / / / , , , , , , , ,

On Telstra’s opposition to the grant of Amazon’s 1-click patent in Australia, the Commissioner’s delegate has found that:

  • claims 1, 2 and 4 to 61 were invalid;
  • but:

It seems to me that the use to which server generated client identifiers [i.e., cookies] are put in the present invention is both an elegant and inventive way of achieving one action ordering functionality. Therefore I consider that any of the claims having this integer fulfil the requirement of subparagraph 18(1)(b)(ii) of involving an inventive step. These are claims 3 and 62 to 141.

Patentology has a detailed consideration here.

Just noting this as a matter of record:

One week after Apple sued Samsung, Samsung sued Apple for patent infringements, apparently in 4 countries. One point of interest is that this is not Samsung’s defence to Apple’s claims, but is filed so soon after Apple went to court.
