Further undertakings, a stay -- and an expression of hope

Last week PatLit reported on the refusal of Mr Justice Arnold, in Actavis Group PTC EHF v Pharmacia LLC [2014] EWHC 2265 (Pat), to grant a stay of patent revocation proceedings in England and Wales pending the outcome of parallel opposition proceedings before the European Patent Office. On Thursday of last week, in [2014] EWHC 2611 (Pat), the same judge delivered a further judgment in which he granted a stay, having considered the effect of two further undertakings from Pharmacia. This judgment is not yet on BAILII but, since it is only seven paragraphs long, PatLit is reproducing it below in full:
1. This is a renewed application by Pharmacia for a stay of these proceedings until the final determination of the parallel proceedings before the European Patent Office. The background is set out in full in my judgment of 11 July 2014 ([2014] EWHC 2265 (Pat), and I will not repeat it here. As was set out in the postscript to that judgment at paragraph 33, following the circulation of a draft of the judgment to the parties, Pharmacia offered two additional undertakings in return for a stay of the proceedings. Those additional undertakings are summarised in paragraph 33 of the previous judgment and have subsequently been elaborated, together with the other undertakings offered by Pharmacia, under cover of a letter from Pharmacia's solicitors dated 23 July 2014.

2. Against that background, Pharmacia now seeks a stay of the proceedings on the basis of all of those undertakings. As can be seen from paragraphs 30 and 31 of my previous judgment, I concluded that a stay should not be granted on the basis of the undertakings offered by Pharmacia set out in paragraph 12 of that judgment. As I stated, it seemed to me that the competing considerations were finely balanced, but nevertheless they favoured the refusal of a stay. The key consideration that weighed with me in reaching that conclusion was that, having regard to the likely length of time it would take for the EPO proceedings to be resolved, the undertakings that were offered by Pharmacia, although they largely eliminated the commercial uncertainty to Actavis during the period of stay, did not address the uncertainty caused by the prospect that Actavis might be removed from the market by an injunction in, say, five years' time and might have to pay ordinary damages or account for its profits for the last two of those years.

3. In my view, the additional undertakings now offered by Pharmacia meet that point, and accordingly do substantially eliminate the commercial uncertainty to which Actavis will be exposed in the United Kingdom as a result of a stay.

4. Actavis continues to resist a stay even on the basis of the additional undertakings proffered by Pharmacia. Actavis’ reasons for resisting a stay are set out in paragraphs 9 19 of the third witness statement of Mark Hilton of Actavis’ solicitors. In summary, the key points that Mr. Hilton makes on behalf of Actavis are twofold. First, he makes the point that Actavis wishes to launch its generic sustained release pramipexole product throughout Europe. Accordingly, Actavis wishes to remove the commercial uncertainty caused by the existence of the Patent as soon as possible across Europe. Actavis takes the view that an early decision from this court will be of considerable assistance to it in that regard. It will give Actavis and its customers confidence as to the position across Europe. Furthermore, it is likely to be of persuasive effect in other jurisdictions. The second main point made by Mr. Hilton follows on from the first, namely that an early decision of this court will assist in promoting settlement between the parties on a pan European basis. An additional point Mr Hilton makes, which to my mind is of less weight than the two main points, is to suggest that it is clear from Pharmacia’s attitude and the undertakings that it has offered that the Patent is a weak one, and that there is a strong public interest in the validity of weak patents being scrutinised by a competent court at the earliest possible date.

5. In my judgment, the matters that are relied upon from Actavis are considerations which do favour the refusal of a stay. Nevertheless, I have to consider the overall balance, having regard to the guidance given by the Court of Appeal in IPCom GmbH v HTC Europe Co Ltd [2013] EWCA Civ 1496, [2014] RPC 12, at paragraph 68. Taking all of the factors set out in that judgment into consideration, it seems to me that the overall balance now comes down in favour of the grant of a stay. While I accept that Actavis has a good reason to want to obtain a decision of this court at an early date and that that will be of assistance to Actavis in the ways that Mr. Hilton describes, I nevertheless consider that the additional undertakings offered by Pharmacia go sufficiently far to tip the balance in favour of a stay, having regard to the other factors mentioned in IPCom.

6. For those reasons, I will now grant a stay on the basis of the undertakings set out under cover of Pharmacia's solicitors’ letter dated 23 July 2014 as clarified with counsel for Pharmacia this morning.

7. I should say one thing further, which is this. Counsel for Actavis made the point that, although Pharmacia has offered an undertaking to co operate with Actavis to seek expedition of the opposition proceedings in the EPO, including any appeal to the Board of Appeal, there was room for doubt as to whether the EPO would accede to a request for acceleration, given that Pharmacia has offered an undertaking not to seek an injunction in the UK. I acknowledge the force of that point. However, it seems to me to be clear that expedition of the EPO proceedings is warranted not merely because of the existence of the English proceedings, which will include the counterclaim for infringement that Pharmacia has undertaken to bring. It seems to me to be plain from the current position of the parties that there is a strong likelihood of further proceedings elsewhere in Europe and, furthermore, a strong likelihood that those further proceedings will include infringement proceedings in one or more contracting states of the EPC. Accordingly, I express the hope that the EPO will accede to the joint request of the parties to accelerate the opposition proceedings and any appeal.
That the EPO should expedite proceedings is clear; whether it will take note of the hope of a British trial judge or of the parties themselves is however less certain.   Do readers of this weblog have any evidence, anecdotal or otherwise, of the EPO accelerating proceedings because a national court has expressed the wish that this should happen?

Expert can be "too clever" and still do his job

Rovi Solutions Corporation & Another v Virgin Media Ltd & Others [2014] EWHC 2301 (Pat) is a decision of John Baldwin QC (sitting as a Deputy Judge of the Patents Court, England and Wales) earlier this month. The subject of the judgment, in the fourth of a series of actions in which Rovi was suing Virgin, was the validity of a patent belonging to Rovi.  This blogpost is just focusing on one element of the judgment: the court's assessment of the role of the expert witness:

The judge said, at [14] to [16]:
"14. The expert witness instructed by Virgin was Mr Kerr. He was a business/IT consultant with extensive experience in the telecommunications, multimedia and TV areas up to 2001 and, subsequently, in more general communications and IT systems. His experience and expertise in the interactive TV/VOD arena spanned 19 years from 1981 to 2000. During this time he covered system-level architectures, designs and performance.

15. Mr Kerr was a very impressive and knowledgeable witness who was able to explain concepts clearly and succinctly. I found him very helpful.

16. Mr Abrahams, counsel for Rovi, had two main criticisms. The first was that Mr Kerr was much too clever and imaginative to be able to give an opinion upon what the skilled addressee might learn from a document or what the skilled addressee might do in consequence of any teaching in a document. But, as Jacob LJ explained in Technip France SA's Patent [2004] RPC 46 at [11] – [15], it does not really matter whether or not the expert approximates to the skilled team, what matters is how good he is at explaining things and what are the reasons for his opinion".
It's good to be reminded that being too clever needn't be a bar to discharging one's duties as an expert witness though, presumably, when it comes to issues of inventive step, some expert witnesses will be valuable to a party defending the validity of its patent if they're neither that clever or that imaginative.

This blogger is sad that the judge's quote began at [11], when [10] is the bit that contains one of Jacob LJ's most memorable lines. Speaking of the person skilled in the arts:
"The man can, in appropriate cases, be a team – an assembly of nerds of different basic skills, all unimaginative. But the skilled man is not a complete android, for it is also settled that he will share the common prejudices or conservatism which prevail in the art concerned".

No stay: balancing justice, speed and the chilling effect of uncertainty

Actavis Group PTC EHF v Pharmacia LLC [2014] EWHC 2265 (Pat), decided earlier this month by Mr Justice Arnold in the Patents Court, England and Wales, is yet another case involving an application for a stay. There sometimes seem to be more applications for stays than there are substantive proceedings, which says a lot about the way in which litigants have to struggle with a multitude of jurisdictions and causes of action in the Europe of today.

In this case Pharmacia owned a European patent relating to sustained release dosage forms of pramipexole, a product used for the treatment of Parkinson’s disease and restless leg syndrome. Actavis applied to revoke the United Kingdom designation of this patent on various grounds, there being parallel opposition proceedings relating to the same patent before the European Patent Office (EPO).

A dispute arose as to how quickly the EPO proceedings were likely to be resolved, both without and with expedition, and taking into account a possible appeal to the Board of Appeal and the remission of the case  by the Board of Appeal to the Opposition Division. Pharmacia then sought a stay of the UK revocation proceedings until the EPO proceedings had finally ground to a halt, while offering a number of undertakings as a sort of sweetener. These were (i) to seek expedition of the EPO proceedings, (ii) not to seek an injunction against Actavis or its customers until the determination of the EPO proceedings and (iii) only to seek damages of 1% of Actavis' net sales during the period from launch until the determination of the EPO proceedings if the patent was held valid both by the EPO and in the UK.

Actavis was unhappy with this, submitting that a stay should be refused because the proceedings regarding the UK segment of the patent would be resolved significantly earlier than the EPO proceedings and that the decision regarding the UK would provide it with reasonable commercial certainty, at least in the UK, and might assist in promoting settlement.

Arnold J, in a brief (33 paragraph) judgment, dismissed the application for a stay.

* the court's discretion to grant a stay of proceedings, which was very wide, should be exercised to achieve the balance of justice between the parties, having regard to all the relevant circumstances of the particular case;

* while that discretion was indeed wide, previous cases suggested that the default option was that the proceedings should be stayed. It was thus for Actavis to show why no stay should be granted.

* resolution of the proceedings before the courts in England and Wales was likely to take two years. In contrast, while both the Opposition Division and the Board of Appeal were likely to expedite the proceedings, neither the fact of expedition nor its outcome could be guaranteed.

* even with expedition, the EPO proceedings were likely to take at least three years to resolve -- possibly considerably more, if the Board of Appeal remitted the case to the Opposition Division.

* if the national proceedings were stayed, the oppositions failed and the national proceedings were then resumed, they would not be resolved until at least five years from now. In terms of commercial certainty, the starting point was to consider what Actavis’ position would be if there were no stay: it would be exposed to commercial uncertainty with regard to its position in the UK during the two years it would take to resolve the national proceedings.

* while the competing considerations were finely balanced, ultimately they favoured the refusal of a stay.

Arnold J's observations concerning the undertakings that Pharmacia was willing to offer is worthy of note. he said, at [30]:
"... Pharmacia's undertakings go a considerable way to reducing the commercial uncertainty to Actavis in the UK if the English proceedings are stayed, but in my judgment not quite far enough. While they do largely eliminate the commercial uncertainty during the period of the stay, and indeed give Actavis the positive benefit of ensuring that it can get on the market during that period rather than having to rely upon a claim under a cross-undertaking in damages, the problem is that they do not address the uncertainty caused by the prospect that Actavis may be removed from the market by an injunction in, say, five years' time and may have to pay ordinary damages or account for its profits for the last two of those years. That uncertainty will inevitably have a chilling effect on Actavis' investment decisions".

No stay of UK patent revocation proceedings in favour of later-filed Northern Irish court action

In Kayfoam Woolfson v Recticel SA & Recticel LtdBL O/315/14, 17 July 2014, UK Intellectual Property Office (UKIPO) hearing officer Phil Thorpe held that the UKIPO did have had jurisdiction to hear an application for revocation of a patent on the basis that the issue of revocation would not more properly be determined by the court.

By way of background, Recticel had already commenced infringement proceedings against Kayfoam in the Intellectual Property Enterprise Court (IPEC), England and Wales. As it happened, Recticel had discontinued its claim before Kayfoam's application for revocation was filed; although Kayfoam had reserved its position without actually opposing the discontinuance of Recticel's infringement proceedings, that reservation did not keep the action alive. Accordingly there was no action pending before the court at the date of filing f Kayfoam's revocation application.

As it happened, Recticel had also commenced infringement proceedings in Northern Ireland (also part of the United Kingdom, therefore covered by the same patent, but with its own separate judicial system).  However, Kayfoam's application for revocation before the UKIPO had been made before Recticel's Northern Ireland complaint was served.

Haqving taken all the relevant factors into account, the hearing officer concluded that this was not one of those cases that would be more properly determined by the court. Both the UKIPO proceedings and the Northern Ireland proceedings were still in early stages, which meant that there wouldn't be too much wastage and inconvenience if a stay were ordered. The stay would however be refused because the present situation was caused by Recticel discontinuing its IPEC action.

"Limitation and Amendments of claims during litigation" -- a report

"Limitation and Amendments of claims during litigation" was the theme of a conference held in Milan last month, the details of which were sent to us by our good friend Anna Maria Stein (Franzosi Dal Negro Setti). Anna Maria promised to keep PatLit informed of what transpired at this attractive event and, true to her word, this is what she says: Dear Jeremy,
This is a short update on the Conference on claims amendments. John Allen made a great speech and he was very appreciated by the audience [and indeed by all of us: see Katpost here].

1. The European Patent Convention allows limitations and modifications of claims after grant. Articles 105(a) and 123 EPC. When this is done at the EPO (central limitation), the effects are regulated (in a not totally clear manner) by Article 68 EPC. But also most national laws allows limitation or modification of claims of granted patents (local limitation). Each member state may behave differently: local limitations are governed by national laws. These laws should be in conformity with the European system, but full conformity is not guaranteed. The result is that a European patent may be modified differently in different States, thus resulting in different national patents, a variable geometry system. The European patent is granted unitarily, but then may be transformed into different titles, with different scope: quite embarrassing.

2. The first day of the Conference the various systems were compared (UK, DE, NL, FR and IT). What is surprising in the system (and to the present writer, somehow shocking) is that the patentee may change the patent at any time. Therefore claims may be changed in the first year after grant, or the second, or the last. They can be changed even after the patent expires. Whether Article 68 EPC mitigates the inconveniences is a question to be considered.

3. On the second day of the Conference a mock trial (or a series of trials) was conducted, and several patent attorneys discussed whether some modifications were allowable and what not. The results were somehow encouraging.

Not forgetting
the Mock Turtle ...
Although, in principle, all national systems have different rules, ultimately those rules could be interpreted in a not too dissimilar manner. This conclusion was evidenced by the mock trial, where six cases of claim modification were discussed. A mock court composed of mock judges of four mock countries (Sir Robin Jacob, Dr Marina Tavassi, Dr Klaus Bacher, Professor Jean-Christoph Galloux, Professor Mario Franzosi) issued a mock decision on the allowability of modifications.

Here's the sample mock patent [which you can read here or download here], with the mock amendments.
These six cases have all been discussed and decided. Adds Anna Maria: "I will let you have as soon as available the text of the decision issued by the panel".  Thanks so much, Anna Maria, we really appreciate this!

Precedent, the European Patent Office and a chance to discuss

"What is precedent and does the EPO have it?" is the title of a blogpost today by Darren Smyth on the IPKat weblog, here, with some input from fellow bloggers David Brophy and me. It raises questions relating to, among other things, the extent to which European Patent Office Board of Appeal and Enlarged Board of Appeal are governed, in theory and in reality, by the principle of being either bound or strongly influenced by their own decisions and those of other tribunals, as well as the extent to which national courts and patent-granting authorities are influenced or bound by them.

The IPKat's colleague Merpel concludes that:
" ... whether a decision is non-binding and non-influential, non-binding but influential, or binding, is a matter that has a substantial impact on players other than the relevant court or tribunal: it affects the decisions of parties whether to file, oppose, litigate and so on. It also affects the decisions of legislators as to whether a rule needs changing or not. If it is consistently applied with a consequence that is considered undesirable, legislative intervention is more likely than where bad decisions are distributed among good ones because the latter are not binding. Therefore, she points out, lack of consistent understanding and terminology between practitioners before the EPO is highly undesirable".
It would be good to hear from practitioners from outside the zone of Common Law countries as well as those who have grown up with the habit of precedent and who intuitively give advice on the assumption that it exists.

The place of patent drawings in IP litigation: a new article

"IP Litigation: What Place for Patent Drawings?" is the title of an article published online in the current (June 2014) issue of the WIPO Magazine. The author, Bernadette Marshall (NBG Drafting and Design, USA), opens by stating that
In today’s ever more complex technology landscape, the number of patent lawsuits is on the rise and patent litigation costs are skyrocketing. This is especially true in the United States where, in 2012, according to a recent study by PricewaterhouseCoopers over 5,000 patent lawsuits – an all-time record – were filed, each costing on average around US$2.8 million. Within this setting, companies should not underestimate the importance of using simple, clear and precise illustrations, not only to enhance their chances of obtaining a patent in the first place, but more importantly to defend their rights in the event of litigation.
You can read the article, which links to Bernadette's earlier WIPO Magazine article "Better Drawings Make a Better Patent", in full here.  Its principal relevance is to the United States, in respect of which the article refers to the US's design patents as well as the conventional sort, but the essential message is that, the more clearly an invention is described, the less room there is for uncertainty, ambiguity and mistake, and that an accurate depiction is likely to help achieve that end.

Secondary Legislation Implementing the Unified Patent Court: a consultation and workshops

The UK Intellectual Property Office (UKIPO) has organised a free webcast for this coming Wednesday 16 July at 4 pm for IP professionals on the following title "Consultation on Secondary Legislation Implementing the Unified Patent Court". 

You can get the details here. Follow-up workshops, run by the UKIPO, are being offered as follows:
  • London, 30 July at 2 pm, hosted by UKIPO
  • Edinburgh, 23 July at 2 pm, at the Law Society of Scotland
  • Newport, 28 July at 2 pm, again hosted by UKIPO
  • Manchester, 31 July at 2 pm, in the offices of Squire Patton Boggs LLP
Spaces are limited for the workshops, so please email UPCconsultation@ipo.gov.uk to reserve your place.

This blogger is conscious of the fact that, being based in the UK, he usually spots what is going on there but often misses parallel developments in other jurisdictions. He therefore wonders whether, and to what extent, the UPC's secondary legislation is under review in other UPC states. 

After Woolf comes Fox: a new book on patent litigation

I've just received the following information concerning a new title from publishers Sweet & Maxwell which is of obvious relevance to patent litigation in England and Wales. The author is Angela Fox, whose many qualifications and virtues are listed on her Jenkins web page here.  The book's subject matter is the functioning of an exciting experiment in civil litigation, very much in the spirit of the Woolf Reforms (here and here) of civil procedure rules.

According to the publishers:
"Intellectual Property Enterprise Court: Practice and Procedure is a unique standalone guide to practice and procedure before the Intellectual Property Enterprise Court, formerly the Patents County Court.

It provides a reference for all litigators and practitioners seeking to make the best use of the court’s unique streamlined procedures for the cost-effective resolution of intellectual property disputes involving UK or Community IP rights.

  • Discusses essential topics including pre-action matters, starting proceedings, case management, applications, evidence, experiments and disclosure, trial, appeals, costs and small claims 

  • Covers the jurisdiction of the Intellectual Property Enterprise Court, the types of proceedings it undertakes and representation before the court, offering practical guidance on navigating the system effectively 

  • Looks at the specialist rules of procedure introduced in 2010 and since that have broadened the Court’s appeal as a forum for resolving IP disputes in a streamlined and cost-effective way 

  • Also considers other dispute resolution mechanisms relevant to claims that may be brought before the IPEC, including domain names and company names, as well as ADR Includes example statements of case for a range of IP subject matter 

  • Draws on a range of sources to present a complete picture, including extracts from relevant source materials, court guides and the Civil Procedure Rules".
More information about this timely book can be obtained from its website here. It costs £165, so I'll wait till I can get hold of a review copy rather than rushing out to buy it myself. Meanwhile, if anyone has any perspectives or insights into it, can they please share them with us.

Playing the game: amendments and double patenting

Koninklijke Philips Electronics NV v Nintendo of Europe GmbH [2014] EWHC 1959 (Pat) is a decision of Mr Justice Birss, Patents Court for England and Wales, going back to 20 June of this year. It's a 452-paragraph judgment, produced pretty speedily by the judge following seven days of hearings just one month earlier.

In short, Philips sued Nintendo, alleging that the latter's Wii computer game console infringed three of its patents for computer implemented inventions. Nintendo counterclaimed for revocation and Philips then applied for conditional amendments to all three patents. The court had to decide on infringement and, inter alia, (i) whether the proposed amendments should be allowed or whether they would introduce added matter; (ii) whether one of the patents was obvious over the prior art, and (iii) whether the two other patents were valid as granted and whether there was an element of double patenting.

Birss J held that all three patents were invalid as granted but that the second and third, when amended, were both valid and infringed. He gave some helpful guidance with regard to double patenting that runs like this (at paragraphs 302 to 310):
  1. First, the idea at the heart of the double patenting objections is that ordinarily an applicant should not obtain two patents for the same thing filed at the same time. That is because an applicant ordinarily has no legitimate interest in doing this [if this is so, should it not then apply equally to other registered IP rights, for example trade marks, where the question of double protection is more complex on account of considerations such as genuine use?].
  1. Second, however "double patenting" is not a ground of revocation of a patent. It is not in s72 of the Act [Patents Act 1977, here] nor Art 138 EPC [European Patent Convention, here]. In the UK there are particular circumstances in which double patenting can lead to refusal (or revocation on the Comptroller's initiative). They are defined by statute (s18(5) and s73(2)).
  1. Third, the EPO does recognise a double patenting objection as a ground for refusing amendments to a divisional application. Two conditions have to be satisfied. The proposed amended divisional claim has to claim the same subject-matter as a parent and the applicant has to have no legitimate interesting in obtaining the divisional claim. Generally if the first condition is true the second is likely to follow but there can be cases, such as T 1423/07 in which a legitimate interest in obtaining the divisional claim can be shown to exist irrespective of the relationship between the scope and subject matter of the parent and divisional claims.
  1. Fourth, the EPO does recognise that if the independent claim of a divisional has the same scope as an independent claim in the parent then double patenting exists and an amendment which would give rise to that state of affairs will be refused. It is a test of substance and not merely form. It is not the settled jurisprudence of the EPO that double patenting exists merely because the scopes of the two claims overlap.
  1. Fifth, one needs to take care when comparing the different procedural circumstances in which this point can arise. The EPO only deals with one patent at a time and so an EPO case considering a divisional application will not contemplate making changes to the claims of the parent to overcome an objection. Although post-grant centralised amendments are now possible in the EPO, that is a fairly recent development. In the UK the point only arises in two very specific statutorily defined circumstances.
  1. Sixth, the judgment of the Court of Appeal in Marley's Roof Tile [1994] RPC 231 is directed to a point on statutory construction of s73(2) of the 1977 Act. Although both s73(2) and the objection applied by the EPO are referred to as "double patenting" and have the same underlying rationale, the Court of Appeal's judgment is not binding on the question arising in relation to the exercise of discretion under s75 of the Act.
  1. Seventh, a patentee may have a legitimate interest in obtaining a divisional patent with claims which are broader than but encompass the scope of a parent patent. During prosecution of the parent the examiner may object to a broad claim but indicate that a narrower claim would be accepted. The patentee may not agree but may recognise that to win the point will need many more months or even years of proceedings and possibly appeals. This is true in both the EPO and UKIPO. However in the meantime the patentee may want to obtain an early grant because a competitor has launched an infringing competitive product [This is where commercial considerations come into play ...]. The infringing product may be very close to the patentee's invention and within the narrow claim on offer. At an early stage in this new market for a new product the patentee's business may be particularly vulnerable and the loss caused by the infringement may well not be fully compensatable in damages under s69 of the 1977 Act (Art 67 EPC). Thus the patentee decides to take what is on offer and obtain grant of the parent patent with a narrow claim. Under s76 of the Act and Art 123(3) EPC post grant amendments are not permitted to widen the scope of monopoly so, in order not to give up scope to which the patentee is entitled, a divisional application is filed. If the divisional is granted with a broader scope than the parent then the patentee's stance has been entirely vindicated.
  1. In my judgment a patentee in the case I have described has a legitimate interest in obtaining the divisional in addition to the parent and it would be wrong to apply a double patenting objection based on overlapping scope such as in T307/07 or Marley's Roof Tile to prevent this. I also do not believe that a disclaimer or carve out amendment from the divisional to remove the scope of the parent claim should be required since such negative features can introduce uncertainty and make the claims hard to interpret.
  1. I find that as a matter of UK law a double patenting objection taken as a ground for refusing a post-grant amendment to a claim can be taken but should only be taken in the following circumstances:
(i) The two patents must have the same priority dates and be held by the same applicant (or its successor in title); 
(ii) The two claims must be for the same invention, that is to say they must be for the same subject matter and by this I mean they must have the same scope. The scope is considered as a matter of substance. Trivial differences in wording will not avoid the objection but if one claim covers embodiments which the other claim does not, then the objection does not arise. 
(iii) The two claims must be independent claims. This necessarily follows from the rejection of the point on overlapping scope. If two independent claims have different scope then there is no reason to object even if the patents contain dependent claims with the same scope. The point might arise later if an amendment is needed e.g. to deal with a validity attack but in the case the point can be taken then. 
(iv) If the objection arises in the Patents Court in which both patents are before the court then it can be cured by an amendment or amendments to either patent. 
(v) Even if the objection properly arises in the sense that two relevant claims have the same scope, if the patentee has a legitimate interest in maintaining both claims then the amendment should not be refused.
Do readers agree with this summary, or does it invite comment and qualification?

SDL wrongful threats case: counterfactual history reaps reward

Almost exactly a year ago, PatLit posted this item on SDL Hair Ltd v Next Row Ltd and others; Master Distributor Ltd v SDL Hair Ltd and others [2013] EWPCC 31, a Patents County Court, England and Wales, decision on, among other things, the making of unwarranted threats of to sue for patent infringement.

Now, in  which emanated last month from Mr Recorder Richard Meade QC. With so much going on, it got overlooked at the time -- but it's still worth noting. Now, in SDL Hair Ltd v Next Row Ltd & others [2014] EWHC 2084 (IPEC), an Intellectual Property Enterprise Court ruling of 3 July 2014, in a 98 paragraph judgment Judge Hacon addresses the question of quantum: how much damage was caused by the making of wrongful threats?  In this case, said the judge, the total loss was £40,500, a sum on which the defendant was required to pay a so-far-unspecified sum of interest.

The judge's decision incorporated his reconstruction of what might have been, had the wrongful threats not been made, by setting out what he termed a "counterfactual history" at paragraphs 54 to 72 of his judgment. While this counterfactual history is obviously highly fact-specific, the approach is one which might expect to see transferred to other situations in which ungrounded threats of patent infringement are made , thus guiding the innocent party's decision whether to sue for damages or not.
