I OVERVIEW

Historically, there has been relatively little patent litigation in Ireland, in particular litigation that progressed to full trial. However, in light of a significant growth in the pharmaceutical industry, with international pharma companies basing worldwide manufacture in Ireland, in recent years there has been a significant rise in patent litigation, particularly in pharma disputes.

Patent law in Ireland is governed by the Patents Act 1992, as amended (the Irish Patents Act). The Patents Rules 1992, as amended (the Patents Rules), generally read alongside the Irish Patents Act, prescribe various procedural rules. As Ireland has a common law legal system, Irish patent law is not derived solely from the Irish Patents Act, but also from the decisions of the Irish courts, for example, interpreting various provisions of the Irish Patents Act.

The provisions of the Irish Patents Act apply equally to national Irish patents granted by the Irish Patent Office (Irish patent) and to European patents designating Ireland, granted by the European Patent Office (EPO).2

An application for a patent conferring protection in Ireland can be made either to the Irish Patents Office, for an Irish patent, or to the EPO for a European patent designating Ireland. Alternatively, in an application made to the World Intellectual Property Organization, under the Patent Cooperation Treaty, the EPO may be designated and then Ireland may be subsequently designated before the EPO.

II TYPES OF PATENTS

Irish patents can be subdivided into two categories: full-term patents (where the term of protection is 20 years from the patent filing date)3 and short-term patents (where the term of protection is 10 years from the patent filing date).4 They are mutually exclusive – they cannot both exist for any one invention.

Short-term patent applications are generally less costly. The distinctive features of short-term patents are set out in Part III of the Irish Patents Act.

i Patentability

Under the Irish Patents Act, an invention shall be patentable if it is susceptible of industrial application, is new and involves an inventive step.5

The Irish Patents Act provides that an invention will be susceptible of industrial application if the invention can be made or used in any kind of industry, including agriculture.6

Further, an invention shall be novel if it does not form part of the state of the art.7 'State of the art' means everything made available to the public, anywhere in the world before the date of filing of the patent application.8

An invention will be considered to involve an inventive step if the invention would not have been obvious to a person skilled in the art, based on the entire state of the art at the date of filing.9

ii Exclusions to patentability

A patent cannot be granted in respect of the following inventions:10

    1. a discovery, scientific theory or mathematical method;
    2. an aesthetic creation;
    3. a scheme, rule or a method for performing a mental act, playing a game, doing business or a program for a computer;
    4. the presentation of information;
    5. inventions where commercial exploitation would be contrary to public order or morality;
    6. a plant or animal variety or a biological process for the production of plants or animals other than microbiological processes and products thereof; or
    7. a method for treatment of the human or animal body by surgery or therapy and a diagnostic method practised on the human or animal body.11

iii Application – securing a patent

An application for an Irish patent must relate to one invention only or to a group of inventions so linked as to form a general inventive concept.

Every application for an Irish patent must be filed with the Irish Patents Office and must contain a request for the grant of a patent, a specification (containing a description of the invention, one or more claims and any drawing referred to in the description or claim) and an abstract.12 The claims must define the matter for which protection is sought. They must be clear and concise and must be supported by the description.13

Ireland is a party to the Paris Convention, and thus the principle of priority applies to Irish patent applications in Ireland. Once a patent application has been filed in Ireland, the applicant is entitled to claim the priority date of that application in respect of all other applications for the same invention made in other states that are signatories to the Paris Convention or are members of the World Trade Organization.

iv Examination

The examination of an Irish patent is carried out by the Controller of Patents, Designs and Trade Marks (the Controller).

Once the Controller is satisfied that the invention meets the requirements of the Irish Patents Act, a patent will proceed to grant. Upon payment of the fee by the applicant, the grant becomes formalised. Once formally granted, the Controller publishes a notice of the grant and a brief specification of the patent in the Journal of the Irish Patents Office. The patent takes effect from this date of publication in the Journal of the Irish Patents Office, and will continue in existence (subject to the payment of annual renewal fees) for the duration of the patent term.

In relation to Irish designated European patents, where a European patent is granted in English and designates Ireland, the patent becomes automatically validated.

v Extension of Irish patents

The Irish Patents Act does not allow for the extension of an Irish patent.

However, supplementary protection certificates (SPCs) are permissible in two sectors: agrochemicals and pharmaceuticals. SPCs can extend the period of protection to a maximum of 25 years.14 Importantly, the patent term is extended only in respect of the specific product, not the entire scope of the claims.

III PROCEDURE IN PATENT ENFORCEMENT AND INVALIDITY ACTIONS

i Fora for patent actions

High Court

There are no specialised patent courts in Ireland and proceedings are not heard by specialist patent judges. Patent proceedings in respect of infringement and revocation must be heard by the High Court (except in certain instances that are set out below) and may be transferred to a division of the High Court known as the Commercial Court.15 Cases heard by the Commercial Court are subject to efficient case management procedures,16 intended to provide a faster track to trial and to minimise costs.

The Circuit Court

Patent infringement proceedings concerning short-term patents may be heard by the Circuit Court.17 While the Circuit Court is a court of (generally) limited and local jurisdiction, patent proceedings involving short-term patents can be brought irrespective of the value of the claim.

The Controller

While patent revocation proceedings are typically brought before the High Court, applications for revocation may also be made to the Controller.18 Proceedings before the Controller are governed by rules set out in Part VIII of the Patents Act 1992 and in the Patent Rules 1992.

ii Standing to bring patent infringement claims

Actions for infringement of a patent may be brought by the proprietor of a patent in respect of any act that the proprietor is entitled to prevent under Sections 40–43 and Section 45 of the Irish Patents Act.19

Where there are two or more joint proprietors of a patent, each joint proprietor has standing to bring infringement proceedings without the concurrence of the others provided that the remaining joint proprietors are named as defendants in the proceedings.20

The holder of an exclusive licence under a patent has the same standing as the proprietor to bring proceedings for acts of infringement committed from the date of the licence.21 Unless the proprietor is a co-plaintiff, it must be joined as a defendant in the proceedings.

iii Standing to bring patent invalidity claims

Any person may apply to the High Court or to the Controller under Section 57 of the Irish Patents Act for revocation of a patent.

iv Limitation periods

The Irish Patents Act does not specify a limitation period within which an infringement action can be issued.

v Commencing patent proceedings

Prior to commencing infringement proceedings, a cease and desist letter is typically issued. Such pre-action letters must be carefully drafted to avoid liability under Section 53 of the Irish Patents Act, which provides remedies for a party that receives a groundless threat of infringement proceedings. Similarly, a letter before action is often issued prior to commencing invalidity proceedings.

The initiating pleading for patent infringement proceedings is a plenary summons, which outlines the essential claim made and the remedies sought by the plaintiff.22 In response, the defendant delivers and files an entry of appearance that requires the plaintiff to deliver a statement of claim and confirms which lawyer will represent the defendant.

Patent invalidity proceedings are commenced by way of a petition for revocation, which must be accompanied by Particulars of Objections.23

At this point, an application is generally made by either party to transfer the proceedings into the Commercial Court list.

vi Exchange of further pleadings

In infringement proceedings, the next step is the delivery by the plaintiff of a statement of claim setting out the particulars of the alleged infringement.24 The defendant is then required to deliver a defence.

In invalidity proceedings, no statement of claim is delivered as the petition is accompanied by the particulars of objection. The next step is for the proprietor of the patent to deliver a defence to the petition and particulars of objection. A defendant who, under Section 57 of the Irish Patents Act, counterclaims for revocation shall deliver with his or her counterclaim the Particulars of Objection to the validity of the patent on which he or she relies in support of the counterclaim.25

After the defence (or, if applicable, the reply to defence) is delivered, the pleadings are considered to be closed.

vii Discovery and evidence

Discovery

General procedural rules regarding discovery are set out in Order 31 of the Rules of the Superior Courts (RSC). Under Irish law, either party to litigation may seek discovery of documents that are or have been in the 'possession, power or procurement' of the other party.

Discovery is generally agreed or ordered by reference to categories of documents, and reasons must be set out as to why each category of documents meets the criteria of relevance and necessity.

In 2016, the Court of Appeal in Boehringer Ingelheim Pharma GmbH & CO KG v. Norton (Waterford) Limited t/a Teva Pharmaceutical Ireland considered and summarised the legal principles applicable to discovery in patent cases.26

Expert evidence

Expert witnesses play a significant role in patent litigation. An expert witness owes a duty to the court to assist on matters within his or her field of expertise.27 This duty overrides any duty he or she has to the party instructing him or her.

The court assesses the teachings and scope of a patent through the eyes of 'the person skilled in the art'. In considering and determining these matters, the court must 'don the mantle' of the skilled person 'to arrive as closely as it can to the mental attitude of a well-instructed representative of the class to whom the specification is addressed, and no more'.28

It is the expert witnesses who assist the court in adopting the mindset of the skilled person. The skilled person has imputed to him or her the 'common general knowledge', which is, essentially, the standard technical background of the art in question. The expert witness must prepare an expert report or witness statement that is exchanged between the parties and ultimately submitted to the court. The expert generally provides oral testimony and can be cross-examined as to their evidence in chief.

Additionally, a person (an assessor) who is 'specially qualified in the opinion of the court' can be appointed by the court to assist on technical issues.29 Their function is to assist the judge in understanding the evidence before the court.

Experiments

In appropriate cases, experiments may be ordered upon the application of a party that wishes to establish a fact by experimental proof.

Pre-action disclosure – methods for obtaining evidence and information

Proceedings may be taken directly against a party to obtain discovery of documents identifying alleged infringers by way of a Norwich Pharmacal order.

Although not strictly limited to pre-action relief, a claimant alleging patent infringement may apply for an order requiring the disclosure by relevant persons (including a person found in possession of infringing goods, or found using infringing services, on a commercial scale) of information regarding the origin and distribution networks of allegedly infringing goods and services.30

The High Court and Commercial Court may also grant Anton Piller orders (preservation orders where documents and items may be seized by the moving party), where there is a serious risk that articles or documents vital to a party's case may be imminently destroyed or otherwise disposed of.

viii Presenting and proving materials in court

Generally, materials may be presented and relied upon at a hearing on the merits only when proven (or verified). Documents are generally admitted via affidavits (sworn statements) or witness statements. The Commercial Court generally directs that written witness statements be exchanged in the lead up to the trial. These form the basis of the evidence given orally at trial and upon which the witness is cross-examined.

ix Amendment of patents in the course of proceedings

The Irish Patents Act permits the High Court (and thus the Commercial Court) or the Controller, in the course of invalidity proceedings, to allow the patent proprietor to amend a patent's specification and claims.31

Such amendments cannot extend the subject matter of the patent,32 and are deemed to have effect from the date of grant of the patent.33 In re Norton Healthcare Ltd,34 the court exercised its discretion to grant the patentee leave to limit the claims of their patent in the event that the existing claims were found invalid.

x Challenge to the validity of the patent

Pursuant to Section 61 of the Irish Patents Act, a defendant may challenge the validity of a patent in infringement proceedings. This challenge is frequently in the form of a defence and/or a counterclaim to an action for infringement.

Section 58 of the Irish Patents Act specifies five grounds on which an application for revocation can be grounded:

(a) the subject-matter of the patent is not patentable under this Act;

(b) the specification of the patent does not disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art;

(c) the matter disclosed in the specification of the patent extends beyond that disclosed in the application as filed, or, if the patent was granted on an application which by virtue of section 24 or 81 is deemed to have been filed on the date of filing of an earlier application, it extends beyond that disclosed in the earlier application as filed;

(d) the protection conferred by the patent has been extended by an amendment of the application or the specification of the patent;

(e) the proprietor of the patent is not entitled thereto under section 16 (1).

If a defendant challenges a patent's validity as a defence in infringement proceedings, the two matters will run in tandem.

xi Timing to first-instance decision for patent proceedings

One would generally expect a patent dispute (either infringement or patent invalidity proceedings) to take approximately nine to 18 months from the issuing of proceedings to the hearing of the trial, depending on the complexity of the case, the extent of discovery and where the court vacations fall. Shorter expedited timelines to trial can, however, be granted in appropriate cases and an expedited trial could begin within six months.

xii Costs of patent proceedings

Patent litigation costs awards are discretionary, but the usual rule is that costs 'follow the event', and are awarded to the successful party. However, orders are generally only for what are termed 'party and party costs'. Party and party costs will cover only the main items in litigation and will not cover the entire costs. In general, somewhere between one-half and two-thirds of the total legal costs incurred are recoverable. Where the parties cannot agree on quantum, the assessment of costs can be listed before the Taxing Master, who will settle the figure to be paid.

xiii Preliminary injunctions

In an appropriate case, a preliminary injunction can be obtained by a plaintiff quickly. An interim injunction can be obtained almost immediately (within a day or so). This is applied for ex parte and lasts until an inter partes application can be heard. At the inter partes hearing, the plaintiff can apply for an interlocutory injunction that lasts until the trial. An interim injunction is only appropriate where there is extreme urgency on the part of the plaintiff and the court can be satisfied that there is good reason to grant such relief.

In most cases, the first and most common type of injunction sought is a preliminary interlocutory injunction. An application for a preliminary injunction can only be made as part of full plenary proceedings. Overall, the plaintiff must demonstrate that the matter is extremely urgent and that it cannot wait for a full trial to receive a final injunction. To obtain a preliminary interlocutory injunction, a plaintiff must show that:

    1. it has raised a fair question to be decided at the trial of the action;
    2. damages would not be an adequate remedy for it; and
    3. the balance of convenience favours the granting of the injunction.35

An application for such an injunction is generally heard within four to six weeks.

The Irish courts are slow to grant preliminary injunctions because of the general difficulty in patent matters in showing that damages would not be an adequate remedy for the applicant. In April 2018, the High Court again refused to grant a preliminary injunction in an SPC infringement case as it found that damages would be an adequate remedy for the SPC holder. The refusal of the preliminary injunction was upheld by the Court of Appeal36 in a 2 to 1 majority decision on the basis that damages would be an adequate remedy for the SPC holder. This was the first time the Court of Appeal considered the issue in Ireland and the two assenting judges agreed that damages were an adequate remedy for the plaintiff patentee or SPC holder in that case.

xiv Condition and security requirements for interim relief to be granted

The plaintiff must give an undertaking in damages in the event that he or she should fail at trial. This is an undertaking that, if the injunction is granted but is subsequently found to have been wrongly given, the plaintiff will compensate the defendant for any losses incurred as a result of the injunction.

IV SUBSTANTIVE LAW

i Infringement

Under the Irish Patents Act, the following acts, if done without the proprietor's consent within the territory of Ireland, amount to direct patent infringement:

(a) making, offering, putting on the market or using a product which is the subject matter of the patent, or importing or stocking the product for those purposes;

(b) using a process which is the subject matter of the patent, or, when the third party knows, or it is obvious to a reasonable person in the circumstances, that the use of the process is prohibited without the consent of the proprietor of the patent, offering the process for use in the State;

(c) offering, putting on the market, using or importing, or stocking for those purposes, the product obtained directly by a process which is the subject-matter of the patent.37

Further, it is an indirect infringement of a patent for a third party, without the consent of the proprietor of the patent, to supply or offer to supply in the territory of the State a person, other than a party entitled to exploit the patented invention, with means, relating to an essential element of that invention, for putting it into effect, when the third party knows, or it is obvious in the circumstances to a reasonable person, that the said means are suitable and intended for putting that invention into effect.38

ii Construction

The Irish Patents Act provides that:

[T]he extent of the protection conferred by a patent or a patent application shall be determined by the claims; nevertheless, the description and drawings shall be used to interpret the claims.39

Although in Ireland there is no general doctrine of equivalents, the Irish Patents Act does provide that, when interpreting this section:

[T]he Court shall have regard to the directions contained in the Protocol on the Interpretation of Article 69 of the European Patent Convention and set out in the Second Schedule to this Act.40

The Irish courts (both the High Court41 and the Supreme Court42) have approved the approach taken by the UK courts in Kirin-Amgen Inc v. Hoechst,43 namely, a purposive construction rather than a purely literal one, giving the language of the claim the meaning that would have been understood by the notional addressee – the person skilled in the art.

The recent decision of the UK Supreme Court, in Eli Lilly v. Actavis,44 may be of persuasive value to an Irish Court where issues of construction come before it.

iii Defences – statutory exceptions to infringement

Under the Irish Patents Act, the rights conferred by a patent do not extend to:45

    1. acts done privately for non-commercial purposes;
    2. acts done for experimental purposes relating to the subject-matter of the relevant patented invention;
    3. the extemporaneous preparation for individual cases in a pharmacy of a medicine in accordance with a medical prescription or acts concerning that medicine;
    4. use of the invention on board certain vessels or aircrafts that temporarily or accidentally enter the territory of the State;
    5. acts specified in Article 27 of the Convention of International Civil Aviation; and
    6. acts falling under the Bolar exemption.46

iv Other defences

In addition, a defendant may claim that the patentee has exhausted its rights. In short, the principle of exhaustion of rights provides that a patent cannot be used to prevent a third party from importing goods that have been put on the market in another Member State by the patentee or with his or her consent.

Further, a defendant may claim that it has a right to continue use that had begun before the filing or priority date, provided such acts are done in good faith.47

Finally, a defendant may plead that neither damages nor an account of profits should be awarded, on the basis that he or she can prove that at the date of the infringement he or she was not aware, and had no reasonable grounds for supposing, that the infringed patent existed.48

V FINAL REMEDIES FOR INFRINGEMENT

If a patent is found to be infringed, or where a litigant's claim is otherwise successful, a range of remedies may be available. These include the following.

i Monetary remedies

Pursuant to Section 47 of the Irish Patents Act, damages or an account of profits (but not both) can be awarded for the infringement of an Irish patent. It is ultimately at the discretion of the court to decide which is appropriate.

Damages are compensatory in nature and are predominantly calculated by way of assessing loss of profits. Alternatively, damages can be calculated based on the sum of money the infringing party would have had to pay as royalties.

An account of profits is a calculation of the profit made by an infringing party as a result of its infringing activities. An account of profits is intended to prevent unjust enrichment and to restore the patent holder to the position it would have been in had the infringement not occurred.

The court will not award either remedy as against an 'innocent infringer', where an infringing party was not aware and had no reasonable grounds to know that the patent existed.49

ii Non-monetary remedies

Injunctions

Permanent injunctions50 can be sought to restrain an infringing party from 'any apprehended act of such infringement'. Injunctions can be prohibitory or mandatory – as was seen in Smithkline Beecham plc v. Genthon BV51 – and are routinely granted at the conclusion of infringement proceedings.

The court ultimately has discretion to refuse a final injunction, and will in some instances impose a licence in lieu of a permanent injunction.

Delivery up or destruction

Pursuant to Section 47(1)(b) of the Irish Patents Act, the court can order the delivery up or destruction of infringing goods.

Declaration

Where a patent holder is successful in his or her infringement proceedings, the infringing party is declared to have infringed the patent. Furthermore, an order for the publication of the judgment can be made by the court at the request of the patent holder.52

VI OTHER TYPES OF PATENT PROCEEDINGs

i Declarations of non-infringement

Any person may apply to the High Court for a declaration that its acts, or proposed acts, do not infringe a patent (a declaration of non-infringement: DNI).53 The validity of the patent cannot be challenged in proceedings for a DNI, and the making or refusal of a DNI does not imply that the patent is valid.54

ii Compulsory licences

At any time after the expiration of the period of three years beginning on the date of the publication of notice of grant of a patent, any person may apply to the Controller for a licence under the patent, or for an entry in the register to the effect that licences under the patent are to be available as of right.55

iii Disputes regarding entitlement to ownership of a patent

Under the Irish Patents Act any person can request that the High Court determine entitlement to ownership of a granted patent.56

VII APPEAL

Decisions of the Controller can be appealed to the High Court.57 There is an automatic right of appeal of every decision of the High Court (including the Commercial Court) to the Court of Appeal. This is not limited to a decision on the merits and includes interlocutory decisions such as preliminary injunction orders. An appeal does not operate as an automatic stay. The court has discretion to decide whether or not to grant a stay.

To appeal against a High Court order, the appellant must lodge a notice of appeal within 10 days (for an expedited appeal)58 or within 28 days (for an ordinary appeal) of the date when the High Court order is perfected.

In certain limited circumstances, there is a possibility of a further appeal to the Supreme Court, where (1) a the decision involves a matter of general public importance; or (2) it is necessary in the interests of justice that there be an appeal to the Supreme Court

Additionally, direct appeals (from the High Court) to the Supreme Court will be allowed where (1) a the decision involves a matter of general public importance; or (2) it is necessary in the interests of justice that there be an appeal to the Supreme Court; and (3) exceptional circumstances warrant a direct appeal.

VIII THE YEAR IN REVIEW

There has been a flurry of patent cases, both infringement and invalidity proceedings, before the Irish courts over the past 18 months.

One of the most interesting invalidity actions to be decided by the Irish Commercial Court is Norton (Waterford) Limited t/a Teva Pharmaceuticals Ireland's application to revoke the Irish designation of European Patent No. (IE) 1379220, owned by Boehringer Ingelheim Pharma GmbH & Co. KG. The judgment of Barrett J delivered on 26 July 201759 provides a long awaited decision on various aspects of patent law including obviousness, an 'AgrEvo' challenge and insufficiency. Additionally, an earlier Court of Appeal decision in the same case, handed down in February 2016, provides an excellent summary of the legal principles applicable to discovery in patent cases, in particular the issue of proportionality.60

Further, in respect of infringement proceedings as mentioned above the Court of Appeal has, for the first time, adjudicated on a preliminary injunction application in respect of alleged patent infringement. This decision, which was handed down in April 2018, confirms the approach taken in many previous cases that damages would be an adequate remedy for the plaintiff and the application for an interlocutory injunction was refused by the Court of Appeal and High Court.

Prior to that, in November 2017, the High Court heard an application by Gilead Sciences Inc (and others) for an injunction against various Mylan and Teva entities based on its SPC in respect of the defendants' generic version of Gilead's HIV drug Truvada. In refusing to grant the injunction, the High Court held both that damages would be an adequate remedy for the plaintiff and that such damages were capable of assessment.61

IX OUTLOOK

One of the hot topics in terms of Irish patent law will be the ratification of the UPC Agreement, which will require a referendum to amend the Irish Constitution. It was anticipated that this referendum would take place over the course of 2018 but this is no longer the case and Ireland is unlikely to hold any such referendum before the uncertainty surrounding the UPC subsides.

A recent enactment now requires solicitors to advise their clients of the advantages of mediation as an alternative to issuing proceedings. Therefore, it is possible that prospective parties to patent proceedings might engage in discussions to reach an amicable resolution at an early stage. However, how this will play out in practice remains to be seen.
