LIDC Activities

Every year, the LIDC organises an international Congress to study in particular two questions related to competition law, intellectual property law and/or unfair competition.

The LIDC further organises Webinars on competition law, intellectual property and unfair competition issues of relevance and interest for its members. Working groups are constituted to study in-depth certain legal developments.

LIDC Annual Congress

Every year, the LIDC organises an international Congress to study in particular two questions related to competition law, intellectual property law and/or unfair competition.

The annual Congress is generally organised by a National Group of the LIDC.

NEXT CONGRESS – LONDON 7/9 November 2024

The LIDC Congress 2024 will be held in London from 7 until 9 November 2024. 

We are glad to inform you that the questions to be discussed during the London congress are as follows :

  • Question A: What progress has been made, and is still to be made, in ensuring effective redress for harm resulting from infringements of competition law?

Background & Context:
It is generally accepted that private enforcement has an important role in increasing the effective functioning of competition regimes globally and that individuals and/or firms who suffer harm as a result of anti-competitive conduct should be entitled to compensation for their loss(es). Consequently, interest in, and the significance of, this aspect of the competition law ‘toolkit’ continues to grow.

There have been a number of initiatives in various jurisdictions to promote more private enforcement and provide the necessary legal and economic framework for this purpose. For example, in November 2014, the EU Damages Directive, which harmonised certain procedural rules for competition damages actions across all EU Member States (including the United Kingdom at the time) and sought to establish a level playing field across the EU, entered into force. Together with the 2013 Recommendation on Collective Redress, the Damages Directive was intended to make it easier for victims of anti-competitive conduct to obtain compensation.
During the past decade, the use of private enforcement of competition law has increased throughout Europe and beyond. However, the intensity and experience of private enforcement is very mixed. Some jurisdictions have considerable experience in dealing with damages actions, however, in others private actions are rare.

Major differences still exist among jurisdictions, even between the EU Member States. For example, in a number of Member States, there have not yet been any court rulings applying the provisions of the Damages Directive and, for temporal application reasons, many rulings are still based on pre-existing national law.

The 10th Anniversary of the EU Damages Directive provides the LIDC with an opportunity to take a critical look at how private enforcement has evolved around the world, taking stock of the progress that has been made and what obstacles remain, considering how these might be overcome to ensure: effective redress; and a balance between public and private enforcement.

National groups are invited to provide an account of the emerging practices and trends in private enforcement of competition law in their respective jurisdictions from a legal and economic perspective, reflecting on various factors such as: the relevant legal instruments; institutional developments; applicable jurisprudence; the relevant procedural, legal and economic framework; and key practical and litigation issues.

As announced previously, Andras M. Horvath has been appointed as International Rapporteur for Question A.

For those who have not already done so, we kindly invite you to designate your National Rapporteur for Question A and inform the LIDC as soon as possible and in any event no later than 15 December 2023.

  • Question B:  How should we approach copycat packaging ? 

Do registered designs file against copycats and on what legal basis (IP and/or Unfair Competition Law)?

International Rapporteur, Prof. Ilanah Fhima has agreed to be the International Rapporteur for Question B.

Background & Context:

It is often said that “imitation is the sincerest form of flattery”, however the proliferation of high-profile disputes in recent years concerning ‘copycat’ packaging, product names, and/or ‘look-alike’ product design suggests that brand owners view such practices less as a compliment and more as harmful to their businesses and misleading for consumers.

In some jurisdictions brand owners rely on unfair competition law to prevent competitors selling products in copycat packaging. In other jurisdictions, however, claims are based on one or more form of IP infringement (e.g. trade mark, registered design, and/or copyright infringement, and/or “passing off”).

Claims can be challenging from a legal, evidential and practical perspective. It also raises concerns as to whether there is a gap in the law or sufficient protection, as well questions about the potential impact of divergencies in approach and legal basis.

A key consideration is the risk of business being diverted from brand owners who have made significant investments and the potential market distortion. There are also questions of goodwill and brand reputation management. For retailers (and others using such packaging) there are concerns about (unwarranted) restriction of market access as a result of enforcement action. As regards consumer protection, there is also the question of whether consumers are truly being misled, or whether they are aware that they are purchasing a cheaper alternative product to the branded product/market leader, especially when faced with the current ‘cost of living crisis’.

With this in mind, and in order to identify any areas of divergence/convergence internationally, National groups are invited to provide an account of the existing legal framework, case-law, and emerging practices and trends concerning similar packaging in their respective jurisdictions and whether/how this seeks to strike the balance between recognising brand owners’ investment and interests, protecting consumers from confusion and ensuring fair market access for competing products.

Given recent and ongoing cases in the United Kingdom, across Europe and beyond, we expect that Question B will generate a lot of interest and lively debate and look forward to engaging with the National Chapters and individual members on this highly relevant topic.

Past Congresses

The last LIDC Congress was be held in Gothenburg (Sweden) on 21-24 September 2023.

The questions discussed were the followings:

Question A

Do recent developments in enforcement, case-law, and guidance from competition authorities and regulators make the delineation between legitimate and efficient purchasing and supply arrangements and infringing conduct sufficiently clear in practice that businesses and their advisors know how to stay on the right side of the law?

Question B

What mechanisms exist to avoid over-broad trademarks and address concerns that the trademark registers are clogged (e.g. bad faith in Sky v SkyKick; requirements for evidence of use), and are these mechanisms effective?

LIDC ad-Hoc Groups

The General Reporter and the deputy General Reporter may, when agreed by the President, set up ex officio an ad hoc Committee entrusted with studying and taking a formal position, on behalf of the League, on particular questions or evolutions of competition law or commercial practices. They are responsible for appointing the president of such Committee.

Any member of the League, who has made sure that at least two members from other groups will participate, may request the setting up of an ad hoc Committee. To this end, the member should send a draft proposal of the subject to the General Reporter. This member will become the president of the ad hoc Committee.

As soon as an ad hoc Committee has been instituted, the presidents of the national groups shall appoint one or two members of their group, representing the interests concerned, who will participate in the Committee’s works.

Information about the setting-up of an ad hoc Committee and progress of its work shall be given as soon as possible on the website of the League, where the final report of the Committee will also be published.

Any proposal of adoption of a position on behalf of the League shall be submitted, before it is published or advertised, for the approval of the President and the General Reporter, who will check that it is representative and, in case of conflicting views, make sure that all important opinions are expressed.

The President and the General Reporter shall decide upon the communication of the results of the ad hoc Committees’ work out from the League.

The ad Hoc Committees, created so far, drafted the following documents:
