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.


We are pleased to announce that the next LIDC Congress will be held in Gothenburg (Sweden) on 21-24 September 2023.

Gothenburg Congress on 21-24 September 2023 – Question A and B – Flyer

The questions that will be discussed are 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?


We are seeing consumer prices rising at pace globally, central banks have increased rates, and events such as the Covid pandemic, the war in Ukraine, and Brexit continue to stress supply chains. 

Against this backdrop, it is important that companies are able to distinguish clearly between legitimate and efficient conduct and infringements of the applicable rules and to assess the impact on their commercial relationships.

In addition to focusing on sellers and the conditions on which they sell their products or services to buyers, buyers’ conduct in their interactions with suppliers and markets when purchasing goods and services has recently come under increased scrutiny from competition law, enforcement and guidance (e.g. the Horizontal Guidelines).  

From co-ordinated conduct by buyers, such as joint purchasing/buying alliances (e.g. rules for purchasing alliances in the food retail sector in France), buyers’ cartels and purchase price fixing (e.g. the Ethylene and Car Battery Recycling cases), to unilateral conduct by buyers that hold substantial purchasing power. As regards the latter, new rules and cases (e.g. in Belgium) have considered the “abuse of economic dependence”, which targets situations where a company abuses the relative economic dependence of another company (supplier or customer).

Different jurisdictions have taken a range of approaches, which have evolved and changed over time. What is the current situation in these jurisdictions and what are the LIDC National Chapters’ and members’ respective experiences – is the line between legitimate and infringing conduct sufficiently clear or is further guidance from authorities and courts required?


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?


Trademark owners understandably want to protect as widely as possible around their brand. However, this can lead to cluttered trademark registers which increase the cost (deadweight loss) of launching a new brand, and may restrict dynamic competition particularly from smaller players.

Different jurisdictions have taken a range of approaches, which have evolved and changed over time: from requirements of use (and/or evidence of use) to potential revocation for non-use; from requirements of filing by class and limiting scope within class to requirements that filings are not made in bad faith. For example, bad faith has been an issue in recent cases (from Hasbro through Sky v SkyKick which still pending in the English courts).

What are the LIDC National Chapters’ and members’ respective experiences in the effectiveness of these mechanisms, or other rules and practices, in seeking to allow the ‘right’ scope of protection?

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:
