Walid Chaiehloudj Pay for delay agreements: An overview of EU and US Case Law


Are pay-for-delay agreements still a hot topic for competition authorities and courts? The answer, albeit reckless, is definitely “yes”. As the years go by, competition authorities still seem determined to fight these agreements, which are sometimes referred to as “patent settlements” or “reverse payment settlements”. Fundamentally, there are several reasons why competition authorities on both sides of the Atlantic remain vigilant.

Walid Chaiehloudj USA: The Federal Trade Commission waives its right to ask the Supreme Court to rule on a monopolization practice involving intellectual property rights (Qualcomm)


Short justifications and a great deal of disappointment is the feeling generated by the FTC’s questionable choice to drop the Qualcomm case from the US Supreme Court. It is true that the case was a sensitive one and that the FTC’s arguments had been curtly rejected by the Ninth Circuit Court of (...)

David va-t-il renverser Goliath ? Un tel exploit, certes rare à l’échelle de l’histoire, n’est pas tout à fait inédit. La prouesse de David, enfermée dans le saint livre qu’est la Bible hébraïque, n’a d’ailleurs pas échappé aux éditeurs de presse américains. Ces derniers, semblant se souvenir de l’exploit du (...)

Walid Chaiehloudj USA: The Court of Appeals for the Seventh Circuit applies the Noerr-Pennington doctrine in an antitrust case on the futures market (U.S. Futures exchange / Board of Trade of the City of Chicago)


Anti-trust law, whose provisions are of public order, belongs to a matter imbued with imperative nature. It is therefore very difficult for companies to escape its grasp when the loops of Section 1 or Section 2 of the Sherman Act close around them. At most, they can try to use the residency (...)

Walid Chaiehloudj USA: Eighty-two academics file an amicus brief with the Fifth Circuit Court of Appeals in support of the Federal Trade Commission’s position in a pay-for-delay case (Impax Laboratories)


The Impax case that we have recently discussed in these columns has bounced back in the courts (Concurrences No. 2-2019, Art. No. 90540, p. 208). The pharmaceutical company seeks to challenge the Federal Trade Commission’s (FTC) assessment that the agreements entered into by the company were (...)

Walid Chaiehloudj USA: The Northern District Court of Georgia receives a complaint filed by an online advertising company accusing a well-known search engine company of monopolizing the market (Inform / Google, Alphabet, Youtube)


Is the antitrust vise around Google tightening in the United States? A previous chronicle might have raised doubts about this (Concurrences No. 3-2019, art. No. 91291, p. 211). We remember that in Google vs Marshall’s Locksmith Service, the search engine had finally managed to escape antitrust (...)

Since the Supreme Court’s 1985 decision in Mitsubishi Motors Corp. v. Soler Chrysler-Plymouth, 473 U.S. 614 (1985), the question of whether antitrust law and arbitration form an impossible couple no longer arises. The decision had clearly answered this question by stating, inter alia, that "once (...)

Walid Chaiehloudj US: The Court of Appeal for the District of Columbia Circuit confirms that search engines, leaders in the online search market, benefit from an antitrust immunity (Google / Marshall’s Locksmith Service)


Can a search engine escape antitrust prosecution when it acts as an intermediary on the Internet by providing false information on the location of companies? In other words, can the Sherman Act be overridden when a search engine merely takes over location information provided by third party (...)

Walid Chaiehloudj United States: The U.S. Court of Appeals for the Ninth Circuit denies a challenge to the use of the per se rule in a criminal antitrust case (USA / Javier Sanchez)


Inexistent at the level of the European Union and very little used in France, criminal antitrust law seems to be ignored on the old continent. This is not the case in the United States. On the contrary, it enjoys a remarkable influence on the other side of the Atlantic. For several decades now, (...)

The case recently decided by the court of the Eastern District of Virginia is interesting for several reasons. In particular, it reveals the very high antitrust risks that certain companies that result from a merger approved by the Department of Justice may face. In this case, after the U.S. (...)

Walid Chaiehloudj United States: The US Supreme Court rules that the credit card market is a multisided market and that anti-steering clauses do not have anticompetitive effects on this market (American Express)


The Amex case is certainly one of the most emblematic cases of 2018 in the United States. It took root in the fall of 2010 following a complaint filed jointly by the Department of Justice and seventeen states against three bank card companies (EECB): Visa, MasterCard and American Express (...)

By imposing the rule of reason on lower courts to review entry deferral agreements, the Actavis judgment did not resolve all the difficulties posed by pay-for-delay ( Federal Trade Commission v. Actavis, 133 S. Ct 2223, 2013, obs. J.-C. Roda). Indeed, the choice of the rule of reason has not (...)
