Prof. Sikorski’s latest paper: IPRED needs targeted reforms to strengthen the principle of proportionality in patent litigation

There is broad agreement on the need for taking proportionality considerations into account in patent litigation cases but it’s not being applied in the courts in Europe. As a result, injunctions are being handed out automatically in almost all cases, even though EU legislation – the IP Rights Enforcement Directive (IPRED) – specifically calls for judges to apply proportionality.

IPRED needs targeted amendments in order to correct this. In his paper titled Permanent Injunctions and the Reception of the Principle of Proportionality in the European Union, Rafal Sikorski, assistant professor, Chair of European Law at the Adam Mickiewicz University of Poznan in Poland, calls for reform of the directive.

“The EU should consider introducing a set of factors to IPRED that the courts should consider when applying proportionality. In fact, this approach has already been taken by the EU legislator in the Trade Secrets Directive,” Professor Sikorski said in an interview.

He proposes that a number of factors - similar to those in the Trade Secrets Directive - should be taken into consideration before granting injunctive relief. First, courts should consider that non-practising entities, also known as patent assertion entities or more colloquially as ‘patent trolls’, often exploit patents purely for monetary gain that can be obtained through the enforcement system rather than for their inventive value. Judges need to be aware of the fact that such patentees seek injunctions primarily to obtain excessive royalties.

Courts should also bear in mind whether a patent owner knowingly tolerated the alleged patent infringement for some time before acting to defend their rights, as this would imply that injunctive relief is only sought to extract disproportionate settlements.

Third, courts should also look to the nature of the patented invention. This is important especially in cases involving single patents in complex multi-functional products like cars or smart phones. A patent protecting a relatively minor invention on one of many functionalities implemented in those types of products should not give a right holder power over the entire  product.

Third-party interests are taken into consideration in the US. They have also been considered by UK courts. For example, injunctions have been denied in a Microsoft Windows case where a patent protected a security feature. There, the court said that an injunction risked endangering the security of data of millions of users.

Another example involved a US court denying an injunction in a case involving a patented invention implemented in Toyota cars. There, the injunction would have affected the business operations not only of the manufacturer but also of multiple car dealers. 

“Courts should be moving in this direction in the EU too,” professor Sikorski said. “It’s important to be crystal clear on this, as the UPC gets going and starts developing its jurisprudence. Failure to act now will make it harder to implement proportionality at a later stage. It’s time for the EU to act now – make it clear that proportionality is something courts have to take onboard. Otherwise, the UPC will become excessively imbalanced,” he said.

Adding such a set of factors to IPRED would provide guidance for the courts. “It could assist them in applying proportionality when deciding whether to grant, tailor or deny an injunction. It would also provide much more certainty to the market participants - both the patentees and the patent implementers,” professor Sikorski said.

At the same time, he said it is important to demonstrate that patent rights are not being devalued, he said. “There is a role for injunctions but before granting them, courts should first consider the proportionality option. I’m not proposing anarchy. Rather, by introducing a set of factors, I aim at greater predictability as to how proportionality might be applied,” he said.

And by making the system more predictable, it will make it harder for so-called patent trolls to make opportunistic attacks on those implementing patented inventions.  “It’s a question of tempering absolute rights, while protecting the innovation process,” he said.

IP2Innovate response to the Commission’s Call for Evidence on the Digital Fitness Check

IP2Innovate welcomes the Commission’s Digital Fitness Check and its commitment to delivering a simpler, more competitive Europe. As a coalition of small and large companies that create innovative products and services in Europe and that collectively hold thousands of European patents, IP2Innovate strongly supports efforts to reduce unnecessary regulatory burdens for companies while maintaining high standards of protection for fundamental rights, consumer safety and European values. A key obstacle to Europe’s digital competitiveness lies in the outdated framework governing the enforcement of patents. The Intellectual Property Rights Enforcement Directive (IPRED), adopted in 2004, requires remedies for patent infringement to be proportionate but does not set out clear criteria for how proportionality should be assessed in relation to today’s complex digital and connected technologies – such as AI systems, IoT devices, semiconductors, smart vehicles or critical infrastructure. As a result, the lack of clear rules on how to ensure remedies are proportionate in relation to complex products has led to the de facto automatic granting of injunctions in patent cases, which result in the removal of entire product lines from the market even when the patent infringement relates to a minor feature of a complex product that incorporates thousands of patented components1. For complex products automatic injunctions create excessive litigation risk, legal uncertainty and significant disruption to supply chains, investment and innovation, and force Europe’s digital innovators to pay excessively high licensing fees for patents to settle patent lawsuits. This situation is to the detriment of Europe’s industrial base and competitiveness. Modernising IPRED to clarify how courts should assess proportionality and consider alternative remedies where appropriate would directly support the Commission’s simplification agenda. While this would require targeted amendments to the IPRED, the overall effect would be a reduction in regulatory burdens through: • Reduced litigation risk and administrative burden, particularly for SMEs and companies developing complex digital products; • Improved legal certainty and predictability, enabling companies to invest with confidence; • Lower financial and operational disruption, safeguarding innovation, jobs and supply chains. Amending the IPRED to provide further specificity on proportionality in patent litigation would not impact a patent holder’s ability to enforce its patent rights, but would make sure such enforcement is appropriately balanced in the digital age. Additionally, amending the IPRED would help reduce the number of avoidable court cases by making appropriate settlements between patent owners and innovative product companies more likely. As a result, courts would face a lower workload and could handle the remaining cases more efficiently, ultimately strengthening trust in the European patent system. A clearer, more balanced framework would align Europe with other regions of the world, enhance Europe’s global competitiveness, and prevent distortive practices that extract value without contributing to innovation. This issue is particularly well‑suited to be addressed at EU level, as digital products and services circulate seamlessly across the entire Single Market. Divergent interpretations of IPRED’s proportionality requirement create fragmentation, legal uncertainty and opportunities for forum‑shopping. Because patent enforcement rules directly affect the functioning of the Single Market, action by individual Member States cannot entirely resolve these inconsistencies. Only EU‑level reform can ensure uniformity and promote a proportionate and consistent application of remedies across jurisdictions. Modernising IPRED therefore directly supports the Commission’s objective of “a more cost-effective and innovation-friendly implementation of European rules – all the while maintaining high standards and core objectives of the rules”. This is exactly what IP2Innovate is calling for with the modernisation of the IPRED to clarify how courts should assess proportionality and consider alternative remedies where appropriate. Experience shows that non-binding clarification is not sufficient to address this structural problem. The Commission’s 2017 guidance on IPRED did not materially change judicial practice or reduce the near-automatic granting of injunctions in patent cases. More than two decades after its adoption, IPRED requires targeted modernisation to ensure that Europe’s patent enforcement system supports – rather than hinders – the Union’s objectives of competitiveness, simplification and technological leadership. About IP2Innovate IP2Innovate is a coalition of small and large research-intensive companies that develop innovative products and services in Europe, collectively holding thousands of European patents, as well as industry associations representing more than 40 companies. The coalition works with policymakers, the legal profession and judicial authorities to promote a balanced and innovation-friendly European patent system that supports investment, competitiveness and the successful commercialisation of new technologies in Europe. 1.
