Prof. Valerio Sterzi: The problem with patents

Valerio Sterzi, associate professor (Maître de conférences, HDR) in Economics at University of Bordeaux

 

Valerio Sterzi is on a mission. Ever since his undergraduate days at Bocconi University in Milan, he has been fascinated by the economics of innovation. At first he had great faith in patents as a tool for fostering innovation.

 

But as he delved ever deeper into the world of innovation economics - through his master at Pompeu Fabra University, Barcelona, and then a doctorate at Bergamo University in Milan – he started to see problems.

 

Part of the problem was that patents were a topic mainly studied by legal academics, not economists. “I wanted to correct this,” Professor Sterzi said in an interview.

 

“There needs to be more exchange and interaction between economists and law academics. Without the input of empirical economic evidence the debate about the role of patents is rather abstract. I want to get away from that,” he said.

 

Sterzi has just released a new study into the secondary market for patents in Europe, showing that non-practising entities (NPEs) appear as current owners of almost 20K patent applications at the European Patent Office (EPO).

 

The study provides further evidence of the significant presence of NPEs in Europe. NPEs target mainly the ICT industry, where they acquired almost one in ten of all transacted patents over the past decade, with a peak of over 25% in 2019.

 

Last year Sterzi published an in-depth study of an aggressive NPE (also known as a patent assertion entity (PAE) or more colloquially, patent troll). It read like a detective story, following one dormant shell company after another to identify the true owners.

 

Sterzi’s latest study does not focus specifically on patent abuse. That will again be the main focus of his follow-up study expected in 2022. Instead this paper looks to quantify the presence of NPEs in the European patent market and to characterize their business models.

 

What is clear from this study is that the NPEs acquiring almost 10% of ICT patents traded in Europe include big established firms, many based in the US, as well as the small shell companies identified last year. “It’s not a question of size, it’s a question of intention,” Sterzi said.

 

The study’s findings also show that the majority of NPEs operating in Europe have business models built around monetizing their patents, rather than using them to make innovative products.

 

When an NPE acquires a patent, the number of citations of that patent falls when the acquirers are large patent aggregators. This indicates that the patented idea was of limited use, and that its owner wasn’t actively exploiting the patent in the market.

The number of citations is important because it indicates how relevant the patented idea is. Patents with limited citations are often used for financial gain only, and do not contribute much to further innovation.

 

Poor quality patents are ideal for NPEs looking to make money through litigation, rather than through exploitation of the patented technology. First, they are cheaper to buy. But more important, they are just as effective a tool to threaten companies that the NPE claims are breaching its patents.

 

To an operating company, the potential harm from an injunction, and the likelihood of a protracted and costly legal battle, may be as great with a trivial, low quality patent as with a higher quality one. So an operating company may  settle out of court to avoid these risks in either situation.

 

“I can’t say all NPEs are bad – some do encourage innovation by renumerating inventors – but there is a strong heterogeneity in the business models of NPEs – one focussed on monetization rather than intermediation,” 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.
