How to plan successful IP mediation

How to plan successful IP mediation

Mediation offers several significant benefits to parties with Intellectual Property (IP) quarrels. It is often quicker and cheaper than litigation, is confidential, can resolve related conflicts in multiple jurisdictions and can lead to commercially focused solutions (which may not be available from the courts). When all parties engage in good faith, moderated talks can lead to a win-win situation, where old disagreements are settled and future business opportunities created. 
10 years on from the Brexit vote

10 years on from the Brexit vote

June 2026 marks the 10th anniversary of the United Kingdom's referendum on membership of the European Union. By a narrow majority, the country consented to end a period of harmonization that had begun in January 1973 with the then European Communities. Through an unheard-of withdrawal from the world's most sophisticated political and economic union, the Brexit vote has impacted many areas of law and policy over the past decade, including Intellectual Property (IP).
Transforming IP management: the shift from digital tools to intelligent systems

Transforming IP management: the shift from digital tools to intelligent systems

For many years, Intellectual Property (IP) software solutions have been built around a clear and necessary objective: bringing structure to complexity. IP portfolios can span multiple jurisdictions, legal frameworks and business priorities. They may include patents, trademarks, designs and a range of adjacent matters such as licenses, oppositions, agreements, domain names and other rights that require careful tracking and coordination. Managing this landscape demands precision and reliable visibility.
Everyday IP: Easter and the economics of commercial distinctiveness

Everyday IP: Easter and the economics of commercial distinctiveness

As a religious and cultural tradition, the symbols of Easter exist independently of corporate control; these beliefs, motifs and customs are living heritage, and the imagery associated with the holiday is free for all to use. No organization holds a monopoly on the concept of a spring rebirth, and no conglomerate owns a patent on the eponymous bunny.
The four main types of Intellectual Property: what they protect and why they matter

The four main types of Intellectual Property: what they protect and why they matter

Today, an organization's intangible assets can be worth considerably more than its cash, liquid financial holdings, equipment and real estate. As a result, the Intellectual Property (IP) rights covering everything from industrial manufacturing to digital entertainment constitute one of the pillars of modern commerce – and one of its currencies.

New dawn or damp squib? Mediation and arbitration at the UPC

he Patent Mediation and Arbitration Centre (PMAC) is an integral part of the Unified Patent Court (UPC). However, while the Court started operating in 2023 and received almost 1,000 cases in its first two years, the PMAC will only begin handling alternative dispute resolution (ADR) cases this year, with a formal opening ceremony to take place on June 2 in Ljubljana, Slovenia.
A new sense of self: Denmark's copyright amendment against deepfakes

A new sense of self: Denmark's copyright amendment against deepfakes

We have all seen or read about examples of media created by generative artificial intelligence (GenAI): synthesized images, videos and audio that appear to represent real people or famous characters. From the benign to the blameworthy and every conceivable shade in between, this rising phenomenon has only just begun to make its cultural presence felt.
University IP and the role of AI in technology transfer

University IP and the role of AI in technology transfer

Universities generate innovations that can transform industries and society. Yet most Intellectual Property (IP) produced never reaches the market, with 70 to 80 percent of university patents remaining unlicensed. Bridging this gap between discovery and impact is the central mission of technology transfer offices (TTOs), which face the ongoing challenge of converting discoveries into actionable opportunities. In this context, artificial intelligence (AI) has emerged as a powerful enabler, helping teams manage large-scale analysis and highlighting where expert attention is most needed, without replacing humans.
