The right response to infringement

Focused action across IP types

  • Counterfeit goods, or "fakes," pose serious risks for manufacturers and retailers alike, not least because the more recognized a brand becomes, the more likely it is to be targeted. Beyond lost revenue, imitations can erode customer trust and weaken a brand's distinctiveness.

    With offices across key jurisdictions and a coordinated enforcement network, Dennemeyer helps companies track down and act against major counterfeiters, resolving multi-jurisdictional branding issues through a single, trusted partner.

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.

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.

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.

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.

Breaking the silos: untangling Intellectual Property services in a connected era

Specialization, at its best, brings depth of understanding and quickness of action. At its worst, tunnel vision sets in and outreach with experts in other fields is quashed. This is when professional hubs become silos; shuttered off from colleagues and partners, the difficulty of moving information in or out of these knowledge repositories undermines much of the contribution their expertise brings.

Ice cream innovations: IP with a cherry on top

Whether you are a fan of rocky road or classic vanilla, nothing says contentment like a melting scoop of ice cream. While most of us stay focused on dodging drips, we rarely consider the patents and trademarks that brought our go-to flavors to fruition. Behind that creamy, dreamy dessert lies a rich swirl of Intellectual Property (IP) – the kind that has shaped how frozen favorites are developed, delivered, sold and enjoyed.

Revisiting INTA 2025

The yearly coming together of practitioners and thought leaders at INTA is as close to an industry touchstone for trademarks as can be imagined, for it helps to define the zeitgeist by expressing and discussing the many influences behind the moment. Whether commercial, creative, legal or ethical, these topics are tokens of prior trends and indicators of possible trajectories for brand protection. Thus, the ideas shared at INTA continue to shape the nature of the Intellectual Property (IP) sector long after the banners have been packed away.

When the warm weather rolls in, the call of the backyard feast is almost irresistible.
