The Patent Battle Behind the Senseo: A Lesson Brewed in Friesland

A few weeks ago, we were on a weekend getaway in Friesland, a quiet northern region of the Netherlands. Over breakfast in a cozy Douwe Egberts café in Leeuwarden (see the image at the top of this page) we were reminded of just how deeply rooted Dutch innovation can be. Douwe Egberts (DE), founded in 1753 in the Frisian town (or rather village) of Joure, is one of the country's most iconic coffee brands. And in that same café, with the smell of fresh coffee in the air, I couldn't help but think of one of DE's most ambitious innovations: the Senseo coffee system, developed together with another Dutch giant: Philips.

The Senseo Story

Launched in 2001, Senseo revolutionized home coffee making in Europe. Instead of traditional filter coffee or full espresso machines, users could now brew a single cup in seconds, using convenient, pre-packed coffee pads. It was a sleek, affordable, and consumer-friendly alternative (hmmmm, I won't mention the taste of the coffee from those early machines....), and a great example of a strategy where large corporations team up to scale a new technology into a dominant market solution.

Philips and DE: A Dutch Innovation Duo

Philips brought its technical expertise and appliance design; DE brought the brand, the beans, and the consumer base. Together, they captured the European market, especially in the Netherlands, Belgium, Germany, and France. But success invites competition, and soon other manufacturers began producing similar pads for use in Senseo machines.

The Patent Trouble

Sara Lee, then owner of Douwe Egberts, filed a European patent to protect the Senseo coffee pads (patent number EP0904717B1). The idea was simple: if others couldn't legally make compatible pads, DE could preserve its market advantage. But that strategy backfired. In 2006, the European Patent Office revoked the patent, declaring it lacked novelty and inventiveness. Coffee pads, the court found, already existed—and the specific form used by Senseo wasn't different enough to qualify as a true invention.

A Teachable Moment

This case is often cited as a cautionary tale in IP strategy. Even major companies can make patent decisions that don't hold up in court. In hindsight, Philips and DE might have been better off focusing on branding and market positioning than trying to patent something not truly patentable.

Want to understand why that patent didn't stick? A patent all comes down to three key requirements:

  • Novelty (is it new?)
  • Inventive Step (is it non-obvious?)
  • Industrial Applicability (can it be used in industry?)

We explain these principles in detail on our How to Get a Patent page—along with advice on when NOT to patent something, which is just as important.

Conclusion

Sitting in that DE café in Friesland, sipping coffee where it all began, I was reminded that innovation is rarely just about invention. It's about timing, strategy—and sometimes knowing when to let go of the idea of a patent. Senseo succeeded anyway, but the legal lessons it brewed are still worth learning.
