Compad Consulting and Werner & Mertz litigating over entitlement to a patent

Reading time: 2 minutes

As reported by Christopher GILB in the Luzerner Zeitung today, there is some litigation going on at the FPC about entitlement to a European patent pertaining to a washing agent that is free from palm oil.

Where’s the patent?

It appears that Werner & Mertz (well known e.g. for its brands Erdal® and Frosch®) has sued the Swiss start-up company Good Soaps for lack of entitlement to the patent, i.e. unlawful usurpation thereof.

The patent has not been identified in the news. I could not leave it at that and did my homework. The patent application at stake is EP 2 592 134 »; the currently registered applicant is Compad Consulting GmbH. See the European Patent Register for further information. The file wrapper is telling: The complaint of 9 January 2019, the reply of 20 September 2019 (including all appendices) as well as the comments on the rejoinder of 5 December 2019 are available online. The instruction hearing took place on 8 July 2019 — without a settlement being reached.

The main hearing is said to be scheduled for 16 September 2020. I trust this will get interesting …

UPDATE 19 August 2020:

The official announcement of the main hearing has just been published by the FPC. No surprises anymore, it’s indeed all about EP 2 592 134 ».
