Custos IPC

The cooperative for self-employed patent attorneys

In our cooperative Custos IPC, independent patent attorneys, each with their own specialism, work together under one banner. This collaboration allows you, as an affiliated attorney, to do what you are good at and continue to grow in it.

We provide a stimulating and supportive environment where collaboration, collegiality and knowledge sharing are central. We take the operational and administrative burdens off your shoulders, allowing you to focus entirely on delivering high-quality service to your clients.

A cooperative that works — for you and your clients

The cooperative model has been chosen deliberately: it combines the freedom of independent entrepreneurship with the strength of a professional organisation. As a member, you benefit from:

  • a close-knit and collegial network of experienced fellow patent attorneys;
  • shared knowledge and high-level substantive sparring;
  • commercial support and active acquisition for new work opportunities;
  • professional formalities and back-office support;
  • a strong brand that stands for quality, transparency and reliability.

We can work together, reinforce one another, and jointly handle complex IP issues and larger portfolios.

The cooperative also offers advantages for clients. They work with intrinsically motivated freelancers, without the vulnerability of a solo operator. 

"By working at Custos, I learn more than I ever thought I would; I see up close how others draft patent claims, I see how others acquire new clients, I see how others advise clients, and that makes me sharp (again)."
"The main reason for being affiliated to Custos is continuity. If I break both wrists, patent applications can still be delivered on time, and no deadlines are missed."
"A peer review is a standard part at Custos when you write an application. With a short review of the conclusions by a colleague, you can often dot some i's and cross some t's. It is important for quality and this way you learn from each other."
"Did I mention it's very cosy?"
