Get in touch with Loek
Do you have a question about your invention, or do you want to discuss whether a patent in Europe makes sense? Call me or use the form. You get a personal reply from me.
Would you rather talk it through? Ask for a strategy call in your message and I will propose a few times for a phone or video call. I am based in the Netherlands, on Central European Time.

Questions about contacting a European patent attorney
Through the form or by phone. Send a few lines about your situation and you will hear back from me personally, because I read and answer everything that reaches Patents4Business myself. If you would rather talk, ask for a strategy call by phone or video and I will suggest a few times.
Yes, on +31 6 12147641. I work from the Netherlands, on Central European Time, so a morning call from the US East Coast reaches me in the afternoon. If I cannot pick up, send your question through the form and I will call you back at a time that suits you.
A few sentences about what you have developed, in which field and what you want to achieve with it are enough. Technical details, drawings or test data can wait until the strategy call. If there is a deadline, such as a trade show, a publication or the end of your 12-month priority period, mention it right away.
Take the time to discuss your invention
For a short question, the form or a phone call is easiest. If you want to go through your invention and your business goals in depth, a strategy call is the better route.
