How to understand the cost of a patent application?

The costs of a patent application depend on your specific situation and objectives. That is why at Custos IPC we offer a free initial consultation, in which we discuss your idea and prepare a substantiated cost estimate.

In doing so, we provide clear insight into what costs are incurred at what point: from the initial patentability analysis to the final patent grant. We also discuss any tax advantages, such as the innovation box, which can significantly reduce the net cost of a patent.

Feel free to contact us for an informal discussion. We will be happy to think with you about a realistic and well-founded business case for your patent investment.
