Employee invention remuneration ends on declaration date, not patent grant date, per Polish Patent Act.

The Supreme Court ruled that employees are entitled to remuneration for their invention up to the date the employer declares it will not seek a patent. The court found the invention was used and generated benefits before the employer's declaration, rendering the patent grant date irrelevant for calculating compensation. Consequently, the legal rule established is that the declaration date, not the patent grant date, terminates the right to remuneration for employee inventions.
