Is a clinical trial a legimate reason for the non-use of a trademark?
The introduction of a new product may be a long-term project, especially for a pharmaceutical preparation. R&D and the approval of such a new product take a lot of time. In parallel with the R&D efforts, a trademark has to be developed and registered. Timing is of the essence, because within 5 years of registration, actual use of the trademark becomes mandatory and without use the newly obtained trademark rights become vulnerable.
