D
- Description
- Part of the application disclosing the invention sufficiently for a skilled person to carry it out.
- Designation
- Mechanism by which a patent application indicates the states or regional systems in which protection may be obtained. Under the current PCT and EPO procedures, the contracting states concerned are in principle designated automatically on filing. A designation only reserves the possibility of protection: it is neither a grant, nor entry into the national or regional phase, nor the completion of the later formalities required in each country. A designation may in some cases be withdrawn. A designation reserves a territory during the application procedure.
