18 The applicant may, however, exclude such part or parts of the design provided that the parts submitted are sufficient to identify the layout design and its function. The Patent Office shall maintain a register in which it shall record all applications according to the rules and procedure prescribed by the Regulations. Each application shall be subject to the payment of fees, as determined in the Regulations, not exceeding 1,000 pounds. The application shall not be accepted if it is filed after two years from the date of its first commercial exploitation, within or outside Egypt, by the owner of the right.

(2) Personal use or for the purpose of test, examination, analysis, teaching, training or scientific research of the protected layout design. Where such use leads to the creation of a new layout design, the creator shall be entitled to have it protected. (3) Creation of a layout design, identical with another protected layout design, as a result of independent efforts.
