Jeśli kogoś to jeszcze interesuje to poniżej kilka faktów (dla USA, ale generalnie jest podobnie) myślę że wątpliwości będą rozwiane. Poniższe nie zmienia faktu ochrony CG przez prawa TM. Pozdrowienia dla Moda. Za Wiki: "In the United States, for utility patents filed on or after June 8, 1995, the term of the patent is 20 years from the earliest filing date of the application on which the patent was granted and any prior U.S. or Patent Cooperation Treaty (PCT) applications from which the patent claims priority (excluding provisional applications). For patents filed prior to June 8, 1995, the term of patent is either 20 years from the earliest filing date as above or 17 years from the issue date, whichever is longer. Extensions may be had for certain administrative delays."
