单选题Dreams Dreams do not happen when you're asleep. They happen when you're awake. Whatever your goals are, always remember you can make it true. Whether it be love, money, a childhood dream, and ultimately happiness, the most important idea is that you must never lose sight of your dream. Create reminders. Think about your original motivation often. Besides obvious factors that will come along when your dream is realized, think about other reasons. Who are you doing this dream for? Remind yourself often of your plan. Physical symbols always help—posting up pictures of the end result, buying items that symbolize your goals. Express your dream frequently. Whisper your dream through moonlight. Shout it on a busy highway. Write it on a balloon and set it free. Write it on paper boats and float them in the ocean. Write it as a message on a bottle and float that into the ocean. Explore and try different ways of different cultures of making ishes come true, small or big: paper cranes, and shooting stars. Tell your pet if you have one. Tell it to all the people you care about in your life. Create deadlines and punishments. For every step along the way, think of a realistic deadline. If too small, eventually you will be crashed with all the work you need and possibly never do it. If too large, you will probably forget about it. Punishments are necessary. They can be keeping yourself away from your favorite activities. Get a friend or family member to enforce this punishment. Keep your life. Do not forget about friends, family, work, and especially yourself! Keep contact with friends and family: over the internet, visit them, write to them. Try not start skipping work to work on your dream. Keep your brain, body, and soul in good shape at all times. Sleep often, read often, and enjoy life. Brainstorm ideas for your dream. Mind mapping (essentially creative concept mapping) is the ideal way to brainstorm. Any creative outlet will do just fine to find some creative ideas for your dream, especially writing or drawing. Any sort of art, even singing, playing music, photography, wood-carving can work. Buy a journal or two. Find inspiration.In order to make your dream come true, you have to forget about friends, family, work, and especially yourself.（）ATrueBFalseCNot Given
问答题甲公司指派员工唐某从事新型灯具的研制开发，唐某于1999年3月完成了一种新型灯具的开发。甲公司对该灯具的技术采取了保密措施，并于2000年5月19日申请发明专利。2001年12月1日，国家专利局公布该发明专利申请，并于2002年8月9日授予甲公司专利权。此前，甲公司与乙公司于2000年7月签订专利实施许可合同，约定乙公司使用该灯具专利技术4年，每年许可使用费10万元。 2004年3月，甲公司欲以80万元将该专利技术转让给丙公司。唐某、乙公司也想以同等条件购买该专利技术。最终甲公司将该专利出让给了唐某。唐某购得专利后，拟以该灯具专利作价80万元作为出资，设立一家注册资本为300万元的有限责任公司。 2004年12月，有人向专利复审委员会申请宣告该专利无效，理由是丁公司已于1999年12月20日开始生产相同的灯具并在市场上销售，该发明不具有新颖性。经查，丁公司在获悉甲公司开发出新型灯具后，以不正当手段获取了甲公司的有关技术资料并一直在生产、销售该新型灯具。唐某作为发明人，依法应享有哪些权利？
