《与朱元思书》中概括富春江美景的句子是：，。 答案：【1】奇山异水【2】天下独绝 A patent is the tool that can be used to prevent people from making, selling, offering to sell or importing the patented items without permission. According to the patent law, any person who “invents any new and useful process, machine, or composition (成分) of matter, or any new and useful improvement may obtain a patent.” The law has described the limits of the field of subject matter that can be patented, and thus it has been held that the laws of nature, physical phenomena, and abstract ideas are not patentable subject matter. A patent cannot be obtained upon just an idea or suggestion. In order for an invention to be patentable it must be new as described in the patent law, which also states that an invention cannot be patented if: “(a) the invention was known or used by others in this country”, or “(b)the invention was patented or described in a printed publication in this or a foreign country”, (c) the invention was in public use or on sale in this country more than one year before the application for patent”. Moreover, even if the subject matter sought to be patented is not exactly shown by the previous art, and involves one or more differences over the most nearly similar thing already known, a patent may still be refused. The subject matter sought to be patented must be fully different from what has been used or described before in the area of technology related to the invention. For example, the substitutions of one color for another, or changes in size, are not patentable. 56.
