Abstract: Protection of patents is of the regional character. To boost the patent value, Research Institute of Natural Gas Technology of PetroChina Southwest Oil & Gasfield Company carried out the strategy for distribution of key patents both as home and abroad and strengthened patent protection and utilization. Distribution in the patent-applying nation should take into account three dimensions – protection, stockpiling and confrontation. It is necessary to give priority to the nations radiated by distribution of overseas market. Then the nations with the market to be opened will be selected. Finally, it is necessary to consider the main business areas of competitors. Research Institute of Natural Gas Technology analyzed and summarized the technological advantages in the areas of chemicals for oil and gas field development, corrosion evaluation and control, natural gas purification and utilization, and natural gas measurement, and strengthened patent distribution of the relative products as well as standardized inspection technology and devices. Based on technological benchmarking and determination of the key invention points, the research institute selected some key technologies to form the key high-value patents. As for overseas patent distribution for two items of technology – amine reactivation technology and gas chromatography separation technology, the research institute analyzed the technological advantages, determined the key patents, overseas markets and patent-applying nations, improved the quality of patent text, distributed the patents indispensable for international standards, and strengthened construction of technology, patent and standard interaction system for innovation, thus helping the enterprises with their high-quality development.

摘要： 专利保护具有地域性，为了提升专利价值，中国石油西南油气田公司天然气研究院实施核心专利国内外布局策略，加强专利保护和运用。专利申请国布局中，从保护性、储备性和对抗性3个维度考虑，优先布局海外市场辐射到的国家，其次选择待开拓市场的国家，之后考虑竞争对手的主要营业地。天然气研究院梳理了油气田开发化学、腐蚀评价与控制、天然气净化与利用、天然气计量等领域的技术优势，加强相关产品、标准化检测技术及装置的专利布局。通过技术对标和确定核心发明点，遴选先进的核心技术形成高价值核心专利。在胺液复活技术、气相色谱分离技术两项国外专利布局中，分析技术优势，确定核心专利、海外市场、专利申请国，提升专利文本质量，布局国际标准必要专利，加强技术、专利、标准联动创新体系构建，助力企业高质量发展。
