Patent data

As usual in patent statistics, so-called fractional counting was applied at the level of patent families: — A patent family summarises all patent applications belonging to the same invention (e.g. an invention can be filed at different patent offices — in such a case only 1 patent is counted). — If a patent is filed by several organisations/persons located in different regions, the patent is counted pro rata by region, i.e. weighted by the factor (number of applicants from the region)/(number of different applicants). For example, if a patent has four applicants, 3 of which are located in the MRN and 1 outside the MRN, the patent with the value 0.75 enters the evaluation for the MRN. — The evaluation by technology fields is carried out via the IPC classes assigned to a patent. Patents can obtain a large number of different IPC classes and can therefore be assigned to several technology fields. If a patent has several technology fields, the number of patent applications per field is weighted by factor 1/(number of different technology fields). This means that the sum of patent applications per technology field corresponds to the total number of patent applications在专利统计领域，遵循常规操作，本次分析在专利家族（patent family）层面采用了所谓的分数计数法： — 专利家族指归属于同一发明的所有专利申请的集合（例如，一项发明可向不同专利机构提交申请，此种情形下仅计为1件专利）。 — 若一项专利由位于不同地区的多个机构或个人共同提交，则按地区进行比例计数，即通过（该地区申请人数量）/（总不同申请人数量）的权重因子进行加权。举例而言，若某件专利共有4名申请人，其中3名位于MRN地区，1名位于MRN地区之外，则该专利将以0.75的权重计入MRN地区的统计评估。 — 技术领域维度的统计评估通过赋予专利的国际专利分类（International Patent Classification, IPC）类号开展。一件专利可被赋予多个不同的IPC类号，因此可被归入多个技术领域。若某件专利涉及多个技术领域，则每个技术领域对应的专利申请数量将以1/（不同技术领域总数）的因子进行加权。这意味着各技术领域的专利申请数量之和与总专利申请数量保持一致。
