This dataset is constructed by collecting data including patent applicants, legal status, technical subject classification, number of simple patent family members and other relevant data in the reverse osmosis membrane field. It primarily covers invention patents and utility model patents related to reverse osmosis membranes sourced from the global patent database. The keyword "reverse osmosis membrane" is used to screen patent data focused on reverse osmosis membranes from the retrieved results, and the patent data is evaluated and classified via a self-developed algorithm. This dataset can be utilized to understand the changes in reverse osmosis membrane patent data, and facilitate the mastery of intellectual property work achievements in the reverse osmosis membrane field; By comparing the reverse osmosis membrane patent data of different enterprises and individuals, it is possible to analyze the technological innovation capabilities and differences in innovation levels of each entity; Understanding the technological development trends of reverse osmosis membranes helps enterprises avoid redundant R&D and prevent their developed technologies from infringing others' intellectual property rights.

1. Data Source: Data of invention patents and utility model patents related to reverse osmosis membranes from the global patent database;

2. Data Collection: The target layer of this dataset is patent technological relevance. The indicator layer divides the indicator system for patent technological relevance into five value dimensions: market, technology, law, strategy and economy, for retrieving patents related to reverse osmosis membranes. The indicator layer is further subdivided into criterion layers, which are specified as follows:
- Technical value: Number of IPC classifications, number of cited patents, years of validity;
- Economic value: Remaining years, number of pledge occurrences;
- Legal value: Number of claims, number of document pages;
- Strategic value: Number of inventors, number of simple patent family members;
- Market value: Number of technical subject classifications, patent type, whether it belongs to strategic emerging industries;

3. Data Analysis: This dataset adopts the AHP (Analytic Hierarchy Process) method, combining quantitative and qualitative analysis. It acquires the corresponding data indicators for patent evaluation through patent interface data, and classifies technological relevance from high to low into three grades: A, B and C, where A represents high relevance, B represents general relevance, and C represents relatively low relevance. The comprehensive scoring standard is as follows:
- Grade A: Strategic value ≥ 50 points, economic value ≥ 20 points, market value ≥ 50 points, legal value ≥ 60 points, and technical value ≥ 30 points;
- Grade B: Strategic value ranges from 40 to 50 points (excluding 50 points), economic value ≥ 20 points, market value ≥ 30 points, legal value ≥ 70 points, and technical value ≥ 30 points;
- The remaining cases are classified as Grade C;

4. Data Application: Provide R&D decision-making basis and priority references for technology infringement avoidance for technical personnel in the reverse osmosis membrane field.
