O-Film — AI-Powered Intelligent Patent Document Extraction System

O-Film Group Co., Ltd. is a well-known optical and optoelectronics enterprise in China, with business spanning smartphones, consumer electronics, smart vehicles, and other fields.

In daily R&D work, a large number of patent documents related to lenses need to be processed (in PDF format), which contain extensive technical parameter data. Under the traditional approach, staff members must manually extract parameter information from patent PDF documents and transcribe it into Excel spreadsheets. This process is highly inefficient and prone to human error, seriously compromising the accuracy and consistency of the data.

flysinfo has built an intelligent lens parameter patent data extraction system for O-Film using AI technology:

Intelligent OCR Recognition — Supports multi-language mixed document recognition, including Chinese, English, Korean, Japanese, and German, with an accuracy rate exceeding 98%;

Precise Information Extraction — Automatically identifies and extracts key information fields such as publication number, patent holder, and patent number;

Cemented Lens Processing — Intelligently identifies and accurately separates the individual parameters of each lens within a cemented lens assembly;

Data Normalization — Standardizes extracted data such as focal length to ensure data consistency.

The system is built on the Coze platform, adopts a modular design, and supports web-based querying and data export functionality.

After rigorous testing and verification, the system has met or exceeded the expected standards across all six acceptance criteria:

Overall Score of 96.35% — All acceptance criteria met or exceeded expectations;

Recognition Accuracy of Over 98% for Standard Chinese and English Tables — Far surpassing the precision of manual processing;

Successfully Processed 100,000 Patent Documents — Significantly improving R&D work efficiency and laying a solid data foundation for subsequent research and innovation.
