A STUDY ON TECHNOLOGY TREND OF CAMERA BY USING FI CODE IN JAPANESE PATENT

In development of technology and product, it’s important to make decisions based on technology trend. Some previous studies obtained technology trend based on patent information. In our previous study, we tried to investigate the state of innovation and the emergence of dominant design by using patent information. We analyzed inkjet printers and NC machines with theme codes and F term codes in Japanese patent classification codes. In this study, we tried to know the change of technology of other products other than inkjet printers or NC machines by using patent information. The target product of this study is camera. Camera products changed its key technology of imaging and recording from analogue film to digital imaging sensor and semiconductor memories. We attempted to obtain this change by using patent information.

S Curve

This research is aimed at identifying the trend of technology and time emergence of the dominant design of inkjet printer and NC machine by using F-term in Japanese Patent. F-term was employed instead of International Patent Classification (IPC) because of the multi view point of the theme and it provides the certain technical area. The firm‘s product entering time to the market was evaluated to the S curve of the product lifecycle and technology life cycle was also investigated.

Technical Solutions

Informational and analytical studying patent documentation shows the patenting situation either in general in a specific technological area or the patent activity of innovation entities, taking temporal dynamics and the territorial basis into account. Patent-information investigation was carried out in order to get acquainted with the level of photogrammetry technology development and determine its current application areas. Statistical and intellectual patent document text analysis was the basis for relevant data array grouped in 8680 patent families’ creation. The prepared report contains a graphical display of selected patent documents array, related to research topic, analytical and statistical processing. The level of inventive activity was assessed; the world patenting dynamics and location in this technical field were considered. The main groups on the International Patent Classification, as well as the main technological directions, where technical solutions related to the object of study to be patented, are identified. Information on the leading applicants/ patent holders in this technical field is provided; the list of the most cited patent documents is considered.

Intellectual Assets

Patents are critical intellectual assets for any competitive business. With ever increasing patent filings, effective patent prior art search has become an inevitably important task in patent retrieval which is a subfield of information retrieval (IR). The goal of the prior art search is to find and rank documents related to a query patent. Query formulation is a key step in prior art search in which patent structure is exploited to generate queries using various fields available in patent text. As patent encodes multiple technical domains, this work argues that technical domains and patent structure have their combined effect on the effectiveness of patent retrieval. The study uses international patent classification codes (IPC) to categorize query patents in eight technical domains and also explores eighteen different combination of patent fields to generate search queries. A total of 144 extensive retrieval experiments have been carried out using BM25 ranking algorithm. Retrieval performance is evaluated in terms of recall score of top 1000 records. Empirical results support our assumption. A two-way analysis of variance is also conducted to validate the hypotheses. The findings of this work may be helpful for patent information retrieval professionals to develop domain specific patent retrieval systems exploiting the patent structure.
