Recently, patent images are growing importance and thus patent image retrieval is a growing area of research. However, most existing patent image retrieval systems use edges extracted in the images, whose performance is affected by the quality of edge detection in the image pre-processing step. To overcome this disadvantage, we propose a SURF-based patent image retrieval method which uses the morphological characteristics of the images. The proposed method detects SURF interest points with directions and computes regional histograms. We apply the proposed method to a patent image database with 2000 binary images and we show the proposed retrieval system achieves excellent results, even when the images have some loss or degradation.

Images are an important element in patents and many experts use images to analyze a patent or to check differences between patents. However, there is little research on image analysis for patents partly because image processing is an advanced technology and typically patent images consist of visual parts as well as of text and numbers. This study suggests two methods for using image processing; the Scale Invariant Feature Transform(SIFT) algorithm and Optical Character Recognition(OCR). The first method which works with SIFT uses image feature points. Through feature matching, it can be applied to calculate the similarity between documents containing these images. And in the second method, OCR is used to extract text from the images. By using numbers which are extracted from an image, it is possible to extract the corresponding related text within the text passages. Subsequently, document similarity can be calculated based on the extracted text. Through comparing the suggested methods and an existing method based only on text for calculating the similarity, the feasibility is achieved. Additionally, the correlation between both the similarity measures is low which shows that they capture different aspects of the patent content.

The purpose of this study is to obtain the patent for extracting the color map and color chip from the color image source and to develop color image map for fashion design. For this study, fashion image maps were produced from 210 pictures with Adobe Photoshop CS2 program targeting 200 university students from 2004 to 2006. The procedures for extracting the color map and color chip included providing the color image, the filtering phase, the segmentation phase, the extraction phrase, and the arrangement phase. Based on the results of this study, patent application was made to KIPO(Korean Intellectual Property Office) for this invention. The following effects can be expected from the standpoint of design based on the case study. First, it is a straight forward procedure to extract a color chip and color map from a color image. Second, it can be applied to various art works based on the recombination of colors as representative colors can be extracted from the related color image that combines a variety of colors. Third, desired colors can be selected based on the taste cluster classification or sensibility axis of design by extracting the representative color from the color image.

With continuous news headlines related to patents in the public media, awareness of patents' value is spreading, and patents are valuable not only to a firm but also to consumers. Therefore, this study makes an effort to explore the theoretical mechanism of the effects of patent infringement litigation (PIL) on customers. More specifically, this study examines the influence of PIL on customer-based brand equity (CBBE) and brand innovation image (BII). Based on this study's findings, PIL's outcomes directly affect BII, which in turn indirectly affects CBBE. That is, people will evaluate a winning brand as a highly innovative brand, which contributes to higher brand equity. However, in regards to PIL's direct effect on CBBE, there are some differences between Apple and Samsung. In the case of Apple, the winner image positively affects only one dimension of CBBE, brand loyalty, while for Samsung, the plaintiff's image negatively affects brand loyalty.

Objectives Tongue diagnosis is an important diagnostic method in traditional Eastern medicine, and it has a high potential to be used in the future healthcare because of easy, quick, and non-contact measuring features. Recently, research and development efforts on computerized tongue diagnosis systems (CTDS) have been active that led to the technical advancements in the field of photographing techniques, image extraction and classification algorithms. In this study, we analyzed the trends in the CTDS patents. Using the WIPS search engine (www.wipsglobal.com), quantitative and qualitative patent analyses were performed through Korea, China, Japan, U.S.A and Europe. Methods For a systematic search and data analysis, we defined patent categories based on the application area and technical details. By applying thus-obtained categorical key words, we obtained 360 relevant patents on photographing techniques, image extraction and classification algorithms for the purpose of diagnosis or security. Results As a result, companies related to image acquisition, medical imaging and mobile devices and research groups of universities in East Asia were major patent applicants. In all the five countries, the number of patents have been increasing since 1980. In particular, technology related to color correction and image segmentation were most actively patented categories, and expected to continue a high application rate.

This study attempted to creat patent map 163 cases of patent for technology of apparel design using computer technology and researched the trend of Patent application by count교, technologies, applicant and filing date. In regard to application by country, the United States mark the first place with 99 cases (61%), Japan marks the second with 34 cases (21%), Korea the third with 19 cases (12%). Comparing the patent applications in specialized technologies, we find the United States is overwhelming the technologies for garment Production Process, Patterning Process and preparatory process, and Japan is currently undergoing development work in this area, while most of Korean applications are focused in the technologies for selection or substitution methods related to Purchase and sale of apparels, body image and design service Therefore, it is required to preoccupy and defend patent rights as well as develop technologies aggressively and extensively in preparation for the expansion of e-commerce market. Analysing the speed of progress in technology in terms of number of applicants and application cases, we can say it entered into developing stage from the middle of 1990s and it seems that they will continue the development work from now on. in case of Korea, they began in 1996, somewhat late, but reached a similar level with the United States in 2000.
