Description

  The present invention relates to a patent map display device capable of displaying patent information extracted from a group of patent information based on a predetermined search condition as a predetermined map.

  Conventionally, when analyzing patent information such as a CD-ROM patent gazette issued by the Patent Office, the target patent information is extracted based on a predetermined search formula and the like, and various types created based on the extracted target patent information Patent map display devices that display a patent map on a screen such as a display are used. Of the patent maps displayed by this patent map display device, for example, a time-series map is used as a map in which the transition of the number of applications in a specific technical field by year is illustrated.

In this time series map, for example, the number of applications is designated on the vertical axis and the application year (or publication year) is designated on the horizontal axis, and the number of applications for each year for each of a plurality of applicants is displayed in a plot. By connecting the plots with a straight line, the change in the number of applications of each applicant can be grasped at a glance. In addition, as a patent document regarding the patent map, for example, the one disclosed in Patent Document 1 is known.
JP 2005-165859 A

  By the way, in such a time-series map, since patent applications are published a year and a half after the application, if the present is the second half of 2004 (after June), all applications in 2002 will be published. Therefore, the number of applications in that year can be accurately displayed in a plot. However, since all patent applications in 2003 and 2004 have not been published yet, the number of applications cannot be displayed in a plot on the map, and the straight line connecting each year is cut off in 2002. ing. For this reason, it is difficult to estimate (predict) the latest data, which is extremely important for the growth of patent information, especially the number of applications, from the map, and to improve the usability of the time series map and improve the efficiency of analysis work. It is difficult.

  The present invention has been made in view of such circumstances, and its purpose is to display an accurate prediction created based on the latest data published in the application, and is easy to use and can analyze patent information. It is an object of the present invention to provide a patent map display device capable of improving the efficiency of the system.

  In order to achieve this object, the invention according to claim 1 of the present invention has at least an input means and a display means, and displays a patent map on the display means based on a search condition input by the input means. A display device for displaying a patent map, wherein the display means predicts information such as the number of applications in a period in which the application has not been published by data analysis of information in a period in which the application has already been published, and displays the information on the patent map. It is characterized by doing.

  The invention according to claim 2 is characterized in that the data analysis is performed by a coefficient obtained by n-order regression analysis of data based on the published number of applications before a predetermined period.

  According to the invention described in claim 1, the display means predicts information such as the number of applications in a period in which the application has not been published based on data analysis of application information that has already been published, Since it is displayed on the map, it is possible to extend the display that has been cut off for a period that has not been disclosed to the public with a prediction line until now, and the prediction line can be used to infer the latest information from the map. While improving usability sufficiently, it is possible to improve the efficiency of patent information analysis work.

  Further, according to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the data analysis is obtained by n-th order regression analysis of data based on the number of published applications before a predetermined period. Since it is performed by a coefficient, a portion not disclosed by a coefficient indicating the shape of a curve or a straight line connecting the number of published applications can be predicted, and the prediction can be performed with high accuracy.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 3 show an embodiment in which a patent map display apparatus according to the present invention is constructed using, for example, a personal computer, FIG. 1 is a block diagram thereof, and FIGS. 2 and 3 are time series map displays. It is explanatory drawing of a state.

  In FIG. 1, the patent map display device 1 has a control device 2 composed of a personal computer body to which a CPU 3, a RAM 4, a ROM 5, an I / O 6, and the like are connected via a bus line 7. A drive 8 such as a CD-ROM including a keyboard 8 and a mouse 9 as an input means, an MO drive, etc. is connected to the input side of the I / O 6 of the control device 2, and various databases 11 are connected to a communication line. 12 is connected. Further, on the output side of the I / O 6 of the control device 2, a display 13 made up of a CRT (including a liquid crystal display) as display means, a printer 14 and the like are connected.

  This patent map display device 1 is set in the CD-ROM drive 10 based on a program read in advance by the CD-ROM drive 10 and stored in the ROM 5 of the control device 2, for example, a CD-ROM patent. Patent information in the publication or patent information from the database 11 obtained via the communication line 12 is searched (extracted) based on conditions such as search items input by the keyboard 8 and the mouse 9. The extracted various patent information is read by the CPU 3 of the control device 2 and the data is totaled to create a patent map, which will be described later, and this patent map is output to the display 13 and displayed on the screen 13a. Alternatively, printing is performed by the printer 14.

  In the patent map display device 1 configured as described above, a time series map 15 as shown in FIGS. 2 and 3 is displayed on the screen 13a of the display 13 as follows. That is, first, when creating / displaying the time-series map 15, for example, an application that is necessary for creating the time-series map 15 by using a predetermined input screen displayed on the display 13 based on the program. Various conditions such as a person and a technical field (IPC and other various classifications), a target period (generally year or year), a publication date or an application date are input and set.

  Then, when a predetermined input is completed on the input screen of the display 13 and a creation display key (not shown) provided on the input screen is clicked, the control device 2 corresponds to an input condition (a predetermined IPC or the like). For example, when the subject patent information is extracted and the applicant is the company A, a time-series map 15 as shown in FIG. 2 is created and displayed on the screen 13 a of the display 13.

  In this time-series map 15, the number of applications is designated on the vertical axis, the application year (or publication year) is designated on the horizontal axis, and the number of applications in each year is designated for the designated applicant A Plots 17a and 18a (black circles in the figure) are displayed, and the plots 17a and 18a are created by connecting them with straight lines 16a and prediction lines 19a. At this time, the plots 17a of the number of cases up to 2003 in Fig. 2, which is already published, are connected by a solid line 16a, and the forecast applications for 2004 and 2005, which are not yet fully published The number of plots 18a is connected by a two-dot chain line (or one-dot chain line or the like) prediction line 19a.

  The plot 18a of 2004 and 2005 is a prediction point because all the cases are not yet fully disclosed. This prediction point is obtained by using the number of cases in a predetermined period (for example, the immediately preceding predetermined period) up to 2003, which has already been fully disclosed, and n-th order regression analysis according to the curve (data) connecting this number. Etc., a prediction coefficient (for example, curvature) for each applicant is obtained, and a transition of a curve or a straight line after 2004 is estimated. In the case of the curve of Company A in FIG. 2, since the central portion has a shape that swells downward, the predicted line portion extends in the direction in which the elongation rate increases.

  When the prediction line is obtained in this way, the number of cases corresponding to the prediction line is displayed as a plot 18a in 2004 and 2005, a plot 17a in 2003, a plot 18a in 2004, and a plot in 2004 18a and the plot 18a of 2005 are connected by the linear prediction line 19a which consists of a two-dot chain line different from the solid line 16a before 2002. Thereby, the transition of the number of applications of Company A is displayed until 2004 and 2005, and the transition of the number of applications up to now can be grasped (estimated) from the screen 13a of the display device 13 at a glance.

  Further, as shown in FIG. 3, when the data of the time series map 15 is the applicant B company of an upwardly bulging curve or the applicant C company of a substantially straight line, the curvature of the curve or the slope of the straight line Is used as a coefficient, the number of cases after 2004 is predicted, and the plots 17b and 17c and the plots 18b and 18c are connected by straight lines 16b and 16c and prediction lines 19b and 19c in the same manner as the company A. .

  Note that the calculation method of the prediction lines 19a to 19c is not limited to the calculation of the coefficient by the nth-order regression analysis. For example, a specific coefficient based on each applicant's past data is calculated and obtained based on this coefficient. It can obtain | require with the various coefficients computed by this method. In addition, the plots 18a to 18c of the prediction lines 19a to 19c are not limited to the same form as the plot 17a of the straight lines 16a to 16c, but are not disclosed using, for example, different plots 18a to 18c. It is also possible to clearly distinguish the display of the entire portion ˜19c from the published portion.

  Thus, according to the patent map display device 1 of the above-described embodiment, the number of applications in the period in which the application is not published is predicted on the screen 13a of the display 13 based on the data analysis of the number of applications already published. Since the prediction lines 19a to 19c and the like are displayed on the time series map 15, the straight lines 16a to 16c that have been conventionally cut off in the non-public year can be extended with the prediction lines 19a to 19c up to the present. The latest information can be estimated at a glance from the time series map 15 by using the prediction lines 19a to 19c, so that the usability of the time series map 15 can be sufficiently improved and the efficiency of the analysis work of the patent information can be improved.

  In particular, since data analysis is performed using coefficients obtained by n-order regression analysis such as curves based on the number of applications published a predetermined period before, a coefficient indicating the shape of a curve or straight line connecting the number of applications published Therefore, it is possible to accurately predict a portion that is not disclosed by the above, and to perform prediction with high accuracy.

  In addition, since the prediction lines 19a to 19c or the plots 18a to 18c are displayed in a display form different from the straight lines 16a to 16c and the plots 17a to 17c of the years that have already been published, the present invention relates to the actually published application. The operator can clearly grasp the straight lines 16a to 16c or the prediction lines 19a to 19c at a glance, and the usability of the time-series map 15 can be further enhanced. Furthermore, since the patent map display device 1 can be constructed using a personal computer, anyone can easily operate according to the display on the screen 13a by incorporating a program in the personal computer in advance. It is possible to analyze the patent information thus obtained at low cost.

  In the above embodiment, the transition of the number of applications for a plurality of applicants is displayed as the time-series map 15, but the time-series map according to the present invention is not limited to this, for example, various types of specific applicants. It can be applied to various patent maps with time as an axis, such as a time-series map based on classification.

  The present invention can be applied not only to a display device constructed using a personal computer but also to a display device using various terminals.
