How to effectively utilize International Patent Classification (IPC) and search relevant patent rapidly and accurately, become the technical issues that need to address in the present patent research.
Summary of the invention
The object of the invention is to provide a kind of method of the IPC of utilization sorted patent searching.
For reaching above-mentioned purpose, the present invention adopts following technical scheme:
A kind of method of utilizing the IPC sorted patent searching may further comprise the steps:
1) set up an IPC taxonomy database,
2) utilize IPC classification in this IPC taxonomy database of keyword retrieval;
3) according to step 2) result for retrieval, the relevant IPC classification of screening;
4) the relevant patent of IPC systematic searching after the utilization screening.
As a kind of optimal way of the present invention, described IPC taxonomy database is set up according to portion, big class, group, big group, group.
As a kind of improvement of the present invention, described step 2) retrieval displaying contents as a result comprise big group, group.With convenient screening.
As another improvement of the present invention, described step 2) retrieval displaying contents as a result also comprise big class, group.Further facilitate screening.
One improve described step 2 again as of the present invention) before, also comprise near synonym, the synonym character library step of setting up keyword, utilize these keyword retrieval near synonym, synonym character library earlier; In described step 2) in utilize this keyword and near synonym thereof, synonym to retrieve IPC classification in this IPC taxonomy database, merge result for retrieval.
By technical solution of the present invention, can effectively utilize International Patent Classification (IPC) and search relevant patent rapidly and accurately, reduced retrieval time, improved recall precision.
Embodiment
With next preferred embodiment, describe the present invention in detail.
A kind of method of utilizing the IPC sorted patent searching may further comprise the steps:
1) provide the IPC of an electronic edition to classify, this IPC classification can be various language, various version.According to the IPC classification characteristics, set up database according to the mode of portion, big class, group, big group, group, each the IPC book of final entry that retrieves can adopt multiple mode to represent, for example expression in such a way:
Portion/big class/group/big group/group's (explanation of portion)/(explanation of big class)/(explanation of group)/(explanation of big group)/(explanation of group); For example:
" B21D051/26 (operation; Transportation)/(sheet metal or pipe, rod or section bar do not have cut or processing substantially; Punching press)/(essentially no cutting metal mechanism processing; Metal stamping)/(make hollow products (with the B21K21/00 that goes into of thick-walled pipe or inhomogeneous pipe))/(iron flask or listen; (configuration of outlet goes into 51/38 to its permanent closure; B23K is gone in welding or soldering) (2)) ".
Be the expression mode of big group of standard, less than three-figure, mend " 0 " in its front in big group categories, for example, " B21D51/26 " can be expressed as " B21D051/26 ".
In addition, can also adopt, only represent that then the mode of different piece shows for as long as have same section in " portion, big class, group, big group, group " in the IPC classification.
2) provide near synonym, the synonym character library of an electronic edition, the near synonym of collecting in this character library, synonym can be compiled from dictionary, technical manual, patent documentation and form.Utilize the keyword that needs retrieval to retrieve these near synonym, synonym character library earlier, and obtain result for retrieval.Can also screen the result who retrieves earlier this moment, the word that the deletion relation is little.The characteristics of the patent documentation that can also retrieve as required add relevant keyword.
3) utilize step 2) in the word or the keyword that obtain, by keyword in the computer checking IPC classification, i.e. explanation in " portion, big class, group, big group, group "; Obtain relevant IPC tabulation.With " welding " speech is example, (IPC) in the 7th edition, finds 131 relevant patent classifications at " International Patent Classification (IPC) " of Chinese edition altogether, because content is too much, following selection portion go-on-go hitch fruit only, and win wherein partial content (seeing Table), step 3) is described.Be listed as follows,
Table one
| Numbering | Portion | Big class | Group | Big group | Group |
| 1 | B (operation; Transportation) | The essentially no cutting metal mechanism processing of B21; Metal stamping | B21D (sheet metal or pipe, rod or section bar do not have cut or processing substantially; Punching press) | B21D051 (manufacturing hollow products) | B21D051/26 (iron flask or listen; Its permanent closure) B23K is gone in welding or soldering |
| 2 | B (operation; Transportation) | The essentially no cutting metal mechanism processing of B21; Metal stamping | B21F (processing of wire rod or processing) | (line is connected with line or other metal material or product B21F015; Use the link of line) | B21F015/08 (with soldering or welding) |
| 3 | B (operation; Transportation) | The essentially no cutting metal mechanism processing of B21; Metal stamping | B21F (processing of wire rod or processing) | B21F019 (metal coat of wire rod) (, going into B23K) as covering or plating with soldering or welding | B21F019/00 (metal coat of wire rod) (, going into B23K) as covering or plating with soldering or welding |
| 4 | B (operation; Transportation) | The essentially no cutting metal mechanism processing of B21; Metal stamping | B21F (processing of wire rod or processing) | B21F027 (manufacturing of gauze 1, i.e. gauze goods) | B21F027/10 (having soldering or welding hands over justice to put) |
| 5 | B (operation; Transportation) | B23 (lathe; Exclude the metal processing of other class) | B23K (soldering or sealing-off; Welding; Coat or plating with soldering or welding method; The spot heating cutting is cut as flame; Process with laser beam) | B23K003 (be used for soldering, be not specially adapted for specific process) | The B23K003/04 firing equipment |
For the relevant near synonym of " welding " speech or the keyword of synonym or correlation technique, for example the retrieval of " soldering " is identical with the retrieval of " welding ", no longer enumerates result for retrieval at this.When computing machine is finished retrieval to " welding " and near synonym thereof, synonym, other keyword, merge relevant result for retrieval, remove the IPC classification that repeats.
4) the relevant IPC classification of manual screening; Remove incoherent IPC classification; With table one is example, and it is irrelevant with " welding " to be numbered 1,3 two IPC classification, so can select deletion.
5) utilize 4) results of screening, the relevant patent of retrieval.At this moment, can only utilize the IPC classification of screening back to carry out patent retrieval as required,,, retrieve as inventor, applicant etc. perhaps in conjunction with other keyword.
