The main contents of China patent index are:
(1) annual index of classification: Inventions, utility models and designs are arranged by year according to IPC number or international design classification order, and its contents are IPC number/design classification number, publication number GK/ verification number SD/ patent name ZL/ publication number GG, application number, applicant/patentee, patent name, volume number and publication number of patent bulletin.
(2) Annual index of applicants and patentees: arranged in alphabetical order of Chinese phonetic alphabet of names or translations of applicants or patentees by year, and compiled into three parts according to invention patents, utility model patents and design patents. Examples are as follows:
Examination and approval of application for invention patent
K applicant's international patent classification number review number SD application number invention name volume number
A-2 International Instrument Company E 21B10/26CN1008286B8710558.0 Reamer and its measuring tool 6-23.
Yiboni Co., Ltd. A47J43/25CN1008967B87106355.7 Raw food cutter 6-3 1.
No matter referring to the "annual index of classification" or "annual index of applicants and patentees", we can get five data: classification number, invention name, contribution number or patent number, applicant or patentee and issue number.
In addition to the annual index of classification, China Patent Classification Abstracts (published every year since 1985) and China Patent Classification Abstracts (published every year since 1989) edited and published by the Literature Library of the Literature Department of China Patent Office are also reference books for searching China patent literature. These two abstracts respectively include all patent applications for inventions and utility models published and announced every year. There are various annual indexes such as WeChat official account index, announcement number index, application number index and applicant index, which can be searched from different angles.
Both abstracts are divided into eight volumes according to IPC classification, and each volume includes IPC subcategory catalogue, abstracts and various indexes. Because classified abstracts are arranged in the order of IPC numbers, you must have classification numbers to browse abstracts, so each index is actually a comparison table of classification numbers. Patent abstracts can be easily consulted through China patent index and various patent bulletins.
From the applicant's way:
* Note: Here is a table (23 1 page):
Because the China patent index of 1989 only gives the application number, but not the new contribution number (publication number and announcement number), when using this index, besides the application number, classification number, invention name and inventor, the publication number must also be recorded. Find the corresponding patent bulletin by serial number, and then compare the publication (advertisement) number from the patent bulletin index directory to get the specification. In addition, you can also use the book "Application Number/Publication Number Comparison Table", and you can also compare the corresponding publication numbers to achieve the purpose of retrieval.
