1. Patent data distribution for Japan Patent Office (JPO)

Hideo Aono (DDBJ Patent Annotator)

1. Introduction

In this column, I would like to introduce about patent data exchange in the International Nucleotide Sequence Databases (INSD) and Japan Patent Office (JPO) data.

2. Data distribution from INSD

DDBJ is constructing INSD with EMBL-Bank in EBI (European Bioinformatics Institute) and GenBank in NCBI (National Center for Biotechnology Information).
INSD distributes not only scientific data but also patent data transferring from each patent office as follows.

Patent data contains nucleotide sequence and amino acid sequence. After distributed nucleotide sequence data, it was exchanged among INSD. However, INSD does not exchanged amino acid data.
DDBJ distributes JPO and KIPO amino acid data on DDBJ anonymous FTP site.

DDBJ anonymous FTP:
JPO file: jpo_ddbj_aa*.seq.gz (*=file number)
KIPO file: kipo_ddbj_aa.seq.gz

3. Patent data summary for JPO

3-1) JPO data

DDBJ distributes nucleotide sequence and amino acid data containing publication of unexamined patent applications. Therefore, new distribution sequences do not have the patent right. When you would like to confirm the progression status of patent examination, you need checking the registration status using by retrieval site for IPDL (Industrial Property Digital Library) in Japan.

3-2) Kinds of JPO patent data and distribution frequency

DDBJ receives three kind of patent data from JPO;

  1. Publication of patent applications
  2. International application published under the Patent Cooperation Treaty (PCT)
  3. Japanese translations of PCT international publication for patent applications

DDBJ distributes the regular data at once a month and infrequently irregular data in some cases.

3-3) Patent data contents

JPO data of DDBJ flat file (FF) has enough information such as the front page of patent publication by the following contents; sequence, organism name, invention title, applicant name(s), inventor name(s), publication number, publication date, application number, application date, priority date, comment and sequence's feature information.

Example: DL000001

3-4) Patent applied sequence submission to DDBJ

If you have sequence(s) for patent application, you do not have to submit to DDBJ. Because JPO transfers those sequences to DDBJ and your sequence(s) will be opened to the public through DDBJ. However, if you need the accession number to submit a paper before apply for a patent, you should care since sequence becomes public knowledge in case of released from DDBJ. In this case, please confirm to JPO before your submission.

4. Author comments

I hope to help understanding about JPO patent data. I will introduce about KIPO data and retrieval method of patent sequence in KIPO related organization at next column.

2. Patent data distribution for Korean Intellectual Property Office (KIPO)

Hideo Aono(DDBJ Patent Annotator)

1. Introduction

In previous column, I introduced about patent data for Japan Patent Office (JPO). In this column, I would like to introduce about patent data of Korean Intellectual Property Office (KIPO) and data search service in DDBJ.
DDBJ has just distributed some of KIPO data. Therefore, I would like to introduce also search service of patent applied sequence at Korean Bioinformation Center (KOBIC) and Korea Intellectual Property Rights Information Service (KIPRIS) as KIPO related organization.

2. Summary of KIPO data

DDBJ has provided the nucleotide sequence and amino acid sequence containing publication of unexamined patent applications from KIPO since March 2008.

KIPO data is transferred to DDBJ as follows;

  1. KIPO sends the patent sequence data to KOBIC.
  2. By cooperation of Dr. Byungwook Lee in KOBIC, KIPO submission files are made by him and transferred from KOBIC to DDBJ.
  3. DDBJ exchanges the data format and distributes KIPO data.

DDBJ distributed the following 282,161 entries assigned the prefix "DI" of KIPO accession number, until now.
KIPO data submission is suspended by the problem of submission format from April 2009. Therefore DDBJ is discussing about efficient method for data exchange with KOBIC and KIPO.

Nucleotide sequence data : DI000001 - DI168562 (168,562 entries)
Amino acid sequence data : DI500001 - DI613599 (113,599 entries)

Please see Data example of Fig.1 and Fig.2.

3. Data search for KIPO data

DDBJ

DDBJ provides the search service for KIPO nucleotide and amino acid sequence (Table.1).

getentry ARSA BLAST File ftp service
Nucleotide sequence Ο Ο Ο PAT division files (*1) in DDBJ release
Amino acid sequence Ο × Ο Cumulated file on DDBJ anonymous site (*2)

*2 Cumulated file (kipo_ddbj_aa.seq.gz) has all KIPO amino acid data.

Korean Bioinformation Center (KOBIC)

PATOME@Korea is Koran patent database for nucleotide and amino acid sequence in KOBIC. "PatSeq DB search" can search by application number, applicant name, invention title in English. In addition, PATOME@Korea provides the similarity search for DNA and protein against patent applied sequences in Korea (Please see Fig.3).

column_23
Fig.3, Top page of PATOME@Korea;

Korea Intellectual Property Rights Information Service (KIPRIS)

KIPRIS is the search system of Korean patent publication. PATOME@Korea can search the patent publication in Korean. In contrast, KPA (Korean Patent Abstracts) search of KIPRIS can refer the front page and abstract of patent publication in English retrieved by keyword, application number, publication number, applicant name and inventor name (Please see Fig.4). K2E-PAT (Korean to English Patent Automatic Translation) has pay service for the provision of full text by English machine translation.

Author comments

KIPO suspends their submission to DDBJ. We will restart KIPO submission as soon as possible.
At next column, I will introduce about the structure of DDBJ Flat Files (FF) for JPO patent data.

3. Flat File structure for Japan Patent Office (JPO) -First part-

Hideo Aono (DDBJ Patent Annotator)

1. Introduction

I introduced about patent data of Japan Patent Office (JPO) in first column and Korean Intellectual Property Office (KIPO) in second column. In this time, I would like to explain about Flat File (FF) structure for JPO nucleotide and amino acid sequence data as two parts. I will introduce about JPO data property, summary of FF structure and relationship between patent application contents and description part on FF in first part.

2. Property of JPO data FF

JPO data FF has fundamental application information of patent publication compared with FF for United States Patent and Trademark Office (USPTO) and European Patent Office (EPO). Because JPO makes the submission file (Fig. 1) containing application information based on WIPO (World Intellectual Property Organization) ST 25 format submitted from applicants. Thereafter, DDBJ makes FF reflected almost contents of JPO submission file (Fig. 2).


Fig.1 Example of JPO submission file

3. FF structure and description contents

I showed FF structure for nucleotide sequence data dividing by six parts (LOCUS Block, SOURCE Block, REFERENCE Block, COMMENT Block, Feature Block and Sequence Block) as different color with sample data and description contents in Fig. 2.

5. New COMMENT format for Japan Patent Office (JPO) data

Hideo Aono (DDBJ Patent Annotator)


Introduction

DDBJ makes an improvement of COMMENT Block on Flat File (FF) for Japan Patent Office (JPO). In this column, I would like to introduce new format of COMMENT Block in detail.

DDBJ re-constructed FF of all JPO entries to reflect new COMMENT format.
New format of Nucleotide sequence data has been released since DDBJ release 90 (Fig.1) and Amino acid sequence data has been distributed JPO cumulated files on Anonymous FTP since September 2012 (Fig.2).

1. New format of COMMENT Block
JPO data has almost basic information for patent application. Therefore, user can get its information without referring patent publication.
However, since patent information was set on different part of FF, user had to know the FF structure to get them in advance. In specially, applicants name is only set JOURNAL line on REFERENCE Block (Fig.3 & Fig.4).

   Fig.3 Applicant name on REFERENCE Block
   

Therefore, DDBJ made describing basic patent information on COMMENT Block as follows (Fig.4).

   Fig.4 Description of each line on REFERENCE [A] and COMMENT Block [B]
   

COMMENT Block was added new lines of PA (Applicant name), PT (Invention title) and PS (Sequence number) in all nucleotide and amino acid sequence data (Table.1).

   Table.1 New lines of COMMENT Block

hNew line nameh Description
PA line Applicant name
JOURNAL line on REFERENCE Block is also described (Fig.3).
PT line Invention title
DEFINITION, TITLE line on REFERENCE Block are also described (Fig.1 & Fig.2).
PS line Sequence number
Sequence number for Sequence listings setting after prefix letter "N".

2. Sequence number
2-1:

There was mismatch problem of Sequence number between Sequence listings and JPO submission file. Old format FF was not described Sequence number of Sequence listings. Therefore, DDBJ added PS line on COMMENT Block to set its number.

2-2:
When applicants applied patent, they made Sequence listings according to the guideline: WIPO ST.25. It was put ordering number from 1 to nucleotide and amino acid sequences based on patent claims by applicants.
On the other hand, JPO changes sequence order and makes nucleotide sequence block and amino acid sequence block from Sequence listings when they make the submission files to DDBJ. After that, they set new Sequence number in order of nucleotide sequences, amino acid sequences (Table.2).

   Table.2 Correspondence of Sequence number between Sequence listings and FF
   

2-3:
Sequence number indicated by JPO is reflected with patent publication number on DEFINITION, KEYWORDS, JOURNAL line of REFERENCE and PN line of COMMENT Block.
Publication of patent applications and Japanese translations of Patent Cooperation Treaty (PCT) international publication for patent applications have same format of publication number with "JP". PCT international publication for patent application has "WO" in head of publication number (Fig.1, Fig.2 and Table.3).

   Table.3 Description part and Format of patent publication on FF

hDescription part of FFh hFormat of patent publicationh
DEFINITION
KEYWORDS
PN line of COMMENT Block
JP[space]Patent publication number[-A/]Sequence number
WO[space]Patent publication number[-A/]Sequence number
JOURNAL line of REFERENCE Block JP[space]Patent publication number[-A][space]Sequence number
WO[space]Patent publication number[-A][space]Sequence number

2-4:
Sequence number Sequence listings are set after prefix letter "N" on PS line. Therefore, you can retrieve appropriate data by ARSA (All-Retrieval of Sequence and Annotation) with publication number and "N" with Sequence number.

Author comments
DDBJ continues to make an improvement of Patent FF for user. As next step, we are planning FF put on direct link of the patent publication.
