Patentsview mysql upload scripts

In previous days the new version of Patentsview database has been release

The PatentsView initiative was established in 2012 and is a collaboration between USPTO, US Deptartment of Agriculture (USDA)⁽¹⁾, the Center for the Science of Science and Innovation Policy, New York University, the University of California at Berkeley, Twin Arch Technologies, and Periscopic.
The PatentsView platform is built on a newly developed database that longitudinally links inventors, their organizations, locations, and overall patenting activity. The platform uses data derived from USPTO bulk data files. These data are provided for research purposes and do not constitute the official USPTO record.

From this link you can download my scripts for mysql to upload the new data.

2017 PatentsView Workshop on Engaging User Communities

The US Patent and Trademark Office’s Chief Economist has open  invitations to the 2017 PatentsView Workshop on Engaging User Communities.

The workshop is open to the public and will be held on Friday October 6, from 8:30am – 12:30pm on the USPTO campus in Alexandria, VA.

USPTO will officially launch at the workshop the PatentsView Community Site, updated data visualization with export functionality, and new data fields that can be accessed across PatentsView tools.  This year’s updates are based on feedback gathered by the user community at the 2016 PatentsView workshop.  The new Community Site includes a moderated forum for user inquiries and a Data in Action page for sharing analyses, visualizations, and publications. 

The goals of the workshop are:

(1) to launch the new Community Site and Data Visualization features;

(2) to present newly parsed and available patent data fields; and

(3) to gather feedback from patent data and analytics user communities in order to set priorities for future PatentsView open data products.  

More informations here.

Agenda buildup is in progress and it will be fully delivered in the coming weeks. 

PatentsView Inventor Disambiguation Technical Workshop

On behalf of the US Patent & Trademark Office, the American Institutes for Research (AIR) is hosting an inventor disambiguation technical workshop.  USPTO is seeking creative new approaches to get better information on innovators and the new technologies they develop by disambiguating inventor names.

AIR invites individual researchers or research teams to develop inventor disambiguation algorithms using US patent data. The top fifteen teams will be invited to present their results at the final workshop, which will be held at USPTO headquarters September 23 and 24.  The researcher or team that contributes the most effective algorithm will receive a $25,000 stipend.

July 1st is the Deadline for prospective participants to submit a 1-page “intent to participate” document. This includes any requests to incorporate additional data, software, or hardware requirements. All teams with proposals deemed to be reasonable (by the judges’ panel) will be invited to participate.

Additional information is posted at www.dev.patentsview.org/workshop, together with the training datasets.

Patent attorney for USPTO

As wikipedia describes (http://en.wikipedia.org/wiki/Patent_attorney)
A patent attorney is an attorney who has the specialized qualifications necessary for representing clients in obtaining patents and acting in all matters and procedures relating to patent law and practice, such as filing an opposition. The term is used differently in different countries, and thus may or may not require the same legal qualifications as a general legal practitioner.

Such data may be useful to be introduced f.i. in applicants disambiguations (two very similar names filing via  the same attorney are more likely to be the same company...)

Bytheway suc data is not available in patstat, but is in USPTO data

One example of website displying suh data is: http://www.patentmaps.com/attorney/index.html

About Us patent reform

@this link
http://patentmanager.blogspot.com/2011/09/us-patent-reform-made-easy-whats-in-it.html
you may find an exaustive synthesis of waht will change with the new patent reform recently approved in USPTO.

Link between US patent classes and IPC

This one comes straight from epo patstat forum, you may find the original @ this link.

If you are in need of matching US Patend Classification (USPC in short) against IPC, there are some web pages in USPTO web site that may be useful:


USPC-to-IPC Reverse Concordance (entries are grouped by IPC notation, rather than USPC notation): http://www.uspto.gov/web/patents/classification/international/ipc/ipc8/ipc_concordance/ipcsel.htm

US-to-IPC Concordance Pages from Classification Home (by choosing US-to-IPC8 Concordance in the radio button) : http://www.uspto.gov/web/patents/classification/index.htm

For more details, see USPTO dedicated page:
http://www.uspto.gov/web/patents/classification/international.htm

Double publication numbers by application id in USPTO

As previously posted, several application authority may have more than one publication number referring to the same application id.

In the case of uspto these are the main publication kind pairs of publication numbers referred to the same application id. It may be useful for creating a disambiguation table.

kind1	kind2	count
'A'	'B1'	3895
'A'	'B2'	124
'A'	'C1'	356
'A'	'E1'	12
'A1'	'A2'	521
'A1'	'A9'	1662
'A1'	'B1'	18410
'A1'	'B2'	845793
'A1'	'H1'	43
'A2'	'B2'	169
'A9'	'B2'	768
'B1'	'B2'	142
'E'	'F1'	59
'P1'	'P2'	424
'P1'	'P3'	1686

Bytheway, counting the difference in months among filing date and publication date for the first of the two pubblication kinds, we get the following result:

months	# of applications
4	50501
5	53963
6	130103
7	111533
8	67594
9	48504
10	33086
11	26268
12	20754
13	15320
14	13855
15	11927
16	9346
17	7075
18	186961
19	32484
20	6354

Above 95% of applications listed in the first table are published before 18 months (cases in month 19 may be a rounding error), conforting so our hipothesys that the first of the 2 publication is due to the 18 month publication law.

USPTO persons data quality

In a previous post I analized geographic data quality of inventors in PATSTAT, for all the data contained.
The results for USPTO where not so good...

APPLN_AUTH	inventors	no state	no zip	no country	no address	no city
US	5960856	86%	98%	21%	97%	25%

In order to understand how is the trend across years (if data quality is improving or noise is spread allover the data) I selected applicant/inventors who filed after 31/12/1999 applications type “A” (patents of invention);
the results was that 1% have no country and about 2% have no city (so it could be impossible to assign a region/NUTS2 code).

distinct appl/inv	2774408
ctry code blank	29858	1,08%
city blank	56119	2,02%

If we investigate by inventor/applicant county whether  there may be some nation having a BIAS (only for those countries having more than 100 inventors/applicants) we see that those who have values above average are countries outside Europe, so not included in some regional reclassifications like NUTS2.

Inventors data in patstat: Epo vs uspto

Patstat stores data about applicants and inventors inside a table with the prefix TLS206, indexed using a field named PERSON_ID that can be linked to the applications via table TLS207_PERS_APPLN linking each person_id to an application id (appln_id)Patstat DVD provides two versions of TLS206: the first TLS206_PERSON is a comma separated value file containing mainly the fields name, address and country code.

TLS206_ASCII instead contains the same information already parsed (and also something more, see below for fields list): name is splitted into last, first and middle name; address into street, city, state and zip code.

Data origins for person names and addresses:


1) EPO Register for EP patent applications; details are those that were the most recent in the EP Register at the time of extraction of the data.

2) OECD patents database for US data post 1976-01-01 up to and including November 15th 2005 for Published Grants.

3) PATSTAT weekly file extracts from USPTO website for Published Grants from November 22nd 2005 until today;  Published Applications  from September 29th 2005 to today inclusive.

4) Inventor & Applicant names for US PTO Published Applications from March 1st 2001 to September 22nd 2005 from DOCDB ,  data-format="docdba".

5) all other names  from DOCDB , data-format="docdba" (US data for names and addresses for patents published before 1976-01-01 is taken from the EPO's DOCDB Database)

Counting patstat patents by application year

Here below a small table created by counting by application year patents applied @ EPO vs patents applied @ USPTO. Data have been counted from september 2009 data, starting from 1980.
Note that the peak is in 2004 for US and 2006 for EPO due to the examination lag (for both office) and also to the delay in including Us patents in patstat, for USPTO.
Nota also that 2001 sudden rise of 100% of patent count for USPTO is due to a change in the US Patent Law, since US Patent and Trademark Office was obliged to publish patent applications from 29 November 2000. However USPTO internal publishing system meant that publication actually began in March 2001.

appl year	EPO pat#	USPTO pat#

Origin of citations in European Patent Office

Whenever you'd need to understand who introduces a citation to a patent in PATSTAT, you may look at  table TLS212_citation, where you may find the field CITN_ORIGIN.

The content of such field may be any of these


0 - SEA- citations introduced during search
1 - APP- citations introduced by the applicant
2 - EXA- citations introduced during examination
3 - OPP - citations introduced during opposition
4 - 115- citations introduced according to Art 115 EPC
5,6 not public



Let's see the content of this field in EPO patents (count made on PATSTAT 10/2009 grouping by publication numbers)

ORIGIN        COUNT OF CITATIONS

0                    22985072

1                     6175203

2                      178744

3                       15839

4                       13533

While in in USPTO patents..
(count made with same criteria as above)

ORIGIN        COUNT OF CITATIONS
0              37425072 
1              15534910

The higher number of applicant introduced citations is due to the "duty of candor" rule which imposes the disclosure of all prior art.
