At 2012 OECD guested ediction of patstat conference people from EPO staff announced new developments for patstat db for coming months.
Most relevant are:
TLS217, cointaining eclas, will become tls224 since cpc will replace ecla.
Cpc (achronim of cooperative patent classification, developed jointly from EPO and USPTO) is an evolution of ecla extending it upto 250.000 entries. more on: www.cpcinfo.org
Another change will affect inpadoc families table TLS219 where replenished (artificial) publications will be removed.
In TLS211 replenished publications ids will be in 900.0000.000 series.
Fields appln_id, publn_id will be changed by removing leading spaces.
Citations table quality will be improved by adding jp kr cn citations in 2013 (nowadays data exist but with a lot of gaps).
Espacenet will be enriched with south american and arabic patent authorities (also Morocco, Jordan...) and soon will be transferred into patstat.
As new product, eu register data (http://www.epo.org/searching/free/register.html) will be distributed in Csv starting from 1st quarter 2013 as beta public test.
Since october 2013 data public distribution will start. Data size should be 22 gb, 2,5 gb zipped.
Some news arrived also about unitarypatent: the goal is to have the first grant in 2014, it will cohexist with EP patents and very likely at data level will have same application and pubblication authority (ep) but probably a new appln kind.
Eventually, t has been rumored that in a fortcoming ediction orbis (http://www.bvdinfo.com/products/company-information/international/orbis) will give link to patstat.
