Getting started. What databases?
Free patent databases: WIPO Patentscope: WIPO stands for World Intellectual Property
Organization. The database has access to the PCT issued patentsand patent applications. Machine translation available
EPO Espacenet: The European Patent Office has the best
collection of free tools for patent search. Espacenet has accessto the PCT database and other databases like INPADOC, etc. .Machine translation available. They also have a complex trainingprogram, starting with an assistant
UPRP - Public, it has got a register of all the polish patents. It is
difficult to check polish patents using international searchengines (no abstract, claims, sometimes not even the patent)
Free Patents Online: Easy to use for the novice, it has anexcellent patent coverage and good advanced options

Getting started. What databases?
Commercial patent databases:
Global Patent Index (GPI): The cheapest option, combines thecoverage of Espacenet with the detailed search capabilities of acommercial database
Boliven. Cambridge Intelligence. It hosts a searchable online
database of over 100 million scientific documents (60% patents).Easy to use and provides some useful statistic analysis.
PatBase. Relies on the EPO-produced INPADOC/DOCDB family filefor bibliographic information, and the EPO's BNS image databasefor worldwide patent document images
Thomson Innovation: The company possesses an array of patentsearch and analysis tools with the widest database that makes it thebest online resources provider and also the most expensive.

Patentscope advanced and field
combination allow to conduct more
complicated searches based on a quite
typical syntax: boleean terms (and, or,
not), proximity search (near), and
parenthesis grouping: (diagnosis OR
cancer) AND microarray is not the same
as diagnosis OR (cancer AND microarray)
http://patentscope.wipo.int/search/en/he
lp/querySyntaxHelp.jsf
Field combination is my favourite option
because it gives an account of the search
results. I never read when the number is
above 300.
WIPO does not group family members soa 300 hundred result will give many
patents with identical applicants, title,
inventors that are issued in different
countries. It gets down to 100 or less.

What is GPI
A cumulative database updated on a weekly
basis (every Friday at 12.00 CET) included into
the Patent information services package.
Includes all bibliographic data coming from
DOCDB. Patent documents supplied to the
EPO by over 80 countries

What can I use GPI for?
The GPI database has been designed to enhance accessto DOCDB.
worldwide state-of-the-art searches. GPI contains thebibliographic data of more than 75 million patent
publications supplied to the EPO by over 80 patentauthorities, allowing you to perform detailed technicaland commercial searches.
worldwide patent watches. GPI provides searchfacilities to restrict the scope of your search to the
most recent publications, letting you carry out detailedtechnical and commercial searches at weekly level

Search CriteriaDifference with the
free searchers
Espacenet has a limit of 10 search terms per field. The othersearchers have either lower limits or allow only to AND, ORoperators
Patentscope has a very complete search form but no family filters
and poor statistical analysis tools. Free patents online has got an excellent coverage of US, WO/PCT,
EP patents but bad access to images, no statistical analysis and nodownloading of result lists (at least for free)
GPI allows to filter the results by family representatives (it can
greatly reduce the number of patents in the result list), and todownload it to perform statistical analisys . The amount ofoperators and conditions of search (show only familyrepresentatives, look for patents which cite certain prior art, etc)makes it the most versatile tool.

provides very
simple tools, as the

look for the

introduce in any
field as Application
number,
Publication,

These tools usuallygive up much noise

Search fields
GPI offers more than 100 different search criteriain the following fields: standard patent bibliographic data
Abstracts
citations (patent literature, non-patent literature -NPL)
International Patent Classification (IPC)
classifications allocated by the EPO (ECLA, ICO)
classifications allocated by national offices simple patent families (documents having exactly the
same priority picture)

Searching the patents
The search window is now displayed. In the query edit zone entermanually a short Boolean query, e.g.
ABEN OR TIEN = laser AND beam AND (IPC = G11B OR H01L)
to retrieve all documents having an English abstract (ABEN) orEnglish title (TIEN)
containing the words "laser" and "beam" limited to IPC classesG11B or H01L, and
click the Search button to run your first search:
Once the search result is displayed, click the Result button to go tothe result .

Search in either title or abstract patents thatconcern the use of urea for cancer treatment ordiagnosis (if no GPI search in European patentapplications microarra* in title or abstract andIPC A61* or C12* or G01N)
How many patent families GPI finds?

What is a patent family
In april of 1998 two polish chemists sent the documentsdescribing their new process for the preparation ofamlodipine benzesulphonate (for hypertension and chronicstable angina) to UPRP.
The documents were received the 9 of april and were later
published as the patent application PL325757A1 According to PCT requirement of filling to them the
application no more than one year after initial filling theyreceived the patent documents the 8th of april of 1999
PCT gave them a very positive ISR so they decided to go
ahead with the patenting process in a few countries wherethe patent received national numbers and codes all of themwith the same applicant, same priority and same IPC codes:AT302187T, AU3061399A, CN1122023C, DE69926704D1....

How GPI calculates families
Any document with the same applicant, IPC
classification and priority date belongs to the
same family.

A personal strategty
Keyword calibration
If you have already a patent application or granted
patent and the task is to look for related patents then
the first search must contain that patent in the resultslist.
Searching through the results list find two, three or
more very representative patents and use them to
calibrate further searches. Further searches must contain all the patents selected
in previous searches by their high representativeness.

Urease to treat cancer
If we are interested in learning everything what we canabout the product patented through PCT asWO2004009112A1- USE OF UREASE FOR INHIBITINGCANCER CELL GROWTH we can try just finding any possiblyrelated patents
WORD = urea* and (cancer* OR tumor* OR tumour*) and(treat* OR diagnos*)
Our patent is in second position what is a good signal
That gives us 341 families. There is a lot to read there, we
can restrict it by adding PRD>20070101 what gives us, howmany families?
What about if instead of limiting the priority date, we justchange urea* by urease
