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.

Exercise

Try to find a patent (the first if it is possible) of

a denaturat stable homo-oligomeric protein

composed of 12 monomers that remains

stable up to 110C and it is also detergent andprotease resistant

A small exercise

In patentscope, go to combination fields, writedown in the Front page field urea*, in the nextfield select in the combo boxes AND English

abstract, then write cancer OR tumor OR tumour How many results are there?

How many of those results use the word tumour?

And, how many tumor?

Which companies work for the five most prolificinventors?

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


20/39

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.

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)


31/39

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 .

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....


36/39

How GPI calculates families

Any document with the same applicant, IPC

classification and priority date belongs to the

same family.


37/39

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.


38/39

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
