Patent Office of the Republic of Poland
I. GENERAL OVERVIEW OF RECENT DEVELOPMENTS IN PATENT INFORMATION ACTIVITIES CARRIED OUT BY THE OFFICE
Outline of main policies and plans aimed at development of patent information activities and expected time frames for their realization
The Patent Office of the Republic of Poland aims at development of patent information activities within cooperation with PATLIB centres, European Patent Office, World Intellectual Property Organisation and the European Commission. Within the above mentioned cooperation the Office implements new services as well as adapts and improves the existing services and tools provided by national intellectual property offices.
Main policies and plans of the Office include among others activities aimed at supporting innovativeness of SMEs, commercialisation of intellectual property and development of entrepreneurship. Those activities are implemented by improving business skills in patent information usage, especially in creating strategies of enterprises, creating cooperation platform between business and scientific environment as well as platform for exchanging experience and knowledge.
New projects launched or resumed this year in the context of the policies and plans mentioned above, short description: aims, partners, tasks
In 2015 the Office in collaboration with WIPO started implementation of a two-year scientific-research project “Intellectual Property and Socio-Economic Development”. The aim of the project is to analyse the relation between intellectual property in a given industry sector and socio-economic development of the country. The results of the project may have impact on more conscious development of national policy in the scope of intellectual property on both central and local level. Taking into account current trends in scientific and economic development in Poland, the health care sector is to be analysed. The methodology of research is based mainly on statistical and comparative analyses.
In 2015 PPO was active in the field of e-administration services, taking part in the development of functionalities related to the use of new version of governmental Electronic Platform of Public Administration Services (ePUAP2). PPO has dealt with maintaining of the existing forms in terms of their functionality and reliability and has refined the process of exchanging documents between ePUAP2 and Electronic Document Management system (EZD). PPO has also completed additional tasks related to migration of services between production and test instances of ePUAP2 platform.
Electronic Document Management System (EZD) based on Alfresco Community Edition software was developed and adapted to meet the needs of the PPO.
PPO has carried out the development of the Register Plus system. The scope of data presented has been extended for national, EP and SPC patents and utility models.
Under the Innovative Economy Programme project, the PPO has continued the development of main search engine of industrial property items, based on the SharePoint 2013.
PPO launched new version of publication (searching) server “Lista Rzeczników Patentowych” [Patent Attorneys List], containing list of patent attorneys. Adjustments to the data structure and adaptation of the system to the current legislation were made.
PPO continuously updated the versions of IPC, Nice, Vienna, Locarno and Eurolocarno classifications in Polish, English and French.
PPO conducted go-live of a new intranet on SharePoint 2013: new versions of personal pages, updating and ordering official documents, launching the search of documents and adding other new functionalities.
Main areas of patent information activities and related information and communication technology (ICT) practices which were in the focus of attention last year
The RegisterPlus software application for patents was further developed and enhanced in 2015. The quality of data was improved and a wider range of presented data was introduced.
As the continuation of work on the main search engine of industrial property items in the year 2015 there were introduced dozens of amendments requested by users, aimed at improving the functionality of the search engine. It is linked to other search systems, which are in the portfolio of the Office (Publication Server, Register Plus, etc.).
Statistics: changes in terms of application filings and grants with respect to previous year; trends or areas experiencing rapid changes
Filings to the Office are increasingly more often preceded by searches in the electronic collections than in the paper holdings.
In 2015, the PPO received 4,773 patent applications under the national procedure, out of which 4,674 were filed by domestic applicants and 99 by foreign applicants.
42 applications filed under the Patent Cooperation Treaty entered the phase of examination carried out by the Office (so-called national phase).
Under the international procedure, as the receiving Office, the PPO received from domestic applicants 305 patent applications under the PCT procedure and 239 European patent applications with the aim of seeking protection abroad.
In 2015, the Office received from foreign applicants 60 applications for the grant of supplementary right of protection for medicinal products and plant protection products in order to protect rights under Supplementary Protection Certificate (SPC).

VII. OTHER RELATED MATTERS
1.Classification is allotting one or more classification symbols (e.g., IPC symbols) to a patent application, either before or during search and examination, which symbols are then published with the patent application.
2. Preclassification is allotting an initial broad classification symbol (e.g., IPC class or subclass, or administrative unit) to a patent application, using human or automated means for internal administrative purposes (e.g., routing an application to the appropriate examiner). Usually preclassification is applied by the administration of an office.
3. Reclassification is the reconsideration and usually the replacement of one or more previously allotted classification symbols to a patent document, following a revision and the entry into force of a new version of the Classification system (e.g., the IPC). The new symbols are available on patent databases.
