Up until now the patent office website carried only the patent specification, abstract and the publication dates of the application, filing etc. The latest additions to the IPAIRS system will be the First Examination Reports (FER) and the details of the Patent Register. With these additions the Patent Office has basically ensured that almost the entire file wrapper is available on the website. I would have provided more details on the new system except that it seems to be facing some preliminary glitches.
The publication of such information on the website greatly eases the process of retreiving information from the patent office. Prior to this information being put up on the website a patentee would have to necessarily end his agent to the Patent Office to carry out a physical inspection of the files after which he would have to apply for photocopies. By putting up this information on the website the CGPDTM has ensured that patentees and the general public can access information related to their patents in a cost-efficient manner.
We will get you more details on the website once it is fully functional.
