The Indian Patents Act 1970 has been amended by Patents Amendment Act, 2005 and Patent Amendment Rules 2006 have been enforced.
Searches on line for both name and subject matter.
Request for Examination : It is now possible to file an Request for Examination for pending Patent Applications filed by you or also for Applications filed by somebody else, provided you can prove your interest in such Patent applications. The Request for examination has to be filed within 48 months from the earliest priority date of the application or from the date of filing the application whichever is earlier.
Convention Country : "Convention Country" now includes a group of countries, union of countries or an inter-governmental organization. This will enable claiming priority from Applications filed under other treaties and conventions, for e.g European Patent Convention.
The Concept of "invention" : The definitions of invention have been enlarged to mean "a new product or process involving an inventive step and capable of industrial application".
Publication : An Application for Patent in India will be publishedon expiry of eighteen months from its priority date, or from the date of filing of application which is earlier. Earlier an Application would be published only after acceptance thereof. This will be in line with the PCT and EPO practice. Therefore, only way publication may be avoided is by withdrawing the Application before the expiry of eighteen months from its priority date.
A request for publication under sub section (2) of section 11(A) shall be made in Form 9 for early publication.
Time for placing the Application in order : The time for placing the Application in order for grant has been twelve months from the date of issuance of first examination report. This will again call for a careful re-docketing by Applicants and their Agents to avoid untimely lapse of an Application.
Publication of all documents : The date of Application, number of application, name and address of the Applicant identifying the application and an abstract will be published on the website of the Indian Patent Office and Official Gazette.
Opposition : The following two grounds of the opposition and revocation have been added:
(a) Investigating infringements and filing actions for infringement, revocation of patents.
(b) Anticipation of the invention by prior knowledge, oral or otherwise, available within any local or indigenous community in any country. The purpose is to protect traditional knowledge. We expect that the burden or establishing these grounds will be rather heavy.
Pre-grant opposition under Section 25 (1) can be filed by any person at any time before the grant of the Patent (i.e. in pending application) without any fee.
Post grant opposition under Section 25(2) can be filed at any time after the grant of patent but before the expiry of a period of one year from thte date of publication of grant of a patent, any interested person may give notice of opposition to theController of Patents on Form-7 along with prescribed official fee.
Restoration : The request fot Restoration of lapsed patents can be filed within a period of eighteen months from the date on which the patent ceased to have effect. Statement and Evidence for support of the failure of renewal fees has to be filed on Form 15 along with prescribed official fee.
Reversal of burden of proof : In special cases where the alleged infringement is for a process for the manufacture of a new product, the burden of proof may be on the defendant to establish that its process does not constitute an infringement. Hitherto, the burden of proof on all classes of infringement cases was always on the plantiff.
Term of Patent : The term of the Patent is now twenty years from the date of filing of the application in Paris Convention and in the International application the term start from the International filing date.
Statement regarding the working of the patent Invention on commercial working scale in India Under Section 146(2)
The statement regarding the working of the patented invention has to be furnished by every patentee and every license on Form 27 in respect of every calendar year within three months of the end of each year.
Appellate Board : An Intellectual Property Appellate Board has been established. An Applicant can file an Appeal in the IPAB against any decision, order or direction made or issued under the said Act by the Central Government or Controller of Patents under Section 15, 16, 17, 18, 19 [Section 20, sub-section (4) of Section 25, Section 28], Section 51, 54, 57, 60, 61, 63, 66, Sub- Section [3] of Section 69, 78, sub-Section [1] to [5] of Section 84, 85, 88, 91, 92and 94.
