Patent Act_16

Does grant of a patent in one country affect its grant or refusal in another country?

Each country is free to grant or refuse a patent on the bases of scrutiny by its patent office. This means that granting a patent in one country of the Union does not force other countries to grant the patent for the same invention. Also, the refusal of the patent in one country does not mean that it will be terminated in all the countries.

Patent Act_15

Is a patent granted in one country enforceable in other countries?

No. There is nothing like a global patent or a world patent. Patent rights are essentially territorial in nature and are protected only in a country (or countries) which,has (have) granted these rights. In other words,-for obtaining patent rights in different countries one has to submit patent applications in all the countries of interest for grant of patents. This would entail payment of official fees and associated expenses, like the attorney fees, essential for obtaining patent rights in each country. However, there are some regional systems where by filing one application one could simultaneously obtain patents in the member countries of a regional system; European Patent Office is an example of a similar system.

Patent Act_14

What is the distinction between a patented invention and know how?

The law does not require that the information disclosed in the patent specification be sufficient for commercial exploitation of the invention. Thus, patent usually will not disclose sufficient information for commercialization. Know how on the other hand, covers all information necessary to commercialize the invention e.g. setting up a production plant. Such information would include, for example, details of the production methods, the design drawings etc. It is this know how which is traded while transferring technology. Know how is always kept as a trade secret and not shared with public. Know how is not protected through patents as most of it is non-patentable matter and one does not take patent on the remaining parts to avoid public disclosure. A know how developed around an existing patent and commercialized subsequently may be an infringement of the patent unless the patentee has agreed to commercialization on mutually agreed terms.

Patent Act_13

What is opposition under the Indian Patents Act 1970?

After the Patent Office has examined an application and found it in order forgrant of a patent, it publishes the title pf the invention, name of the inventor(s) and the applicant(s), abstract of the invention, drawings and claims in the Gazette of India, Part III Section 2, for interested parties to oppose the grant of the patent. An application for opposition may be filed at the concerned Patent Office branch within four months of the date of the issue of the concerned gazette. An extension of one month is possible; a request for extension has to be made within the first four months. Typed or photocopies of the specification together with photocopies of the drawings, if any, can be obtained from the Patent Office, Calcutta or the concerned branch office on payment of the prescribed fees. One would like to oppose if the idea of the accepted application infringes upon one's invention/existing patent, if the coverage of the proposed patent is very wide which may be detrimental to one's research or if the idea is not novel and so on.
