The Indian Patent Scenario


A large number of patent filings in India belong to this category. Many companies both Indian as well as international files patent for process/method, machinery/ device/apparatus etc. 


Apart from basic criteria of patentability viz. Novelty, Inventive step and Industrial applicability which are governed by Section 2 of the Indian Patent Act, the relevant provision that impact the inventions under this category is section 3(c) and section 3 (f). Section 3(c) states that “the mere discovery of a scientific principle or the formulation of an abstract theory or discovery of any living thing or non-living substances occurring in nature” is not patentable. 


For example, a method of increasing the cooling effect in a heat exchanger by increasing the length of the coolant tubes is not patentable but a heat exchanger with coolant tubes arranged in a zigzag manner instead of straight line may be patentable.


Section 3(f) states that “the mere arrangement or re-arrangement or duplication of known devices each functioning independently of one another in a known way” is not patentable, i.e. in order to be patentable, an improvement on something known before or a combination of different matters already known, should be something more than a mere workshop improvement. 


Current scenario in India


With the development in national laws, many mechanical companies have developed their base in India for the local manufacturing and export of the machinery at cheaper costs. The companies have actively enhanced their IP filings in India due to various new reforms in nation. The concept of patentability became more clear to the companies with the case of Lallubhai Chakubhai Vs. Chimanlal and Co. where the Hon’ble Court held that if the result produced by the combination is either a new article or a better or cheaper article than before, the combination may afford patentable subject-matter. 


Also, in Rampratap v. Bhabha Atomic Research Center, the Court held that when two or more features of an apparatus or device are known, and they are juxtaposed without any interdependence on their functioning, they should be held to have been already known, for example an umbrella with fan, bucket fitted with torch etc.
