Indian patent office governs patent registration process by determining the patent eligibility of an innovation.
Once a patent application is filed with the patent office, patent applicants are required to submit request for early publication of patent application in addition to request for patent examination. Once a patent examination request is filed, the patent office examines the patent application in accordance with patent procedure and provides a patent examination report (patent office action) to the patent applicants.
As per the procedure followed by the Indian Patent Office, the patent specification filed by the patent applicant includes invention details and patent claims. As it is well known, the most important aspect of the patent application are the patent claims because the patent claims define the scope of the invention.
Generally, the patent examiner issues an office action setting forth the basis for rejecting one or more patent claims with respect to prior art / novelty patent search conducted by the patent examiner. The patent applicant responds with amendments in patent claims/ patent drawings and/or arguments, and the examiner issues a next office action, etc. This process continues until the patent application is allowed, abandoned, or appealed.
In accordance with applicable laws and rules, patent applicants are required to submit a detailed response the patent examination report (FER or first examination report) within 6 months of issuance of the first examination report or the office action. A general strategy that can be followed to draft office action response includes preparing submissions for each of the objections raised by the patent examiner. For example, for objections relating to novelty and inventive step (non-obviousness), one of the strategies can be to amend the patent claims by limiting the scope of originally filed claims. This can be done in consultation with a patent attorney, whereby, certain features from the dependent claims (or detailed description) can be added to the independent claims to ensure that the amended claims are novel and inventive as compared to the prior arts (patent and non-patent literature) cited by the patent examiner. Therefore, chances of overcoming such objections get better when novel aspects of the invention are combined with the independent claims.
When a patent application is examined by the patent office, the primary goal of the patent examiner is to determine the patentability of the invention as defined by the patent claims, as described in detail by the patent description, and as illustrated by way of patent drawings. The intention is to ensure that the technology covered by the patent application is new and the subject matter of the patent description and patents claims was not disclosed in public domain before the date of filing of patent application, or before the first priority date of the patent application.
In accordance with the Indian Patents Act, 1970, definition of invention and inventive step include:
Section 2(1) (j) “invention” means a new product or process involving an inventive step and capable of industrial application;
Section 2(1) (ja) “inventive step” means a feature of an invention that involves technical advance as compared to the existing knowledge or having economic significance or both and that makes the invention not obvious to a person skilled in the art;
In essence, the inventive step of the technology to be patented should illustrate technical advancement or economic significance in the subject matter of the patent application as compared to the existing knowledge which is already known to a person skilled in the similar domain.
In Biswanath Prasad Radhey Shyam vs Hindustan Metal Industries Ltd, it was held by the Indian Supreme court that “The expression” does not involve any “inventive step” and its equivalent word “obvious”, have acquired special significance in the terminology of Patent Law. The ‘obviousness’ has to be strictly and objectively judged. For this determination, several forms of the question have been suggested. Was it for Practical Purposes obvious to a skilled worker, in the field concerned, in the state of knowledge existing at the date of the patent to be found in the literature then available to him, that he would or should make the invention the subject of the claim concerned?
To determine Invention Step, the following points should be taken into consideration:
(a) Identify the “person skilled in the art”, i.e. a competent craftsman in same domain or engineer as distinguished from a mere artisan;
(b) Identify the relevant common general knowledge of that person at the priority date of filing the patent application;
(c) Identify the inventive concept of the patent claim in question;
(d) Identify what, if any, differences exist between the matter cited as forming part of the “state of the art” of the technology and the inventive concept of the patent claims.
The invention as claimed in patent specification should meet the criteria that the invention can be made or used in some kind of industry. The word “Industry” broadly refers to having any useful and practical activity while excluding intellectual or aesthetic activity.
Under section 2(1)(ac) of Indian Patents Act, “capable of industrial application”, in relation to an invention, means that the invention is capable of being made or used in an industry.
However, patent claims relating to “Method of playing games” and “computer programming languages” are not considered to be industrially applicable. The detailed description of the patent specification must disclose a practical application and industrial use for the claimed invention wherein a concrete benefit must be derivable directly from the description coupled with common general knowledge.
Therefore, while drafting patent application, writing the advantages of the invention in the last few paragraphs will be helpful to illustrate the industrial applicability of the invention.
While drafting a patent application, writing the detailed description of the patent application includes explaining each and every element of the patent claims. One should note that the patent examiner takes into consideration the whole patent document which is read with patent claims and drawings (if any) to determine patentability of the invention.
‘What’ is the invention and ‘How to perform it’ requirement should be taken care off before submitting the Patent Application before the Indian Patent Office. The complete specification should therefore disclose the invention completely to meet the requirement of the Patents Act and should also enable a person skilled in the art to work the invention without any assistance of the patentee or any further experimentation.
What is the Invention: If the patent application relates to apparatus/system/device in a computer related invention (hardware based inventions), each and every feature of the invention should be described with drawings. However, if the said system/device/apparatus patent claims are worded in such a way that they merely and only comprise of a memory which stores instructions to execute the previously claimed method and a processor to execute these instructions, then this set of claims claiming a system/device /apparatus may be deemed as conventional and may not fulfil the eligibility criteria of patentability.
