The journey pertaining to Guidelines for Examination of Computer Related Inventions (herein CRI) has been both time-consuming as well as riddled with lot of amendments. In light of several remarks and comments from numerous stakeholder’s and further sessions with the Indian Patent Office, revised guidelines pertaining to examination of CRIs has been published on the 30th of June, 2017  which are breather after a long dry spell.

Item 1.3 of the amended guidelines states:

“The objective is to bring out clarity in terms of exclusions under Section 3(k) to allow eligible applications of patents relating to CRIs be examined speedily”.

The major highlight in the guidelines is deletion of the concept of “novel hardware”.

Summarized below are several revisions executed by the Indian Patent Office for Computer Related Inventions in several categories.

A.    Test of Patentability

For novelty, inventive step (Obviousness) and industrial applicability the amended guidelines completely rely on the Manual of Patent office practice and procedure.

B. Sufficiency of Disclosure - It is a mandate to specify “what” is the invention and “how‟ to perform it. For computer related inventions (CRIs), there are requirements laid down and considered as fulfilled if the following are addressed:

  • every feature of the invention described with suitable illustrative drawings;
  • if the invention relates to “method”, the necessary sequence of steps shall clearly be described with the help of the flowcharts;
  • working relationship of different components together with connectivity shall be described;
  • desired result/output or the outcome of the invention as envisaged in the specification; and
  • best mode of performing and/or use of the invention with suitable illustrations.

B. The Notoroius - Section 3(k)

The guidelines also state to be overriding the chapter of Patent Manual containing provisions pertaining to section 3(k) of the Patent Act , 1970

The rules comments on certain provisions of Section 3(k) and clarify the following;

Mathematical Method: The rules read that the mere presence of a mathematical formula in a claim, to clearly specify the scope of protection being sought in an invention, may not necessarily render it to be a “mathematical method” claim.

Business Method: Herein in relation to business methods, there is a significant improvement, wherein it is stated that mere presence of the words such as “enterprise”, “business”, “business rules”, “supply-chain”, “order”, “sales”, “transactions”, “commerce”, “payment” etc. in the claims may not lead to conclusion of an invention being just a “Business Method”.

Algorithm and Computer Programme per se: Computer programs are claimed in the form of algorithms as method claims or system claims with some “means” indicating the functions of flow charts or process steps. While establishing patentability, the focus should be on the underlying substance of the invention and not on the particular form in which it is claimed.

However, it has been clarified that if in substance, the claim, taken as whole, does not fall in any of the aforesaid excluded categories, the patent should not be denied.

Further, the exclusion of computer programs should not be avoided merely by camouflaging the substance of the claim by its wordings.


It is believed that the revised guidelines implemented will be useful to applicants and patent practitioners alike and lead to the acceptance of a wider range of patents in the field of CRIs. On a wider spectrum, there may also be an acute decrease in the number of patent litigation stalling the progress of many companies that have their base in software.

The rules appear to indicate that the Indian Patent Office has taken a more favorable approach to the allowability of CRIs as compared to the past.

As a whole after a long wait and patience, theses improvisations have brought in a ‘NEW DAY’ for the software fraternity.
