Procter & Gamble Company v. Controller of Patents and Designs, Patenting a Registration Process, Drafting a Patent

The LexCampus Weekly Newsletter No. 10

10th March, 2021


This week we look at a decision by the IPAB regarding the filing of a divisional application and the unity of invention presented by the applicant therein. While the Controller had refused to admit the divisional application, the Appellate Board reversed the decision after examining the technicalities of the parent and divisional application under Section 16 of the Patents Act, 1970. This week’s blog discusses the curious case of Kolkata based advocate and entrepreneur Kanishk Sinha who holds the patent for technology related to battery operated eco friendly rickshaws. In a befuddling turn of events the Supreme Court of India stopped the registration of these vehicles across the country and has ruled that Kanishk Sinha is the sole authorised facilitator of such registration. This week, our drafting tips section progresses to the topic of transition words in drafting a patent. We conclude the newsletter with a patent based Q & A answered by Dr. Feroz Ali.

  • In most cases, a combination claim would require one or more words to help make the transition between the body and the preamble of the claim. The most commonly used phrases for transition are “comprising” and “which comprises”.
  • The term “comprising” according to established principles is taken to mean “including the following but not excluding others”.  This leaves the claim open and not closed.


QUESTION: Why is filing a request for examination necessary?


You should understand that patent prosecution is like a game where the burden is on the applicant to make the moves. If the applicant fails to make a move, there are various deeming provisions by which the patent office will assume you’re not interested. And that is the right way to structure it, because you want a right; if you want to right you have to move towards it. So they’ve said, what if a person .. Read more
