Disclaimers - A credible way of amendment in patent claims and specification
By Dr. P. Mahalakshmi and T. Srinivasan
One of the permissible ways of amendments to claims and/or specification is to incorporate suitable disclaimers during the patent prosecution and at the post grant stage. The article in this issue of IPR Amicus aims to bring down the perspectives of the use of disclaimers as a provision to amend claims and/or specification. It focusses on provisions available under Section 59 of the Patents Act, 1970 and a glimpse on such provisions in major jurisdictions such as US and EU that are of greater interest. According to the authors, disclaimers shall be allowed provided they comply with the requirements pertaining to patentability, clarity, conciseness, support and sufficiency as set forth in each of the jurisdiction. They also state that the use of disclaimers is not forbidden but the disclaimers need to be prudently used to satisfactorily protect the invention and to hold a valid patent.
