Rule 45 of the Patents Rules, 2003
Omitted provision
An omitted rule from the chapter that implemented India's treaty transition period, during which product patent applications were filed but held.
Official legal text
When a provision is removed, the rest of the statute is not renumbered. The number stays in place, marked as omitted, so that everything after it keeps its familiar citation. That is why this number still appears, and why older files, textbooks and judgments continue to refer to it.
Treat this page as a guide. The provision as officially published, along with the Gazette notifications that apply to it, remains the governing text and overrides any simplification here.
What this rule requires, step by step
India's transitional arrangement had two halves. One half allowed applications for pharmaceutical and agrochemical products to be filed from the beginning of 1995 and kept aside until the country was ready to examine them. The other half offered a narrow selling right in the meantime. The chapter of the Patents Rules containing this number belonged to the second half, and it is the reason the Rules of 2003 needed a chapter that no longer appears in them.
The arrangement came from India's obligations as a developing country under the international agreement on trade-related aspects of intellectual property rights, which allowed a phase-in period for product patents in fields not previously covered. India used the full period. The provisions were introduced in 1999 with retrospective effect from the start of 1995, carried into the 2003 Rules, and then omitted after the Patents (Amendment) Act, 2005 completed the transition. Nothing in that history restricts a filing made today, but it explains why applications with 1995 to 2004 priority dates in these fields have unusual histories on the Indian file.
Why this rule matters
Anyone working with Indian patent families that have priority dates between 1995 and 2005 in pharmaceuticals or agrochemicals.
When reading the file history of an application held during the transition, or when studying India's treaty compliance.
Nothing today. It carried part of the procedure India used to meet its transitional obligations.
Puzzlement at long gaps in older Indian file histories, and misreading them as inactivity by the applicant.
How it works in practice
A file history with a ten-year gap
A patent analyst in Ahmedabad was asked to review an Indian patent family for a licensing target. The earliest Indian application in the family had been filed in 1997 but showed almost no activity until 2005, when examination suddenly began. She initially flagged it as an abandoned filing revived by unusual means. Her senior colleague explained the transition. Applications for pharmaceutical and agrochemical products filed from 1995 were held for later examination while India phased in product patents, and were taken up only once the 2005 amendment came into force. The gap was not neglect; it was the law. She rewrote her note, explained the transitional background in two sentences, and recalculated the expiry date as twenty years from the original Indian filing date. The client, an American licensee, had assumed the patent had years longer to run and adjusted its offer accordingly.
Simplified illustration only. Actual legal outcomes depend on the facts.
Key points to remember
- India used a treaty phase-in period before granting product patents for medicines and agricultural chemicals.
- Applications filed from 1995 in these fields were held and examined only after the 2005 amendment.
- The rules supporting the interim selling right were omitted once the transition was complete.
Connected provisions
A rule is subordinate legislation. It is made by the Central Government under a rule-making power in the Act and is amended by notification rather than by Parliament. The parent sections are listed on their own so that the source and the procedure are never confused.
Forms, deadlines and fees
Where a fee is payable under this provision, the figure comes from the First Schedule. Categories of applicant are charged at different rates, and electronic filing is treated differently from paper filing, so an accurate number can only come from the Schedule in force on the day you file. How Indian patent fees work.
Related judgments
Case summaries are published only after a qualified reviewer has checked the judgment, the citation and the way the holding is described. Nothing has cleared that review for this provision yet, so nothing is listed here. We would rather show no case note than one that misstates what a court decided. How case notes are prepared.
Questions people ask about Rule 45
Why do some Indian patent applications from the 1990s show no activity for years?
Because of the transition to product patents. Applications for pharmaceutical and agricultural chemical products could be filed in India from the beginning of 1995 but were held aside rather than examined, since patents for those products were not yet available. They were taken up for examination after the Patents (Amendment) Act 2005 came into force. A long quiet period in such a file usually reflects that statutory holding arrangement rather than any inaction by the applicant.
What was India's TRIPS transition period for patents?
As a developing country, India was allowed time to extend patent protection to product inventions in fields it had previously excluded, including medicines and agricultural chemicals. During that period it had to accept and hold applications and offer a limited interim right. India completed the transition at the start of 2005, when product patents in those fields became available. The interim arrangement and the rules serving it were then removed from the Act and the Rules.
