WIPO PCT Fee Tables Effective 1 September 2026: What Changed for Indian Applicants

Published: 9 October 2026 · Updated: 9 October 2026

Five weeks into the operative date of the latest WIPO PCT Fee Tables (1 September 2026 per wipo.int/export/sites/www/pct/en/docs/fees.pdf), Indian applicants planning a PCT international filing now operate under a verified cost structure anchored to a primary regulator document not cached figures from earlier fee cycles. Every figure below is grep-confirmed verbatim against the 8-page fee tables PDF published by WIPO Geneva.

Five Practical Implications for Indian Applicants

1. India-resident applicants qualify for the 90% reduction. Under PCT Schedule of Fees footnotes 2 and 14, India is among the eligible States whose applicants get a 90% reduction on the international filing fee (including the per-sheet-over-30 fee), the supplementary search handling fee, the handling fee, and exemption from the WIPO International Bureau transmittal fee. Verify the India-specific 90% tier with the registered patent agent at filing footnote language updates on the 1 September cycle.

2. E-filing at WIPO compounds the 90% reduction but the calculation order matters. Start with the base CHF 1,330 international filing fee. First, subtract the fixed e-filing reduction of CHF 100 / CHF 200 / CHF 300 (Items 4(a) / 4(b) / 4(c)) where the application is filed through ePCT in the prescribed electronic form. Only after that subtraction does the 90% reduction under footnotes 2 and 14 apply calculated on the post-e-filing balance, not the gross base. The two reductions do not stack additively. Worked example with the full character-coded Item 4(c) CHF 300 e-filing discount: net international filing fee = (CHF 1,330 − CHF 300) × 10% = CHF 103.

3. Transmittal filings at the Indian Receiving Office (RO/IN) are fee-free in e-form. Under the 1 September 2026 fee tables, RO/IN paper filings are INR 3,500 at the reduced tier (natural persons / startups / small entities / educational institutions footnote 16) and INR 17,600 at the standard tier (footnote 17). E-filings at RO/IN are fee-free (INR 0). The paper-tier fee differential matters only in the rare paper-only scenario.

4. The standard-tier search fee for ISA/IN is INR 10,000 not INR 12,000. Applicants electing ISA/IN (the Indian Patent Office as International Searching Authority) under the 1 September 2026 fee tables pay a search fee of INR 10,000 in the standard tier and INR 2,500 in the reduced tier (natural persons, startups, small entities, and educational institutions) confirmed verbatim in the IN row of the search-fee schedule. The INR 12,000 figure that resurfaces in older Indian PCT-fee guides is the Preliminary Examination Fee under IPEA/IN (PCT Chapter II), not the search fee under ISA/IN. Keep the distinction clean at fee-budgeting time.

5. Keep the WIPO PDF and the IP India First Schedule on separate cadences. The 1 September 2026 WIPO operative date and the 15 March 2024 Patents (Amendment) Rules G.S.R. 200(E) notification do not align. Re-verify every fee figure against the regulator document at filing time, not against a cached blog summary. WIPO PDF: every PCT international-filing event. IP India First Schedule: every Indian-stage fee event Rule 20(4) 31-month national-phase entry, Rule 24B Form 18 Request for Examination, Rule 138 read with Form 4 condonation, Rule 80 online annual renewal.

Frequently Asked Questions About the 1 September 2026 WIPO PCT Fee Tables

Does India qualify for the 90% reduction in PCT fees?

Yes, but the 90% reduction is not additive on top of the gross CHF 1,330 base. Reduction sequence: (1) gross CHF 1,330 → (2) e-filing fixed reduction CHF 100 / CHF 200 / CHF 300 → (3) 90% applied to the post-e-filing balance. Worked example with Item 4(c): (CHF 1,330 − CHF 300) × 10% = CHF 103. Re-verify the calc order with the registered patent agent at filing time.

What is the cheapest PCT international filing route from India in late 2026?

Indian-resident applicant filing electronically through ePCT, electing ISA/IN at the reduced-tier classification, with 90% reduction applied to the post-e-filing balance in the correct calculation order. RO/IN e-filing is fee-free (INR 0); ISA/IN search fee is INR 2,500 reduced-tier; e-filing at WIPO subtracts CHF 100 / 200 / 300 from the gross base. Re-verify the stacking math at filing time the calc-order is the most-misreported line item in older guides.
