Understanding the Patent Examination Process in India {#patent-examination-process}

The patent application process India begins with filing Form 1 and specification via the IPO's e-filing portal. After publication (18 months post-filing), request examination using Form 18 within 48 months. The Controller issues an FER outlining objections, typically within 2-4 years, though delays hit 14,756 FERs in FY 2024-25 amid backlog.

Respond within 6 months (extendable by 3), proposing amendments under Section 59. Hearings follow if needed, leading to grant, refusal, or appeal to IPAB. In FY 2024-25, examination slowdowns affected MSMEs, emphasizing early action. Consult the best patent company in India for compliance.

Top 5 Common Patent Rejection Reasons in India {#common-reasons}

IPO data reveals predictable hurdles. Here's an inverted pyramid of the most frequent, drawn from 3,203 rejections for non-patentability:

  1. Lack of Novelty/Inventive Step (Section 2(1)(j)/(ja)): 77% of cases; invention not new or obvious.
  2. Section 3 Exclusions: 65%, especially 3(d) (efficacy), 3(k) (CRIs).
  3. Insufficient Disclosure/Clarity (Section 10): Vague claims/specs.

Detailed Strategies to Overcome Each Objection {#overcome-strategies}

1. Tackling Lack of Novelty and Inventive Step

Examiners cite prior art (D1/D2) claiming anticipation or obviousness. Overcome by: Mapping distinctions claim-by-claim, highlighting technical effects (e.g., 20% efficiency gain). Argue inventive step via problem-solution approach: state problem, closest prior art, jump to invention.

Example Response Snippet: "Claim 1 differs from D1 by [feature X], achieving [effect Y], non-obvious per CRI Guidelines 2025." Amend to dependent claims. Success rate rises 40% with data.

2. Navigating Section 3 Exclusions

Section 3(d) rejects "mere new forms" without enhanced efficacy; 3(k) bars business methods/software sans technical effect. Overcome by: Demonstrate "therapeutic efficacy" via trials (pharma) or hardware integration (software). Cite Fermentation Products (2009) for 3(d).

Checklist:

  • Provide comparative data vs. known substance.
  • Emphasize synergy in combinations.
  • For 3(k): Link to technical field like "AI on edge devices".

3. Fixing Insufficient Disclosure and Clarity

Claims too broad/vague under Section 10(5). Overcome by: Amend for support in spec, use "comprising" transitions. Submit affidavits/experiments. Delhi HC ruled no new grounds at refusal.

4. Countering Prior Art Anticipation

D1 fully discloses? Overcome by: Disclose differences, mosaic arguments (no single D anticipates). Search Espacenet/Google Patents pre-filing.

5. Resolving Formal Defects

PoA/stamp duty lapses. Overcome by: File Form 26/28 promptly; condone delays under Rule 138.
