Patent Filing Services in Delhi for enterprises, institutions and NCR innovators.

The Delhi branch of the Indian Patent Office has territorial jurisdiction over applicants resident in Delhi, Haryana, Uttar Pradesh, Punjab, Rajasthan, Uttarakhand, Himachal Pradesh, Jammu & Kashmir, Chandigarh, and the north-eastern states. It is the busiest branch office in the country.

Yes. Recognised educational institutions qualify for a reduced official fee category at the Indian Patent Office, substantially lowering filing, examination, and renewal costs compared with large-entity rates.

Ownership is determined by the institution's IP policy and the sponsored-research agreement. Typically the institution owns the filing with a revenue-share to inventors, and sponsor rights are defined contractually. We review the agreement chain before filing so ownership is unambiguous at the point of licensing.

You should. Publication before filing generally destroys novelty. The standard approach is to file a provisional application before submitting the paper, then file the complete specification within 12 months while the research continues.

Yes. We work with companies in Delhi, Gurgaon, Noida, Faridabad, and Ghaziabad, with dedicated pages for Noida and Gurgaon. Filing is electronic and all NCR applicants fall under the same Delhi patent office jurisdiction.

Patent filing costs in Delhi have two components: statutory Indian Patent Office fees and professional fees. Official fees for an e-filed application start at ₹1,600 for an individual, startup, small entity, or educational institution and ₹8,000 for a large entity, with additional fees for extra claims, extra pages, examination request, and expedited examination. Professional fees depend on the technical complexity of the invention and the scope of work — patentability search, drafting, filing, and prosecution are usually quoted separately. Hashi IP Solutions provides a fixed, itemised quote after a confidential technical discussion.

A provisional application can be prepared and filed in 5–10 working days; a complete specification typically takes 2–4 weeks depending on complexity. Grant timelines are longer: after a Request for Examination, a First Examination Report is generally issued within 12–30 months, and grant commonly follows 2–4 years from filing. Expedited examination — available to startups, small entities, female applicants, and applicants choosing India as the ISA/IPEA — can reduce this to roughly 12–18 months.

Yes. DPIIT-recognised startups can file patents in India and receive an 80% reduction in official patent office fees, access to expedited examination, and facilitator support under the Startups Intellectual Property Protection (SIPP) scheme. A startup can file a provisional application early to secure a priority date and file the complete specification within 12 months.

Software is patentable in India when the claimed invention demonstrates a technical effect or technical contribution beyond a computer program per se, which is excluded under Section 3(k) of the Patents Act. Inventions involving AI models, signal processing, data-processing architectures, security, memory management, or hardware-linked functionality are regularly granted when the specification and claims are drafted around the underlying technical problem and solution.

A provisional application is an early filing that describes the invention and secures a priority date without requiring claims in final form. You then have 12 months to file the complete specification. It is useful when the invention is still evolving, when funding or a publication deadline is near, or when you want to establish priority before disclosure to investors or partners.

A provisional specification describes the invention and secures a priority date; a complete specification fully discloses the invention and defines the legal scope of protection through claims. Only a complete specification can proceed to examination and grant. The complete specification must be filed within 12 months of the provisional or the application is deemed abandoned.

A patentability search is strongly recommended but not legally mandatory. It identifies closely related prior art, indicates whether the invention is likely to be novel and inventive, and shapes how the claims are drafted. A search costs a fraction of the full filing and prosecution budget and often prevents spending on applications with little chance of grant.

Ownership depends on the employment agreement and the assignment executed. In India, an invention made by an employee in the course of employment is typically assigned to the employer through an express assignment or an IP clause in the employment contract. Inventors must still be named on the application; assignment transfers rights, not inventorship.

Applicants resident in India must either first file in India and wait six weeks, or obtain a Foreign Filing Licence under Section 39 before filing abroad. From there the two main routes are a PCT international application — which preserves the option to enter roughly 150+ countries for up to 30/31 months — and direct Paris Convention filings within 12 months of the priority date in individual jurisdictions such as the US, EPO, Japan, China, and Korea.

The First Examination Report is the patent office's first substantive communication, raising objections on novelty, inventive step, subject-matter eligibility, clarity, and formalities. A complete response must be filed within six months of the FER, extendable by three months. The response typically combines claim amendments with technical and legal arguments distinguishing the cited prior art.

Yes. Every discussion with Hashi IP Solutions is confidential, NDAs are signed on request before any technical disclosure, and files are handled under access-controlled, ISO-aligned information-security practices. Indian patent applications are published 18 months from the priority date, or earlier if early publication is requested.

You need a technical description of the invention (including drawings or diagrams), inventor and applicant details with addresses and nationality, proof of entity status for fee concessions (such as a DPIIT startup certificate or Udyam registration), and signed forms — Form 1 (application), Form 2 (specification), Form 3 (foreign filing statement), Form 5 (declaration of inventorship, for complete filings), and Form 26 (power of attorney).

Public disclosure before filing generally destroys novelty. India provides a narrow 12-month grace period under Sections 29–34 for specific situations such as disclosure at a government-notified exhibition, a paper read before a learned society, or unauthorised disclosure. Relying on these exceptions is risky — filing at least a provisional application before any disclosure is far safer.

Hashi IP uses AI to accelerate prior art discovery, map claim scope against cited references, generate embodiment variations, and run consistency and support checks across the specification. Every specification and claim set is authored, reviewed, and signed off by qualified patent professionals — AI compresses the research and iteration cycle, it does not replace professional judgement.

Hashi IP Solutions combines domain-qualified technical specialists with AI-native patent workflows across drafting, prior art and patentability search, filing, prosecution, and analytics. Clients receive a single accountable team, transparent fixed-fee scoping, fast turnaround, and filings drafted for enforceability and commercial leverage rather than volume.
