India is currently witnessing an innovation renaissance. In 2023 alone, patent filings skyrocketed past 64,000, accompanied by a surge in trademark and industrial de­sign registrations. This is not merely a statistical spike; it is a definitive signal that India’s researchers, corporations, and creators are no longer just inventing, they are strategi­cally fortifying their intellectual assets.

In this high-velocity landscape, the difference between a vulnerable idea and a market-dominating asset often comes down to one factor: superior legal counsel.

Standing at the vanguard of this shift is Hasan and Singh. Since its establishment in Hyderabad in 2011, the firm has evolved from a regional challenger into a national heavyweight, with a footprint now spanning Delhi, Chennai, Kolkata, and Mumbai. Today, they are not just service providers; they are the strategic architects behind some of the most complex IP portfolios in the country.

They undertake the filing and prosecution of patents in India, and also handle global filings and PCT filings on behalf of clients whose work extends beyond domestic level.

A Holistic Shield for Innovation

In a market often fragmented by niche specialists, Hasan and Singh has carved a reputation for mastery across the full spectrum of intellectual property. They don't just file patents; they construct comprehensive legal shields. The firm expertly navigates the intricate corridors of global IP law, handling everything from domestic prosecution to complex international PCT filings.

"In addition to patents, we handle trademarks, industrial-design registrations, copyrights, semiconductor layout-design concerns, and domain-name issues," says Vatsala Singh Hasan, Co-Managing Partner, Hasan and Singh. "These services are the backbone of our daily operation, designed to support clients in passing all the milestones of the IP process".

Engineering Legal Victory

What truly distinguishes Hasan and Singh is their technical DNA. Modern invention lives at the intersection of disciplines, and legal advice must match that complexity. The firm’s roster includes experts capable of deconstructing innovations in high-stakes fields like chemistry, pharmaceuticals, biotechnology, life sciences, mechanical engineering, electrical and electronics, computer science, artificial intelligence, robotics, biomedical engineering, and renewable-energy fields.

This range reflects the variety seen in India’s innovation landscape today, where new ideas often come from overlapping disciplines. This ensures that every legal strategy is rooted in a profound understanding of the underlying science.

Beyond securing the initial grant, the firm serves as a vigilant guardian of commercial value by implementing a rigorous portfolio management strategy. This includes conducting freedom-to-operate analyses to eliminate infringement risks prior to product launches, performing due diligence reviews to validate asset value during mergers and acquisitions, and structuring technology transfer agreements that transform innovative concepts into sustainable revenue.

Understanding Innovation in a Crowded Field

As the number of creators in the IP space grows every year, the necessity to file carefully and support the filing with robust legal advice grows. The increase in patents, trademarks and designs in India is a real opportunity but it also presents challenges in terms of prior art, technicality and speed of legal review.

A firm like Hasan and Singh becomes important in such a space, not because of big claims but because the work demands accuracy and a clear reading of both science and statute.

Clients across sectors now look for partners who understand the substance of their innovation as well as the laws that protect it. By working across so many technical fields, Hasan and Singh offer a grounded form of support that aligns with how ideas are being developed today.

This makes the firm part of the wider network that keeps India’s innovation engine moving, even if its role is often behind the scenes.

As India continues to strengthen its position in the global IP landscape, the quiet, detailed work of firms like Hasan and Singh helps turn creative ambition into protected reality.

It is steady work, built on clarity and depth, and it shapes how ideas travel from research tables and workshops into the world with the security they need to grow.

Their enforcement practice is formidable, managing high-profile oppositions, revocations, and anti-counterfeiting raids. Yet, their philosophy remains client-centric—prioritizing resolution over billable hours.

"This mix of preventive work and legal action keeps clients from needing multiple service providers", explains Afzal Hasan, Managing Partner, Hasan and Singh. "It offers them a single firm with a consistent, holistic understanding of their portfolio, ensuring that their defense strategy is as robust as their filing strategy."

Their curated network of global associates allows for synchronized prosecution and enforcement across borders.
