Patent Law

At Fidus Law Chambers, we provide a full spectrum of patent-related services across industries, combining deep technical expertise with sophisticated legal insight. As one of the leading Patent Law Firms in India, we assist clients throughout the entire patent lifecycle—from innovation capture and filing, to litigation, enforcement, and commercialization. Our team of seasoned Patent Lawyers in India is known for delivering high-quality work that is both legally robust and commercially valuable.

Our patent practice is anchored in four key verticals:

1. Search & Analytics

   We offer a comprehensive range of search and patent analytics services, including:

   • Freedom to Operate (FTO) searches
   • Patent validity/invalidity analyses
   • Product clearance assessments
   • White space analysis
   • Patent mapping and landscaping
   • Risk mitigation strategies

   These services are designed to help clients make informed R&D and business decisions while minimizing legal exposure and identifying opportunities for innovation.

2. Patent Protection & Prosecution

   We specialize in drafting and filing patent applications that are technically sound and globally enforceable. Our patent attorneys are also qualified lawyers, enabling us to bring a dual lens to every invention—ensuring both legal defensibility and strategic alignment. Our services include:

   • Drafting and filing of patent applications with the Indian Patent Office
   • Filing of PCT applications and managing national phase entries across jurisdictions
   • Filing of Form 27 for compliance with working requirements in India
   • Coordination with a trusted network of foreign associates to prosecute patents globally
   • Advising on patentability, prior art, and patent scope

   We serve as a single point of contact for Indian clients seeking patent protection overseas, and for global companies navigating the Indian patent system.

3. Patent Enforcement & Litigation

   Our team of Patent Lawyers in India is highly regarded for its expertise in enforcement and contentious matters. We represent clients in high-stakes patent litigation before courts, including the Delhi High Court and other commercial courts across the country. Our enforcement services include:

   • Filing and defending pre-grant and post-grant oppositions, revocations, and appeals before the Indian Patent Office
   • Litigation support including expert witness coordination and complex trial management
   • Criminal enforcement in collaboration with investigative agencies
   • Strategic counsel on Standard Essential Patents (SEPs) and FRAND licensing obligations

   We have successfully advised both patent holders and implementers in SEP disputes and FRAND-related negotiations, helping clients balance exclusivity with compliance in complex, tech-heavy sectors.

4. Patent Commercialization

   We assist clients in unlocking the commercial value of their innovations through:

   • Drafting and negotiating license agreements and assignments
   • Structuring technology transfer agreements
   • Conducting patent audits to identify portfolio strengths, underutilized assets, and monetization opportunities

Whether a client is preparing for a strategic acquisition, joint venture, or R&D collaboration, we ensure their patent assets are leveraged to maximum advantage. Our expertise spans the full lifecycle of patent protection—including prior art searches, drafting and filing patent applications, clearance and freedom-to-operate opinions, portfolio advisory, and high-stakes litigation. With a multidisciplinary team well-versed in both technical and legal domains, we deliver strategic, end-to-end patent solutions tailored to our clients’ commercial goals.
