IPR Lawyer Kolkata Trademark Patent

A trademark is a distinctive sign — a word, logo, symbol, slogan, or combination — that identifies your goods or services and distinguishes them from those of competitors. Trademark registration under the Trade Marks Act, 1999, gives the proprietor the exclusive right to use the mark in relation to the goods/services for which it is registered and the right to sue for infringement. The registration process involves: (1) Trademark search — checking the Trademark Registry database to ensure no identical or deceptively similar mark is already registered for the same class of goods/services. (2) Filing the application with the Trade Marks Registry (Kolkata has a Trade Marks Registry office). (3) Examination and examination report — the Registrar examines the application for absolute and relative grounds for refusal. (4) Publication in the Trade Marks Journal — the mark is published, and third parties have four months to oppose registration. (5) Registration and issuance of the registration certificate. The entire process takes 12-18 months if unopposed. Trademark registration is valid for ten years and renewable indefinitely. The ™ symbol can be used once the application is filed; the ® symbol can be used only after registration. Advocate Panchanand Shaw handles the entire trademark lifecycle — search, filing, examination responses, opposition proceedings, renewal, and infringement litigation.

A patent is an exclusive right granted for an invention — a product or process that provides a new way of doing something or offers a new technical solution to a problem. Under the Patents Act, 1970, a patentable invention must be: novel (not known to the public before the date of filing), involve an inventive step (not obvious to a person skilled in the art), and capable of industrial application. The patent filing process involves: (1) Prior art search to establish novelty. (2) Drafting the patent specification — a detailed description of the invention with claims defining the scope of protection. (3) Filing the application with the Indian Patent Office (the Kolkata Patent Office serves the eastern region). (4) Publication after 18 months (or earlier on request). (5) Request for examination within 48 months of filing. (6) Responding to examination reports (First Examination Report/FER). (7) Grant of patent. Patent protection lasts for 20 years from the filing date. Advocates and patent agents work together in India — patent drafting and prosecution (before the Patent Office) are handled by registered patent agents, while patent litigation is handled by IPR lawyers. Advocate Panchanand Shaw collaborates with qualified patent agents to provide end-to-end patent services, from filing through enforcement and licensing.

Copyright protects original literary, dramatic, musical, and artistic works, cinematograph films, and sound recordings. Under the Copyright Act, 1957, copyright subsists automatically upon the creation of the work — registration is not mandatory for protection. However, registration with the Copyright Office serves as prima facie evidence of ownership in legal proceedings. Copyright gives the owner the exclusive right to reproduce, distribute, perform, communicate to the public, and adapt the work. The term of protection is the author's lifetime plus 60 years. Common copyright matters handled by Advocate Panchanand Shaw include: copyright registration for books, articles, software code, marketing materials, photographs, and music; copyright infringement litigation for unauthorised reproduction or distribution; licensing and assignment agreements for copyright transfer; and defence against copyright infringement claims. In the digital age, copyright enforcement increasingly involves takedown notices under the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021, and court orders directing internet service providers and platforms to remove infringing content.

A design registration under the Designs Act, 2000, protects the visual appearance of a product — its shape, configuration, pattern, ornament, or composition of lines and colours applied to any article. Design protection is particularly relevant for manufacturers of consumer goods, furniture, packaging, textiles, and industrial products. A design must be new or original, not previously published in India or any other country, and must be significantly distinguishable from known designs. Registration is valid for ten years (extendable by five years). Unlike trademarks (which protect brand identifiers) and patents (which protect functional inventions), designs protect purely aesthetic features. Advocate Panchanand Shaw advises clients on whether their intellectual property is best protected through design registration, trademark (including shape marks/trade dress), or copyright (for artistic works applied to articles) — and often recommends a multi-layered protection strategy combining all three.

The strongest IP registration is worthless without enforcement. Advocate Panchanand Shaw represents IP owners in enforcement actions before the Calcutta High Court and District Courts in Kolkata. Common enforcement actions include: (a) Trademark and copyright infringement suits — seeking permanent injunction restraining the infringer from using the mark/work, delivery-up/destruction of infringing goods, damages or account of profits, and costs. (b) Interim injunctions — often the decisive stage in IP litigation. If the IP owner secures an ex-parte ad-interim injunction early, the infringer's business is disrupted immediately, creating pressure to settle. (c) John Doe orders (Ashok Kumar orders) — injunctions against unknown defendants, used in anti-counterfeiting operations where multiple unknown infringers are operating (e.g., at local markets or online). (d) Criminal complaints — for trademark counterfeiting (Sections 103-104 of the Trade Marks Act, punishable with imprisonment up to three years and fine) and copyright piracy (Sections 63-64 of the Copyright Act). (e) Customs recordal — registering IP with Customs authorities to prevent import/export of counterfeit goods.
