Core Patent Services 

Patent Search & Prior Art  

Comprehensive searches across Indian and global patent databases. Novelty opinions, landscape analysis, and freedom-to-operate reports prepared by experienced patent professionals. Patent searches help you manage your idea/invention by providing a complete picture of existing inventions and technologies. It helps to identify relevant prior art and potential conflicts or overlaps with existing inventions/technologies to assess the patentability of inventions and reduce the risk of infringement. Patent searches are categorized into different types, each with a specific purpose, to address multiple objectives such as Novelty or Patentability Search, Invalidity Search, FTO SearchInvalidity Search and Landscape Analysis. 

Patent Drafting & Filing

A patent application is a techno-legal document through which an inventor secures exclusive rights over an invention in exchange for a complete and enabling disclosure. Such protection restricts others from making, using, selling, or importing the patented invention without authorization.  One of the core requirements for patentability is novelty; the invention must not have been disclosed to the public in any manner prior to the filing date. Accordingly, before initiating the drafting process, comprehensive searches such as state-of-the-art and novelty searches are undertaken to evaluate the invention’s novelty and inventive step. Upon establishing these aspects, the process proceeds to careful patent drafting, where all technical features are precisely and comprehensively captured to ensure strong protection and enforceability.  Meticulously drafted patent applications that accurately describe your invention and define broad, enforceable claims. We file provisional, complete, and PCT applications with the Indian Patent Office and foreign offices.
