Patent Drafting & Filing —
Claims That Hold Up
in Court
A patent is only as strong as its claims. Weak drafting means weak protection — and a granted patent with narrow claims can be designed around by competitors. TaxClue's registered patent agents draft technically precise, strategically broad specifications across all technology areas and file on the Indian Patent Office portal.
What a Complete Patent Specification Contains
A complete patent specification is a legal document of exceptional technical precision. Every section plays a strategic role — from the description that teaches the invention, to the claims that define the monopoly. TaxClue drafts all sections to work together as a coherent legal instrument.
Under the Patents Act, 1970 and the Patents Rules, 2003, a complete specification must include each of these components — drafted to maximise both the breadth and enforceability of protection: Title of Invention, Field of Invention, Background / Prior Art, Summary of Invention, Detailed Description, Claims (the monopoly definition), Abstract, Drawings/Figures, and Sequence Listing (if applicable).
Claims — Where TaxClue's Drafting Makes the Difference
Claims define exactly what you own. TaxClue drafts independent claims as broad as the prior art allows, with dependent claims that create layers of fallback protection — ensuring that even if a broad claim is challenged, narrower claims survive. We typically draft 10–25 dependent claims creating a multi-layer protection structure.
