Patent Preparation and Drafting
The patent specification is the document every examiner, licensee and court will read. A well-drafted application moves through examination with fewer objections and is hard to design around. A poorly drafted one invites delays, costly amendments, narrow claims and weak enforceability. However strong the technology, a patent loses value if its disclosure cannot be reproduced, if it leaves out important embodiments, or if its claims are narrower than the specification supports. We draft applications that capture the full scope of the invention and hold up in prosecution, licensing and litigation.
What We Offer
Provisional specifications to secure an early priority date while the invention is still being developed. The complete specification must follow within 12 months, or the application is treated as abandoned.
Complete specifications with title, field, background, summary, detailed description, claims, abstract and drawings.
Drafting to the standards of each office, including the Indian Patent Office, USPTO, EPO, JPO and PCT.
Pre-drafting state-of-the-art and novelty searches, to shape the claims around existing prior art.
Review and redrafting of applications prepared by in-house teams or other counsel.
Our Approach
Search first. Where appropriate, we run state-of-the-art and novelty searches before drafting, so the claims are positioned against what already exists.
Disclosure meeting. We meet inventors and legal teams in person, by video or by phone to understand the invention, its variations and its commercial use.
Claims built in layers. Independent claims are drafted as broadly as the prior art allows. Dependent claims provide fallback positions. All claims are fully supported by the description.
Objections anticipated. We address foreseeable objections in the specification itself, including the exclusions in Section 3 of the Patents Act for software, business methods and new forms of known substances.
Multi-tier review. Every draft goes through technical review, legal review and proofreading before it is shared for filing.
