Patent Law Editing and Proofreading Services

Patent prosecution is a long written conversation with an examiner, and it is preserved forever. Everything you say about your claims becomes file history, and file history is what a court reads years later when deciding what the patent covers. An imprecise sentence in a response to an office action can narrow a patent more effectively than any amendment.

We edit patent specifications, claim sets, responses to office actions and examination reports, PCT and national phase documents, invention disclosures, priority documents, and appeal briefs. Our editors check that claim terms are used identically in the specification, that every element introduced in a claim has proper antecedent basis, that reference numerals in the description match the drawings, and that dependent claims actually depend on claims that exist after amendments.

Consistency is the recurring failure. A component called a "coupling member" in claim 1, a "connector" in the description, and a "linkage" in the summary is one component with three names — and three opportunities for an examiner or an opponent.

Unpublished applications are treated as strictly confidential. We never alter claim scope; that decision is yours. We report where the language is inconsistent or ambiguous and leave the drafting call where it belongs.
