An invention isn't an invention until it's written.
We put into words: patents, industrial designs, trademarks, utility models, appeal decisions, inventive step, claims, office actions, and PCT filings.
MEIKYO IP is a Tokyo patent firm specialized in the language of invention.
Most unprotected inventions are unwritten inventions.
Great technology goes unprotected. The cause is rarely the technology. It is the writing.
A patent lives or dies by the text an examiner reads. Its scope is fixed by a single sentence: the claim. Precision in writing becomes strength in rights.
We define our core work as putting inventions into language. Interviews, structuring, specification drafting: one discipline of language engineering.
That is why this site carries no photos and no decoration. Judge us by the precision of the text. It is a sample of our work.
