I perform premium quality translations of patents and patent applications, and related documents involving: prosecution, opposition and litigation (prior art, filings, pleadings, notices, office actions, opinions of the search authority, briefs, court and administrative decisions, and expert witness reports).

I am available as an expert witness on the subject of accuracy of patents translated from French into English.

I provide relevant statements and declarations, including statements of accuracy required by Title 37 CFR 1.52(d)(1).

I am also interested in the mathematical and scientific writings of Henri Poincaré. I translated Sur le problème des trois corps et les équations de dynamique by Henri Poincaré and it was published in 2017 by Springer, catalog entry. My second book, Henri Poincaré: Electrons to Special Relativity, is now in production with Springer Nature for publication later in 2020, catalog entry. Please see my pages on Poincaré.
