Lesperance & Martineau - Patent Agents

Patent & Trademark
    Agents since 1929

Professional staff

Our staff includes patent agents registered before the Canadian and American patent offices, and a trade-mark agent registered before the Canadian Trade-Mark Office. We can thus act on behalf of our clients without any intervening agents, before the patent offices of these two countries.

We work most frequently with inventions pertaining to the following technical fields: mechanics, electromechanics, electronics, computer sciences, chemistry, biology and optics.

Here is a short resumé of our professional staff:

Mr. François Martineau (since 1982)

Mr. Louis Martineau (since 1992)
