We help you manage and protect your innovations and brands.

We identify what protection may be available and what risks may exist. We lay out your options for a path forward. We help you brainstorm new opportunities. We manage the preparation, filing and prosecution of patent, design or trademark applications in Canada and around the world.  We help you negotiate commercial deals in respect to IP from initial term sheet to final agreement.
