The question that decides most IP disputes is who owns it — and that is settled at setup, not in court
Brand and product disputes are usually lost long before anyone copies anything, at the moment ownership was arranged casually: a mark registered in a founder's personal name, a design commissioned without an assignment, or a formulation shared with a manufacturer under nothing in particular. We advise on getting ownership right at the outset — which entity holds what, and how it moves if the business is restructured or sold — and on protecting it afterwards through registration, contract, and enforcement where copying has already happened.
Service Scope
Who holds the mark matters more than when it was filed
A mark registered in a founder's own name, or in the name of an entity that later becomes a minority shareholder's, creates a problem that only surfaces when the business is raising money or being sold. Deciding deliberately which entity holds the brand — and putting assignments in place for anything created before that decision — is inexpensive at setup and disproportionately expensive to correct once there are other stakeholders.
Patent, petty patent, or keep it confidential
Registration publishes the thing being protected in exchange for a defined period of exclusivity. For some innovations that trade is clearly worth it; for others, particularly processes that are hard to reverse-engineer, protecting it as confidential information may be stronger and lasts as long as it stays confidential. That choice is strategic rather than administrative, and it should be made before disclosure to manufacturers or partners makes it moot.
Enforcement begins with proving ownership
When copying is discovered the instinct is to capture the infringement, which matters. What decides the outcome, though, is the evidence of your own ownership: registrations, records of creation, and assignments from whoever actually made the work. Where those are in order, a warning letter often ends the matter. Where they are not, the same letter invites a fight about title rather than about copying.
