Once a Chilean design application clears substantive examination, it's published for a statutory opposition period before registration. Our team at Brealant represents clients opposing a published design that conflicts with their rights, and those defending their own design against an opposition.

Legal Definition of Design Opposition
Opposition is the formal process, under Ley N° 19.039, that lets a third party challenge a design application after it's published in the Diario Oficial but before registration.
Purpose and Function of Opposition
It exists to let holders of earlier rights, or others with a legitimate interest, prevent a design that isn't genuinely new or original from reaching the register.
Protecting Your Position
Whether opposing or defending, prior art evidence and a carefully built case are essential to a successful outcome before INAPI.

In Chile, design opposition follows publication of an application that has cleared substantive examination: a statutory window opens for third parties to oppose, the applicant is given a chance to respond, and INAPI decides before registration is granted. Knowing exactly where a case sits in that sequence is the clearest way to plan next steps.
Opposition is a meaningful step with real cost implications, so it's worth a clear-eyed assessment of the published design, the strength of your prior art, and the commercial risk of letting it proceed unopposed. Brealant assesses the merits with you before recommending action.
Opposition is a useful tool, but it has real limits
Missed Deadlines
An opposition must be filed within the statutory window after publication — miss it, and the right is generally lost.
No Retrospective Effect
Opposition can't undo a design that has already registered; the grounds would need to be raised differently after grant.
Cost and Time
A contested opposition adds real time and professional cost to the registration timeline.
Burden of Proof
The opponent must substantiate its grounds with credible prior art or other evidence.
Partial Outcomes
Opposition may only succeed for some elements or representations of the design, not necessarily all of them.
Brealant gives you a realistic view of the likely outcome, timeline, and cost before you proceed.
A well-run opposition protects a range of commercial and legal interests
Your Existing Product Line
Preventing a design that copies or closely resembles yours from reaching the register.
Market Fairness
Ensuring only designs that are genuinely new and original proceed to registration.
Your Freedom to Operate
Stopping a competitor from gaining a registration that could later be used to restrict your own product.
Register Integrity
Keeping the Diseños Register reflective of designs that genuinely meet the legal requirements.
Brealant helps you weigh these interests against the cost and time of a contested opposition before you commit.

INAPI Decision
INAPI decides whether to proceed to registration, in whole or in part.
A contested design opposition in Chile commonly adds several months to the overall registration timeline.
Costs scale with how far the matter proceeds

INAPI charges a modest official fee to file a design opposition.
Professional fees depend on the complexity of the prior art and arguments involved.
Brealant gives you a realistic view of the likely outcome, timeline, and cost before you proceed.
Brealant manages your opposition matter end to end, keeping you informed at each stage and revisiting strategy as the case develops, so you can make informed decisions about whether to continue or resolve the matter another way.

Any person or business with a legitimate interest can file an opposition, most often the holder of an earlier or conflicting design.
After the application has cleared formal and substantive examination and been published in the Diario Oficial, within the statutory opposition window that follows.
Yes — Chile runs a pre-grant opposition process after substantive examination and publication, unlike jurisdictions such as Australia, where a design's validity is only tested after registration.
If the opposition succeeds, the application is refused, in whole or for the contested elements, and does not proceed to registration.
Yes, some oppositions resolve through negotiation or amendment before INAPI issues its decision.
There's an official INAPI filing fee plus Brealant's professional fee for preparing and arguing the opposition, which we quote before starting.
Proof of your earlier right, such as a registration certificate or evidence of prior disclosure, plus a visual comparison showing why the applied-for design lacks novelty or original character.
The application proceeds to registration, but you can generally appeal INAPI's decision to the Tribunal de Propiedad Industrial (TDPI).
Third parties have a statutory period following publication in the Diario Oficial to file an opposition — Brealant monitors this window and confirms the exact deadline.
Opposition is the main pre-grant challenge; once registered, a design can still potentially be challenged through separate nullity proceedings on similar novelty grounds.
