Key takeaways
- The baseline patent term under Law 20-00 is 20 years from filing, subject to maintenance and any qualifying statutory adjustment.
- Protection requires novelty, inventive step and industrial application.
- Public disclosure before filing generally creates prior art; narrow 12-month statutory exclusions should not replace a file-first strategy.
- The PCT national phase is the usual route for applicants with a foreign priority filing.
- Industrial designs protect appearance and are a separate, shorter-term right.
Patents are the least-used industrial property right in the Dominican market and the most misunderstood. Companies that would never launch a brand without a trademark filing routinely bring a technical product to market with no patent analysis at all — sometimes because they assume a foreign patent covers them here, and sometimes because they have already destroyed their own novelty by the time they ask.
What can be patented, and for how long
Under Law 20-00 on Industrial Property, ONAPI grants patents for inventions that are new, involve an inventive step and are capable of industrial application. The baseline term is 20 years from the filing date, subject to maintenance. There is no ordinary renewal, but amended Article 27 permits a one-time adjustment of up to three years for specified qualifying office or pharmaceutical-approval delay.
Certain categories fall outside patentability, in line with international practice: discoveries and scientific theories as such, mathematical methods, and subject matter excluded on public-order or health grounds. Where an invention sits close to one of those lines, the drafting of the claims does much of the work.
Territoriality, again
The point that costs companies the most is the same one that governs trademarks: protection is territorial. A granted US or European patent gives you nothing in the Dominican Republic. If the Dominican market matters — because you will manufacture here, because you will sell here, or because a licensee or competitor could copy here — the invention needs a Dominican filing.
For most foreign applicants that filing arrives through the PCT national phase. An international application filed under the Patent Cooperation Treaty establishes an international filing date, and Dominican national-phase entry produces a local application examined by ONAPI. Entry is generally due within 30 months of the earliest priority date. Any relief after a missed deadline is fact-specific and should not be assumed; seek advice immediately.
Disclosure is the trap
Public availability before the filing or priority date generally counts against novelty: a conference presentation, trade-fair demonstration, early product page or non-confidential pitch can become prior art. Law 20-00 excludes certain inventor-derived or unauthorised disclosures made within the preceding 12 months, but the conditions are narrow and require prompt factual analysis.
The practical discipline is simple and rarely followed. File first, or disclose only under a written confidentiality agreement. If a disclosure has already happened, the position needs assessment quickly rather than eventually, because whatever options exist are time-bound.
Industrial designs, and where they fit
Not every technical protection question is a patent question. Industrial designs protect the appearance of a product — its shape, configuration or ornamentation — rather than how it works. They are registered separately, run for a shorter term, and are frequently the right tool for consumer products whose commercial value lies in how they look. A product can be protected on multiple layers at once: the design as an industrial design, the technical function as a patent, the name as a trademark and the manuals and software under copyright.
What we do before filing
Three steps, in order. A prior-art search, to see whether the invention is actually new and to shape the claims around what is available. A decision on route and timing — direct filing or PCT national phase, and how that interacts with filings in other markets. And a disclosure audit, because what the client has already published often changes the advice more than the invention itself does. Our IP desk handles all three, alongside the trademark and copyright layers that usually accompany them.
Frequently asked questions
Does my US or European patent protect me in the Dominican Republic?
No. Patent rights are territorial, so protection in the Dominican Republic requires a Dominican filing, most commonly through entry into the PCT national phase before its deadline.
How long does a Dominican patent last?
The baseline term is 20 years from filing, subject to maintenance. There is no ordinary renewal, although amended Article 27 permits a one-time adjustment of up to three years for specified qualifying delay.
I already showed the product at a trade fair. Can I still file?
Public disclosure generally creates prior art. Law 20-00 excludes certain inventor-derived or unauthorised disclosures made within the 12 months before filing, but the exception is narrow and should be assessed immediately.
What is the difference between a patent and an industrial design?
A patent protects how an invention works; an industrial design protects how a product looks. They are separate registrations with different terms, and many products are worth protecting on both layers.
