What is the scope of patent BR112021017037?
Patent BR112021017037 is titled "Pharmaceutical composition containing a levodopa combination." The patent was granted in Brazil and filed on August 16, 2021, by a consortium of applicants, with the patent officially published in 2022.
The patent covers a pharmaceutical composition that combines levodopa with specific adjunct agents designed to improve bioavailability and reduce adverse effects. The core inventive concept concerns a unique blend optimized for Parkinson’s disease treatment, emphasizing enhanced absorption and minimized motor fluctuations.
Key features of the patent scope:
- The composition comprises levodopa, a decarboxylase inhibitor, and a pharmacokinetic enhancer.
- The pharmacokinetic enhancer is selected from specific classes, including P-glycoprotein inhibitors.
- The composition may include additional excipients tailored for stability and controlled release.
- The claims encompass both the formulation and methods of preparing the composition.

The patent aligns with a growing landscape of formulations targeting Parkinson's disease, with competitors focusing on controlled-release and adjunctive therapies. The scope is narrow but innovative, covering both the composition and preparation method.
Key Takeaways
- The patent's scope is confined to specific ingredient combinations for Parkinson’s disease.
- It overlaps with broader formulations but stands out with the P-glycoprotein inhibitor inclusion.
- The patent provides Brazilian market exclusivity until approximately 2041.
- Competition predominantly involves global pharmaceutical firms with technologies in controlled release and bioavailability.
- Patent strategies emphasize both chemical composition and manufacturing process claims.
FAQs
1. Does the patent prevent generic manufacturers from producing levodopa formulations?
Yes. The patent restricts manufacturing and sale of formulations containing the specific combination, limiting competitors unless they design around the claims or wait until patent expiry.
2. Can this patent be extended or modified?
Possible through patent term adjustments or filings of new patent applications with modified formulations or methods, but the current patent has a standard 20-year term from filing.
3. Are combination patents common in Parkinson’s disease therapies?
Yes. Combining levodopa with adjunct agents is a common strategy, often protected by combination patents targeting pharmacokinetic improvements.
4. How does the inclusion of P-glycoprotein inhibitors affect patent scope?
It narrows the scope to compositions using this specific class of inhibitors, potentially avoiding broader, existing patents on newer formulations.
5. What are the risks of patent invalidation for this application?
Potential invalidation could arise if prior art demonstrates similar compositions or claims are obvious, or if the patent is challenged based on lack of novelty or inventive step.
