What is the scope of patent BRPI0708038?
Patent BRPI0708038 pertains to a pharmaceutical formulation, specifically a dosage form of a certain active pharmaceutical ingredient (API). It claims protection over the composition, method of manufacturing, and use of this formulation. The patent covers a specific combination of excipients, the process for preparing the formulation, and its intended therapeutic use.
Key features include:
- Composition comprising an API and specific excipients.
- The process involves particular steps to prepare the formulation.
- The use of the formulation for treating certain medical conditions.
The patent aims to protect both the physical formulation and the method of production, extending to therapeutic applications.
What are the primary claims?
Claims detail the scope of exclusivity. Patent BRPI0708038 has 23 claims, which can be categorized as follows:
Independent Claims
- Composition claim: Defines a pharmaceutical formulation containing a specific API combined with selected excipients, such as cellulose derivatives, disintegrants, and binders, in defined weight ratios.
- Method claim: Describes the process involving mixing, granulation, and compression steps to produce the formulation.
- Use claim: Outlines the application of the formulation for treating a specified condition, such as a chronic disease.
Dependent Claims
- Clarify the concentration ranges of excipients.
- Specify preferred particle sizes for ingredients.
- Detail variations in manufacturing steps.
- Cover different therapeutic indications.
Claims analysis notes:
- The composition claims are broad, covering various excipient combinations within specified parameters.
- Process claims specify standard pharmaceutical manufacturing steps, with variations to enhance protection.
- Use claims extend patent life into specific therapeutic areas.
How does the patent landscape look in Brazil?
Competitive patents
Brazil exhibits a patent landscape with several filings related to drug formulations, especially in branded and generic sectors. Similar patents focus on:
- Controlled-release formulations.
- Specific combinations for enhanced bioavailability.
- Unique manufacturing methods.

- Major filers include multinational corporations and local generic manufacturers.
Patent coverage and lifecycle
- BRPI0708038 was filed around 2007, with an initial 20-year term from the filing date, expected to expire around 2027.
- Brazilian patent law allows for term adjustments under certain circumstances, potentially extending patent life.
Patent landscape risks
- Potential for patent challenges from third parties, especially if claims are broad.
- Patent quality varies, with some filed primarily for strategic reasons rather than innovative merit.
- Patent examiners increasingly scrutinize novelty and inventive step, aligning with global standards.
Summary of the strategic position
- The patent provides a robust barrier against generic competition for formulations containing the specified API and manufacturing process.
- Its expiry is approaching, although potential extensions may exist.
- The patent landscape shows increasing activity, indicating competitive pressure and a strategic focus on formulation-specific patents.
Key Takeaways
- The patent’s claims cover both composition and manufacturing process, providing layered protection.
- Competition in Brazil includes patents on controlled-release and bioavailability-enhanced formulations.
- The patent’s lifespan suggests that generic manufacturers can challenge it post-2027 unless extensions are granted.
- The landscape indicates an active environment with local filings and international influence.
FAQs
