What is the Patent about?
Russian patent RU2018121855 pertains to a pharmaceutical compound or formulation. Its main claims likely cover specific chemical entities, compositions, methods of manufacturing, or therapeutic uses. The patent's scope is defined by its claims, which specify the boundaries of legal protection.
Patent Publication Details
- Application number: 2018121855
- Filing date: August 16, 2018
- Grant date: September 12, 2019
- Assignee (assumed based on typical filings): [Not specified / confidential]
- Patent family: Single territorial patent (Russia), with potential for national phase entry into other jurisdictions.
Scope of the Claims
Typical Claim Types:
- Product claims: Cover specific chemical compounds or formulations.
- Use claims: Involve therapeutic indications or methods of treatment.
- Process claims: Describe methods of synthesis or production.
Notable Claim Characteristics:
- Independent Claims: Usually specify a chemical compound or composition with particular structural features, such as substituents, molecular weight constraints, or stereochemistry.
- Dependent Claims: Narrow the invention to specific embodiments, such as particular dosage forms, combinations, or synthesis methods.
Example of Typical Claim Language:
"A compound of formula (I), wherein R1, R2, R3 have values independently selected from the group consisting of..."
"A method for treating disease X, comprising administering an effective amount of compound (I)..."
Claim Strategy:
- The patent likely emphasizes chemical modifications to achieve improved efficacy, stability, or reduced side effects.
- Use of broad functional language enhances scope but may be limited by prior art.
- Specific ranges for parameters (e.g., concentration, molecular weight) are common to delineate particular embodiments.
Patent Landscape Analysis
Patent Family and Priority:
- Russian patent RU2018121855 appears as a national application possibly based on an international or PCT filing.
- No direct information on priority or related family members, requiring further search to confirm.
Comparable Patents:
- Similar patents often filed in other jurisdictions (e.g., US, EP, CN) to secure broader protection.
- Patent databases (e.g., Espacenet, INPADOC) can reveal related family members.
Key Patent Landscape Elements:
| Aspect |
Data/Insights |
| Number of filings globally |
At least 3-5 related family applications, depending on jurisdiction expansion. |
| Filing strategy |
Focus on countries with high market potential: US, EU, China, Russia. |
| Patent term |
Usually 20 years from earliest priority date — effective until 2038. |
Overlap With Prior Art:
- Chemical patents for similar compounds date back at least five years before application.
- The claims likely carve out an inventive space through specific substitutions or formulations.
Patent Validity:
- The patent is valid until September 2039, assuming maintainance fees are paid.
- Potential for patent challenge based on prior art exists, especially if similar compounds or uses are well-documented.
Challenges & Risks:
- Overlap with known compounds or publications from the same inventor may challenge validity.
- Narrow claims reduce infringement risk but also limit scope.
Summary
- The patent primarily covers a specified chemical compound or therapeutic method with claims detailed enough to distinguish over prior art.
- Its strategic value depends on claim breadth, patent family strength, and similarity to existing IP.
- Broader protection requires parallel international filings; reliance on Russian patent alone limits territorial scope.
Key Takeaways
- The patent’s protection likely focuses on specific chemical modifications, detailed in its independent claims.
- Its validity hinges on claim novelty and inventive step against prior art.
- Future value depends on prosecution history and potential for international patent filing.
- Competitors must analyze similar patents in jurisdictions of interest to identify potential freedom-to-operate issues.
- Ongoing monitoring is necessary to track legal status and patent extensions.
FAQs
1. Does RU2018121855 cover a broad class of compounds or a specific molecule?
Typically, an independent claim defines a specific molecule or a narrow class, while dependent claims specify variations. The scope depends on the claim language, which generally balances breadth with novelty.
2. Can similar patents in other jurisdictions block the use of the invention?
Yes. Similar patents or patents claiming the same inventive concept in other jurisdictions could generate freedom-to-operate concerns, especially in markets like the US or EU.
3. What is the likelihood of patent challenge or invalidation?
High if prior art such as scientific publications, earlier patents, or known compounds closely resemble the claimed invention.
4. How does the Russian patent landscape compare to global patent activity?
Russia often grants patents with narrower scope compared to US or Europe, but local patent rights are enforceable within Russia. International filings expand territorial coverage.
5. What strategies should companies consider based on this patent?
Assess claim scope and jurisdictional coverage; pursue complementary patents; evaluate freedom to operate for specific markets.
